- MEANWHILE, I continued my search, for the investigation of infant
- mortality had revealed still another possible dimension of the effects
- from fallout. As Dr. I. M. Moriyama put it in the introduction to his
- 1964 report entitled "The Change in Mortality Trend in the United
- States":
-
- The same kind of change in trend observed for infants appears to
- be taking place in the death rates for other ages.
-
- Regarding the overall trend, he added:
-
- The failure to experience a decline in mortality during this
- period is unexpected in view of the intensified attack on
- medical problems in the postwar years . . . there has been a
- growth in the volume and scope of health services in prevention,
- diagnosis, medical and surgical therapy, and rehabilitation, and
- also an improvement in their quality. The rapid growth of
- health insurance plans has made high quality medical care
- readily accessible to ever-increasing numbers of people. The
- rising level of living has resulted in improvement of work and
- home environment, quality and variety of food, educational
- attainment, and facilities of recreation. Developments in
- medicine arising from the exigencies of a global war have become
- readily available for application to civilian health problems.
- At no time in the history of the country have conditions
- appeared so favorable for health progress.
- In this setting, it would seem reasonable to expect further
- reductions in mortality. On the other hand, the possible
- adverse effects on mortality of radioactive fallout, air
- pollution, and other manmade hazards cannot be completely
- ignored.
-
- In the School of Public Health library, page after page of data
- showed the same dramatic upward changes for chronic diseases as had
- occurred for childhood leukemia and fetal and infant mortality.
- Deaths from all types of noninfectious respiratory diseases such as
- lung cancer, emphysema, and bronchitis had increased especially
- dramatically among all age groups, as had deaths from certain other
- types of cancer. The overall life expectancy, particularly for adult
- males, had begun to level off and then actually declined again after
- decades of steady rise in this country and in northern Europe.
- Most significant of all were the death rates due to all types of
- childhood cancers in the U.S. For young people of both sexes, white
- and nonwhite alike, there were sudden, steplike jumps in the cancer
- rate between 1948 and 1951. For the white children, the rate doubled
- during these three years. The rate for the nonwhite children, which
- had held basically steady between 1930 and 1948, tripled during the
- same three-year period. This was to be expected if fallout was the
- cause, since by far the largest portion of the nation's nonwhite
- population lived in the regions where the fallout from the early tests
- came down.
- When had this overall trend begun? Dr. Moriyama's report indicated
- that deaths from respiratory diseases and childhood cancers either
- declined steadily or held level throughout the 1930s and most of the
- 1940s, the period of rising air pollution and the tripling of
- cigarette consumption. Between about 1948 and 1950, three to five
- years after the detonation of the first bombs in New Mexico and Japan
- and the onset of atomic testing in the Pacific, the death rates from
- these diseases suddenly began to shoot up. For example, the annual
- death rate among white males seventy-five to eighty-four years old
- from respiratory diseases (not including influenza and pneumonia) was
- close to 110 per 100,000 per year in 1934. By 1948 it had declined to
- an all-time low of about 70. But after this it shot up to 190 by
- 1960.
- The sharp upward changes in the rates for these types of chronic
- diseases were reflected in an overall leveling in the decline of death
- rates for the United States as a whole. But this effect was
- particularly serious in certain states, where the death rates actually
- rose again after decades of steady decline. As Moriyama pointed out:
- "In twelve states and the District of Columbia there appears to be a
- marked rise in the crude death rate during the past five to ten years
- as represented by the trend for North Carolina." The list of the
- states showed that they were all either southern states to the east of
- New Mexico and Nevada, or states directly to the northeast of the
- Nevada test site. The states were Alabama, Arkansas, the District of
- Columbia, Louisiana, Missouri, North Carolina, South Carolina,
- Tennessee, and West Virginia in the South, and Nevada, Colorado, South
- Dakota, and Wyoming in the West. None of these states was heavily
- industrialized or noted for its air pollution. In fact, the opposite
- was true.
- The number of excess deaths in the U.S. resulting from these upward
- changes in the death rates was calculated by Dr. Moriyama as being
- 300,000 during 1956-60. This was the period of heavy Nevada testing.
- The fallout and the excess deaths continued as testing resumed in
- 1961. According to Moriyama, "The estimated excess deaths is about
- 85,000 deaths for 1961, and 131,000 deaths for 1962." The "excess
- deaths" had jumped from an average of 60,000 per year during the
- earlier period of testing to 85,000 in 1961, the year that the
- Russians detonated the largest megaton weapons ever exploded. In the
- following year, when nearly 70 megatons of fission energy were
- detonated by the U.S. and the Soviet Union--the highest megatonnage
- ever exploded in a single year--the excess deaths in the United States
- alone reached 131,000.
- The same trends were also evident in other parts of the world. A
- detailed report on changes in mortality trends for England and Wales
- by Hubert Campbell at the Welsh National School of Medicine showed
- that in those countries the mortality rates for the very young and the
- very old followed exactly the same pattern as in the U.S. Beginning
- about 1953-55 the total death rates for 1- to 4-year-olds suddenly
- refused to decline further. For the 5- to 9-year age groups, which
- the studies of Stewart and MacMahon had shown to reflect most strongly
- the cancer-causing effect of irradiation during early development, the
- mortality rate actually started to climb again. Beginning the year
- after the first Nevada tests, there was also the same sudden halt in
- the rapid decline of maternal mortality associated with complications
- of pregnancy and childbirth as in the U.S. These rates actually
- turned sharply upward in 1960-61 for the youngest group of women (15
- to 24 years of age) for the first time in modern history. And there
- was the same sharp rise in cancer deaths of all types for the age
- group 5 to 14 years, following some three to five years after the New
- Mexico test and the detonations in Japan in 1945. Both male and
- female death rates jumped in a steplike fashion: from about 30 per
- million per year to about 60 for boys, and from 25 to about 50 for
- girls, all between 1948 and 1951, exactly as in the United States.
- That these rises could not be due to changes in statistical or
- classificational methods was emphasized by Campbell: "There has been
- no important change in the classification of these diseases during
- this period. . . ."
- For all age groups in England and Wales, Campbell's report showed
- tremendous rises in leukemia for both men and women, beginning
- suddenly between 1947 and 1951, with the sharpest changes for the very
- young and the very old. Thus, whereas the leukemia death rate had
- remained fairly steady for men 75 to 84 years old during the fifteen
- years between 1931 and 1946, ranging from 50 to 80 deaths per million
- individuals each year, by 1954 the rate had increased to about 200.
- It reached 350 by 1959, an increase of about 500 percent. During the
- same period, the leukemia rate remained unchanged for the middle-aged
- group 45 to 54 years old, but it increased some 50 percent for boys 5
- to 14 years of age. This was the rise that had prompted Dr. Stewart's
- study.
- The data for Japan, prepared by a group of public health physicians
- and statisticians from the Japanese Institute of Public Health, was
- particularly significant, since Japan was not only exposed to the
- fallout from the Hiroshima and Nagasaki bombs, but also received the
- radioactive debris from the U.S. Pacific and Soviet Siberian tests.
- The report showed that three to five years after the fallout from
- Hiroshima and Nagasaki descended in 1945 the cancer rate for the 10-
- to 14-year-old children all over Japan tripled from 10 to 30 cases per
- million population, gradually climbing further to 40 cases by 1955 and
- to 50 by 1963, a fivefold increase during the period of heavy testing.
- For the youngest children zero to 4 years old, the increase was less,
- once again confirming the hypothesis that radiation was the causative
- factor as in the case of Troy. Again, the rates for the middle-aged
- group remained level, while the rate for those over 80 went up as
- elsewhere, in the case of Japan from about 3000 to 8000 per year per
- million individuals.
- Here then was the confirmation of why the studies of the Hiroshima
- and Nagasaki survivors had not revealed any effects on their children.
- Everywhere in Japan, mortality rates had gone up due to the fallout,
- so that there was little or no difference between those survivors
- exposed to the direct flash and those who received the fallout in
- their diet over the years that followed.
- And after the large hydrogen bomb tests, deaths due to
- noninfectious lung diseases such as emphysema and bronchitis suddenly
- stopped declining in Japan after 1955. This was the year after the
- Pacific and Siberian tests filled the air all over the world with
- radioactivity. In the next two years, deaths due to bronchitis, which
- had been dropping rapidly from 150 per million population in 1950 to a
- low of 40 by 1955, actually began to rise again. Thus, in the period
- from 1945 to 1955, when industrial growth and the accompanying smog
- and chemical pollution had been very great, these respiratory diseases
- had been declining. As in the United States, they rose only after the
- enormous increase of atmospheric radioactivity.
- If the major factor was fallout and not the pollution produced by
- industry and the automobile, then Chile provided an excellent chance
- to test this hypothesis in a country of low industrialization, as it
- was the only South American country for which detailed mortality-trend
- data was available. Since Chile was located on the west coast of
- South America, facing the prevailing winds from the South Pacific that
- release their moisture on the steeply rising slopes of the Andes,
- there should be upward changes in mortality following the first two
- series of Pacific A-bomb tests in 1946 and 1948. And these increases
- should be even more noticeable for the heavy series of tests beginning
- in 1952, involving the "dirty," uranium-clad hydrogen bombs that had
- produced such massive amounts of fission products.
- The Chile mortality graphs instantly confirmed this prediction,
- especially the plot of mortality for the infants dying between the
- ages of one month and one year, which showed an initial rise between
- 1947 and 1949 after the first Bikini and Eniwetok tests. Far more
- serious was the sudden and complete reversal of the overall infant
- mortality trend, from a steady decline to a continuous rise beginning
- in 1954 and persisting until 1960, the last year for which data were
- available.
- And the same change had taken place in the total mortality rate for
- all ages combined. There had been a steady decline after 1933, except
- for small rises during the second half of the 1940s, but then between
- 1953 and 1955 there was a sudden and complete end to the decline for
- both men and women, continuing for as long as the data had been
- plotted.
- In the words of the report's authors, a group of Chilean public
- health specialists:
-
- The significance of this trend is evident if the mortality for
- 1960 is estimated on the basis of regression for 1933-53. The
- expected rate was 8.6 and the observed rate was 12.3, which
- means that 28,024 of the total 93,265 deaths registered in 1960
- would not have taken place if the previously described trend had
- continued.
-
- This did not mean that cigarettes or air pollution were not
- significant factors in chronic lung disease, or that heavy metals,
- pesticides, food additives, and other pollutants were not adversely
- affecting worldwide health. The phenomenon of synergism, in which
- combinations of two or more biological agents have a much greater
- effect than one alone, is well known to modern science. For instance,
- it has long been known that uranium miners have ten times the normal
- rate of lung cancers because of their breathing of radioactive gas in
- the mines. But those who smoked died of lung cancer at one hundred
- times the normal rate.
- However, statistics from all over the world kept indicating that
- radiation was the dominant factor in these worldwide changes of
- mortality trends. It made no difference what the social or economic
- system was, nor how much medical care was available, as in the very
- different cases of the Netherlands versus Chile. It made no
- difference whether infant mortality was high or low to begin with, as
- in Mississippi versus Sweden. It did not matter whether there was any
- air pollution, or what the genetic, cultural, or dietary differences
- were. There was only one way to explain these worldwide, synchronous,
- and totally unexpected changes that did not stop at any national
- boundaries nor at the edges of the seas. Only the introduction of
- some new and enormously powerful biological agent on a worldwide scale
- could produce such sudden rises in death rates that could almost be
- termed epidemics. And this new agent clearly seemed to be the fallout
- that had been released into the atmosphere in quantities equivalent to
- tens of millions of pounds of radium, the most powerful biological
- poisons yet created by man, circling the world in a matter of a few
- weeks and attacking mainly the weakest in every living species--the
- developing young and the very old.

- The Clouds of Trinity
-
-
-
-
- THE GEOGRAPHIC PATTERNS of the changes in worldwide leukemia and
- infant mortality trends between 1945 and 1955 clearly matched the
- patterns of fallout. But so unbelievable and far-reaching a
- conclusion required much more evidence before the possibility of any
- other explanation could be ruled out. Laboratory-animal experiments
- had shown that various pesticides, drugs, food additives, and heavy
- metals could apparently cause cancer and congenital defects, while air
- pollution and mothers' cigarette smoking were believed to be linked to
- fetal and infant mortality.
- There was one test, however, that would effectively rule out these
- agents as the principal factors in the increase. It would involve the
- first nuclear explosion ever set off by man. Code-named Trinity, this
- explosion took place at dawn on July 16, 1945, in Alamogordo, New
- Mexico. Before this, there was no nuclear fallout in the environment,
- so this explosion would have to have produced a clear effect on
- mortality rates wherever the fallout descended.
- But where had the fallout come down? There was at that time no
- elaborate countrywide network of fallout-measuring stations. However,
- many eyewitness accounts of this historic explosion had subsequently
- been published, and, among these, a book called {Day of Trinity} by
- Lansing Lamont reported the event in greatest detail. Lamont, a
- {Time} magazine reporter, had gone to considerable lengths to trace
- the direction of the drifting radioactive debris, studying weather
- maps and conducting extensive interviews with many of the scientists
- involved.
- According to Lamont, shortly before the final countdown at 5:10
- A.M. on the morning of July 16, Dr. Kenneth Bainbridge announced to
- the scientists at the various observation posts that the winds close
- to the ground were blowing north, toward where Dr. Robert Wilson was
- manning an observation post 10,000 yards from ground zero. An instant
- after the flash of the detonation at exactly 5:29 A.M., the churning
- fireball detached itself from the ground and shot upward, followed by
- a column of radioactive dust, penetrating the overcast at 15,000 feet.
- The column of dust continued upward to an altitude of 40,000 feet,
- where it spread out in the mushroom shape that was later to become so
- familiar.
- The lower part of the mushroom's stem was blown north toward
- Wilson's position, which had to be quickly evacuated. Simultaneously,
- Dr. Luis Alvarez and Navy captain William Parsons, flying high above
- the cloud cover just to the west of the test site in an observation
- plane watched the head of the mushroom penetrate the overcast and
- break up into three distinct sections. These sections drifted off in
- different directions, generally to the northeast and east. As
- recounted by Lamont, the largest of the three sections, a dense white
- mushroom trailed by a dusty-brown streamer, drifted off in a direction
- just slightly north of east. Meanwhile, the low-altitude fallout from
- the stem of the mushroom cloud continued north and northeast until it
- covered an area about 30 miles wide and 100 miles long, gradually
- settling to the ground in a white mist of intense radioactivity.
- By three o-clock in the afternoon, the readings on the radiation
- counters monitored by Alvin Graves and his wife, Elizabeth, observers
- assigned to the little town of Carrizozo some 40 miles just slightly
- north of east from the test site, started to climb rapidly. By 4:20
- P.M., eleven hours after the explosion, the counters shot off scale
- and Alvin Graves called Dr. Stafford Warren, the chief medical officer
- in charge of radiation monitoring. As Lamont put it, the fate of the
- little town hung in the balance while the scientists and Army officers
- decided whether or not to evacuate it. Ultimately, they held off, and
- within an hour the fallout readings had dropped. Lamont reported that
- these were difficult hours for Dr. Warren and the officer in charge of
- the entire project, General Leslie R. Groves. "The medical dangers
- were most immediate of all," Lamont wrote, "but, in addition, both men
- knew that the Army was not too eager to pursue too diligently the
- possibilities of widespread fallout."
- From the fact that it had taken the fallout particles some nine to
- eleven hours to reach Carrizozo, it was possible to determine which
- portion of the cloud had gone eastward. According to the AEC
- publication {The Effects of Nuclear Weapons}, typical fallout
- particles descend at a speed of about 5000 feet per hour, while
- smaller particles fall more slowly. Allowing about half an hour for
- the cloud to travel the 40 miles to Carrizozo at the usual speed of
- the jet-stream air currents, then, it meant that the particles that
- caused the Graveses' radiation counters to start climbing must have
- taken about eight to nine hours to descend at a rate of 5000 feet per
- hour. Therefore, the cloud that passed over Carrizozo must have been
- at an altitude of between 40,000 and 45,000 feet.
- Thus, it had to have been the uppermost section of the mushroom
- cloud that drifted just slightly north of east. And since the winds
- became more northerly with decreasing altitude, the lower, smaller
- sections would have gone increasingly northward. This estimate was
- confirmed by the fact that the more northerly towns were the first to
- receive the fallout, and those to the east were the last. The low-
- altitude fallout, therefore, had come down mostly in New Mexico to the
- northeast, while the highest portions would have been carried more
- nearly eastward across Texas, Oklahoma, Arkansas, and the whole
- southeastern U.S., where they would be brought down mainly by the
- rain.
- On the basis of these estimations, then, any upward changes in
- infant mortality should be found to some degree in the sparsely
- populated areas of New Mexico itself, and to a greater extent in the
- more heavily populated states to the east, northeast, and north.
- Among the more distant states generally to the east, those with the
- heaviest rainfall should show the largest upward changes, since the
- high-altitude cloud carried the smallest particles, which would
- largely remain aloft unless brought down by rain. Furthermore, the
- states near the Atlantic seaboard to the northeast, such as North
- Carolina and Virginia, should be affected less than nearby Arkansas,
- Louisiana, and Mississippi, for the cloud would have gradually fanned
- out and the short-lived radioactivity would have steadily diminished
- in intensity with the passage of time.
- The five-year period 1940-45 was the longest period immediately
- preceding the test during which a steady decline in infant mortality
- had existed in every state in the U.S. Thus, the amount of upward
- deviation from this rate of decline would provide a measure of any
- changes occurring after the explosion.
- When the infant mortality figures were plotted on a map of the
- U.S., the pattern began to emerge. The states directly to the west
- and far to the northeast of New Mexico kept declining at the 1940-45
- rate. In fact, in some cases the decline was actually somewhat
- faster, due to the introduction of sulfa drugs and antibiotics, since
- the greatest cause of infant deaths was the infectious diseases that
- these new drugs succeeded in cutting back. But each year after 1945
- and beginning strongly in 1947, there was a growing excess infant
- mortality in the states of the Gulf and Atlantic coasts to the east
- and northeast of the test site, amounting to as much as 30 to 40
- percent. This pattern extended over the entire southeastern part of
- the country, from Texas, Arkansas, Louisiana, and Mississippi all the
- way across Alabama and Georgia to South Carolina, North Carolina, and
- Virginia, and existed both for the poorer nonwhite as well as for the
- socio-economically better-off white infants.
- Two of my colleagues, Donald Sashin and Ronald Rocchio, became
- quite concerned about these findings and offered to work out a
- computer program to calculate and plot the infant mortality rates for
- every state, thus removing any possible subjective bias. The pattern
- that emerged from the computer was essentially the same except for one
- striking difference. For some reason the computer maps showed
- excesses in infant mortality for the north-central region of the U.S.,
- in Montana, Idaho, Wyoming, and especially North Dakota. In 1946,
- even before the increased infant mortality manifested itself to the
- east of New Mexico, North Dakota was showing a 19 percent increase,
- reaching 32 percent in 1949. But the low-altitude fallout that went
- northward from the Trinity test could not possibly have been
- significant in these distant states so directly to the north.
- The mystery was solved when a colleague happened to show me a copy
- of an AEC publication entitled {Meteorology and Atomic Energy}. In
- the opening chapter, dealing with the history of the atomic energy
- industry, the report explained that in 1944 the first of a series of
- giant nuclear reactors had gone into operation in Hanford, Washington,
- to produce the plutonium for the Trinity bomb. The reactor was
- located in the dry eastern edge of the state of Washington, directly
- upwind from Montana, Idaho, and North Dakota. Because the operating
- engineers did not have sufficient experience with these enormous new
- reactors being built under wartime pressures, large releases of
- radioactive gases occurred. As the AEC report described it:
-
- As soon as a charge of fuel came out of the plutonium production
- reactors, a large source of gaseous effluent was encountered.
- For the plutonium produced to be removed from the uranium and
- other fission products, it was necessary to dissolve the fuel by
- various chemical reactions. During the early stages of this
- process, all the noble-gas fission products, notably radioactive
- isotopes of xenon and krypton, were released. It was not
- feasible to remove them by a filter system; they were released
- to the atmosphere in rather large quantities.
-
- Still more disturbing was the statement that "large quantities of
- radioactive iodine were involved." Additionally, when the reactor's
- fuel elements would occasionally catch fire, krypton and biologically
- more hazardous fission products such as strontium and cesium were
- driven off.
- Not only could this account for the sharp rise in infant mortality
- in the northernmost part of the U.S. before the effects of the first
- bomb could make themselves felt, it could also explain the "Mandan
- Milk Mystery"--the inexplicably high strontium 90 content of the milk
- collected at Mandan, North Dakota, by the AEC's New York Health and
- Safety Laboratory throughout the 1950s. For the radioactive particles
- from the Hanford reactor in Washington would have largely passed over
- dry Idaho and Montana as they were blown by the prevailing westerly
- winds toward the wet eastern part of North Dakota where Mandan was
- located.
- There was also one other peculiarity in the computer-printed maps.
- Florida, South Carolina, and Oklahoma showed no increase in infant
- mortality during the five years following the test, even though they
- had been in the path of the fallout. Soon, however, when I received
- detailed weather maps from the U.S. Meteorological Records Center,
- this too fitted the hypothesis: During the week ending July 17, 1945,
- the heavy rains had missed these states. In fact, the weather map
- indicated that the rainfall for that week had been restricted mainly
- to a rather narrow zone, extending from Texas along the northern edge
- of the Gulf of Mexico and then up the Atlantic coast. About 90
- percent of the fallout is brought down by the rains, while only about
- 10 percent settles to the ground in dry air. This is why the zones of
- heaviest rainfall showed the sharpest increases. The {Weekly Weather
- and Crop Bulletin} summarized the rainfall situation as follows:
-
- Rainfall during the week was again limited mostly to sections
- east of the Rockies. Heavy 24-hour amounts occurred the
- forepart of the week in Northeastern Texas and coastal areas of
- Gulf States and the latter part of the period in most Atlantic
- States and the lower Lake region.
-
- And the summary ended: "Rain was light over the Central States and
- little or none occurred in the far west."
- The {Weather Bulletin} also made it clear why the effects of a
- single small bomb had been so serious. Referring to the rainfall, it
- added: "Haying continued in nearly all states with generally good to
- excellent yields."
- Thus, the fallout from Trinity, which was twenty to thirty times
- greater than the fallout from later similar-sized tests because the
- fireball touched the ground and created enormous amounts of
- radioactive soil and vaporized rock, was deposited on the fresh
- vegetables and hay being harvested that week. And so the intensely
- radioactive short-lived isotopes, as well as the long-lived strontium
- 90, quickly found their way into the milk and food and from there into
- the unborn children in their mothers' wombs.

-
- The Battle for Publication
-
-
-
-
- EARLY IN JANUARY of 1969, the article on fetal and infant mortality
- was returned by the editor of {Science}. This was the paper that had
- been discredited by Abelson in his phone conversation with the
- reporter Stuart Brown, before the paper had arrived in the offices of
- {Science}. Copies of three reviews were enclosed. Two were clearly
- written by individuals in the field of public health and statistics;
- these merely contained suggestions for certain changes that might make
- the case more complete. The third reviewer, however, was totally
- negative. This individual went into a detailed analysis of fallout
- and dose levels in the U.S., making eight references to internal AEC
- reports. The majority of these reports had been prepared by the staff
- of the AEC's Health and Safety Laboratory in New York, directed by
- John Harley, the man responsible for the classified fallout
- measurement at Troy.
- The argument used to discredit the paper in this review (and also
- in an article published by Harley in the {Quarterly Bulletin} of the
- AEC's Health and Safety Laboratory later that year) was this:
- According to the detailed measurements made by the AEC's laboratory,
- the highest levels of strontium 90 had actually been in Utah, Montana,
- Wyoming, South Dakota, and Nebraska, as well as in very small portions
- of Massachusetts and Rhode Island. On the other hand, the lowest
- levels were measured in the southern U.S., from southern California to
- Florida. This was just the opposite of what I had said in my paper.
- Harley therefore argued that since infant mortality had risen most in
- the southern United States to the east of Nevada and New Mexico, and
- least in the low-rainfall mountain states of the Southwest, it clearly
- could not be the fallout that was responsible.
- This was indeed a devastating argument, supported by a vast set of
- detailed measurements. Yet these measurements cited by Harley were in
- total disagreement with the measurements reported by the Public Health
- Service, which I had used in my paper. According to the Public Health
- Service, year after year the "wet" southern and eastern parts of the
- U.S. showed levels of strontium in the milk two, three, or even four
- times as high as in the dry western mountain states. The mystery was
- resolved a few months later when Dr. E. A. Martel, a former U.S. Air
- Force fallout specialist, told me the story of the gummed films.
- The technique that had been used by Harley's lab to measure the
- fallout involved the use of a sheet of plastic about a foot square,
- coated on one side with a sticky substance very much like that used on
- flypaper. These plastic squares were mounted on a stand with the
- gummed side facing upward so as to catch the fallout particles as they
- descended. Every few days the films were collected, and shipped to
- the laboratory, where the radioactivity was measured.
- In a detailed study later carried out by scientists at the Battelle
- Memorial Institute in Ohio, it was discovered that in the dry states
- of the west, the winds constantly picked up the radioactive dust again
- and again, so that the exposed gummed films, acting just like the
- flypaper in a room full of flies, ended up collecting much more
- radioactivity than was typical for the soil of the area. On the other
- hand, in the high-rainfall areas east of the Mississippi, the rains
- soaked the fallout deep into the soil and kept the dust levels low.
- Thus, by the early 1960s, it was widely realized that the so-called
- "gummed film" measurements of fallout had given levels much too high
- for the dry mountain states, and too low for the East and South. In
- fact, in the 1962 United Nations Report on Atomic Radiation, of which
- John Harley was one of the authors, there was a note from Harley on
- page 225 indicating that the "gummed film" procedure "may lead to an
- overestimate of the tropospheric fallout," the troposphere being the
- lower part of the atmosphere containing the clouds of rain and
- radioactive dust.
- Yet seven years later Harley used the "gummed film" measurements in
- his attempt to discredit my correlation of nuclear testing with the
- rises in infant mortality, writing that "fallout before 1954 was
- exactly the opposite of what was stated by Dr. Sternglass."
- A few days after the paper on infant mortality had been returned by
- {Science}, the paper on the leukemia rise in the Troy area was also
- returned with a note of rejection. It was the same story again. Two
- of the three enclosed reviews were clearly by public-health physicians
- and statisticians and were quite favorable. One of these reviewers,
- in fact, stated that "the comparability between past fallout and past
- irradiated cases is `impressive,'" while the other reviewer began with
- the statement: "The conclusion of this paper, if correct, is clearly
- a most important one." The third reviewer, however, was completely
- negative, and, exactly as in the case of the paper on infant
- mortality, there could be no doubt to which organization this third
- reviewer belonged. Almost word for word and point for point, the
- third review resembled a critique that had been sent to me a few
- months earlier by John Conway, Chief Counsel for the Joint Committee
- of Atomic Energy. And this critique had been sent to him by the AEC's
- Division of Biology and Medicine.
- Perhaps the most remarkable point made by the third reviewer, in
- view of my experience with the Health Department of the State of New
- York, was the following: After arguing that the data on Albany-Troy
- were "incomplete," the reviewer asserted that "Sternglass could obtain
- the missing data."
- And then, quite unexpectedly, less than a week after the two papers
- had been returned by {Science}, the following letter arrived:
-
- {Bulletin of the Atomic Scientists}
- A Journal of Science and Public Affairs
- Eugene Rabinowitch, Editor
-
- Dear Dr. Sternglass:
-
- The drawings which we have for some of the figures in your
- article on Infant and Fetal Mortality Increase in the U.S. are
- not dark enough to be printed. Could you send us the original
- drawings--or very clear, dark copies--for figures 1 and 3.
-
- Thank you for your assistance.
- Sincerely yours,
-
- Merry Selk
- Editorial Assistant
-
- I gradually realized that the {Bulletin} must have decided to publish
- the report I had sent to Dr. Rabinowitch merely for his information.
- As I later learned from the managing editor, Richard S. Lewis, in
- the face of strong reviewers' opinions both pro and con, it had been
- decided that the grave issues raised by my findings should be
- publicized and discussed as widely as possible, both by the scientific
- community and the general public. This was indeed good news. For
- although {Science} had a far wider circulation, the {Bulletin} reached
- an important group of physical and political scientists in university
- and government circles around the world. Furthermore, like {Science},
- it was carefully read behind the Iron Curtain, hundreds of copies of
- each issue being sent to the Soviet Union, Poland, East Germany,
- Czechoslovakia, and Rumania.
- Subsequently, I presented all the new evidence before a meeting of
- the National Council of the Federation of American Scientists, and the
- Council voted to set up a special committee to look into the evidence
- in detail. Dr. John T. Edsall, a noted biologist at Harvard
- University, agreed to head up the study committee, and after many
- months of investigations during which he consulted a number of
- specialists, he indicated in a letter that he would personally be
- willing to urge the editor of {Science} to reconsider his decision not
- to publish my findings.
- Meanwhile, at the suggestion of a mutual acquaintance, I sent
- copies of my data to Dr. Luis Alvarez, then president of the Physical
- Society, who was now heading a physics research group in Berkeley,
- California. I included the maps showing increases in infant mortality
- downwind from the Trinity test site in New Mexico, for it had been
- Alvarez who watched the mushroom cloud from the first atomic explosion
- drift off across the United States. Thus, he was one of the few
- individuals in the world who had firsthand knowledge of the way the
- cloud had broken up and the directions in which it had drifted.
- In the first paragraph of the reply I soon received from him, he
- stated that he had found the evidence "very impressive, particularly
- the map of the United States with the percent excess in mortality
- showing an effect only downwind of the Trinity site." He added that
- "in view of the enormous statistical significance of the results you
- plot on your map of the United States it is difficult to question your
- findings."
- My article appeared in the April 1969 issue of the {Bulletin}.
- Interestingly, the managing editor, Richard Lewis, later told me that
- pressure had come both before and after publication in the form of
- long-distance calls from Washington from individuals who claimed to be
- long-term government friends of the journal. They said it was a grave
- mistake for the {Bulletin} to publish my article. When Lewis asked
- their names, they refused to identify themselves.
- The April issue also carried an article by Dr. Freeman J. Dyson, a
- theoretical physicist at the Institute for Advanced Studies in
- Princeton, entitled "A Case for Missile Defense." It was clear that
- the basic premise of Dyson's argument in favor of an antiballistic
- missile (ABM) system would not be valid if my conclusions on the
- vulnerability of the developing infant to radiation were correct. His
- basic assumption was that a defensive system, once installed,
- regardless of how really effective it might be, would force an
- attacker to concentrate many of his missiles on a few defended cities,
- thereby reducing the number of cities that could be attacked with a
- given number of missiles and saving those cities that could not be
- attacked. But in the process, the "saved" cities would be inundated
- with intensive fallout.
- I wrote a short note in rebuttal to Dyson's article, hoping that it
- would be published in the {Bulletin}. A few weeks later, a letter
- arrived from the {Bulletin} containing galley proofs of my letter and
- a reply by Dyson that began as follows:
-
- I welcome this chance to call attention to Ernest Sternglass'
- article "Infant Mortality and Nuclear Tests" in the April
- {Bulletin}. I urge everyone to read it. Compared with the
- issues Sternglass has raised, my arguments about missile defense
- are quite insignificant.
- Sternglass displays evidence that the effect of fallout in
- killing babies is about a hundred times greater than has been
- generally supposed. The evidence is not sufficient to prove
- Sternglass is right. The essential point is that Sternglass may
- be right. The margin of uncertainty in the effects of worldwide
- fallout is so large that we have no justification for dismissing
- Sternglass' numbers as fantastic.
- If Sternglass' numbers are right, as I believe they well may
- be, then he has a good argument against missile defense. . . .
-
- Thus it appeared that once the evidence on the dangers of worldwide
- fallout was allowed to reach the scientific community at large,
- responsible scientists would be willing to reconsider their past
- judgments.

- Counterattack at Hanford
-
-
-
-
- IN MAY 1969, for the first time in over fifteen years, as a result of
- growing concern among radiobiologists, there was to be a symposium
- dedicated to the effects of radiation on the developing mammal,
- including the human infant, both prior to and immediately after birth.
- Not since the detonation of the first hydrogen bombs in 1953 had
- such a conference been sponsored by the Atomic Energy Commission. In
- the ensuing years, a vast amount of data had been accumulated on the
- biological effects of radiation given to animals at doses comparable
- to those that would be expected in a nuclear war. But even by 1969,
- almost nothing had been published on the more subtle effects of lower
- radiation doses, comparable to those from fallout, given over long
- periods of time. And there still had been no publication of any
- largescale statistical studies of populations exposed to fallout.
- It was true that the AEC had initiated a large-scale statistical
- study of some 20,000 persons exposed to long-term, low-level radiation
- in AEC laboratories. But the study population included only adults in
- their period of least sensitivity to radiation, receiving the best
- medical care available, and working under carefully controlled and
- monitored conditions designed to minimize any chance of absorbing
- isotopes into their bodies. Since the control population consisted of
- individuals in the same families, communities, and installations who
- were not exposed to the radiation in the plant but who consumed the
- same fallout-contaminated food and inhaled the same fallout particles
- as the exposed test population, no effects from the fallout in the
- environment could in principle be detected by this study. More
- important, the study population did not include the children of the
- radiation laboratory workers. There was no search for unusual rises
- in stillbirths, infant deaths, congenital malformations, or cancer
- deaths among these children. When I inquired as to why this type of
- information was not sought, I was told that it was left out on the
- grounds that such questions might unduly alarm AEC employees.
- There was clearly no need for the AEC to restrict its studies to so
- limited a population. In 1966 large statistical studies had been
- published regarding the very small amount of naturally occurring
- radium in drinking water in the states of Iowa and Illinois. In these
- studies a definite increase in bone cancer had been observed for the
- areas with high radium levels, clearly suggesting that the effects of
- very low levels of longterm radiation on large populations could in
- fact be detected, and, furthermore, that there was no evidence for a
- safe threshold even at the doses received from natural background
- radiation.
- A letter from the Surgeon General of the United States, Dr. Jesse
- L. Steinfeld, to Representative William S. Moorhead of Pittsburgh made
- it clear that no large-scale epidemiological studies of possible low-
- level fallout effects were ever carried out or published by either the
- AEC or the U.S. Public Health Service, despite the fact that such
- studies had been specifically requested by congressmen Holifield and
- Price in the course of the 1963 congressional hearings and then
- promised by the Surgeon General then in office, Luther L. Terry. The
- exact words used by the present Surgeon General, Steinfeld, were:
-
- . . . studies to determine the feasibility of a national program to
- analyze morbidity and mortality data of thyroid cancer, leukemia,
- and congenital malformations in relation to radiation exposure led
- to the decision that a national program was not indicated.
-
- The letter added that "the feasibility studies were not published,"
- and ended with the following statement:
-
- Some effects on human populations from levels of radiation of
- the magnitude encountered during nuclear warfare or from direct
- high-level radiation therapy have been well established.
- Effects from low-level radiation have not been as clearly
- delineated and further research into these problems is needed.
- The Service welcomes the opportunity to work with those who
- desire to construct and execute scientifically based plans for
- studies of human effects from low-level radiation exposure.
-
- Thus, in all the years since 1963 no large-scale study of the
- effects of low-level radiation from *fallout* had evidently been
- undertaken.
- The Surgeon General's letter did say that studies of fallout-
- exposed schoolchildren in Utah were being conducted by Dr. G. D.
- Carlyle Thompson of the Utah State Department of Health and that Dr.
- Thompson had published some preliminary data on thyroid cancers among
- these children in the October 1967 {American Journal of Public
- Health}. "Progress reports to date," wrote Surgeon General Steinfeld,
- "show no unusual increased incidence of leukemia and no cases of
- thyroid cancer among children who reside in the selected `exposed'
- area of Utah-Nevada."
- Examination of Thompson's article, however, showed that, although
- Steinfeld's statement as phrased was literally true, it was misleading
- in its implication. For although Thompson's paper indeed indicated no
- increase in thyroid cancers in these children relative to their
- counterparts in New York State when both sexes were combined, there
- was in fact a significant increase among girls zero to 19 years of
- age. Among this group there was a total of ten cases for 1958-62, as
- compared to four cases expected. For young women aged 20 to 29 years
- old, the number was twenty as compared to nine expected. Still more
- significant, the rate of thyroid cancers per 100,000 young women under
- age 30 in Utah had increased almost 400 percent--from 0.6 in 1948-52,
- before the Nevada tests, to 2.3 in 1958-62.
- Since no figures on leukemia deaths in Utah were given in
- Thompson's article, it was necessary to consult the U.S. Vital
- Statistics, and what they showed was quite unbelievable. For the age
- group 5 to 14 years, there were large percentage rises in leukemia
- deaths exactly three to five years after each of the major test series
- that deposited fallout in the Utah area. Between 1949 and 1967, the
- annual number had increased four-fold in successive peaks from 1.5 to
- 6.2 per 100,000 children. But since leukemia rates for children 5 to
- 14 years in New York State and elsewhere also went up when fallout
- became widespread, although not as much as in Utah, a statistician
- could perhaps say that there was "no unusual increase of leukemia" in
- Utah.
- This, then, was the situation in May 1969 on the eve of the Hanford
- conference. According to the preliminary program of the symposium,
- Dr. Alice Stewart would be present. The conference was to take place
- at Hanford, Washington, the site where the plutonium for the Trinity
- bomb had been produced in 1944. A few days before I was scheduled to
- leave for Hanford, I watched the computer print out map after map of
- rising infant mortality stretching eastward from the Hanford reactors
- and from the Trinity site at Alamogordo, New Mexico.
- At about this time, a completely unexpected letter arrived by
- special delivery from the New York State Health Department's Bureau of
- Cancer Control:
-
- April 30, 1969
-
- Dear Dr. Sternglass:
-
- Doctor James Yamazaki of the University of California School of
- Medicine has written to me about your approaching presentation
- at the Ninth Annual Hanford Biology Symposium. In his letter,
- Doctor Yamazaki requested information about environmental
- factors in the Albany-Schenectady-Rensselaer country areas in
- the early 1950s. As you can see from my response, a copy of
- which is enclosed, this Bureau has reviewed some of the data
- upon which your June 1968 presentation in Denver was based. The
- results of this preliminary analysis are noted in the letter to
- Doctor Yamazaki. It is my opinion these data are too inaccurate
- for the type of analysis you have done. We are planning to
- restudy this subject and would be happy to have you take part.
-
- I hope this reaches you before the May 5th conference.
-
- Sincerely yours,
- Peter Greenwald, M.D.
- Director
- Bureau of Cancer Control
-
- The enclosed letter which Greenwald had written to Yamazaki
- indicated that J. H. Lade of the New York State Health Department had
- apparently made some errors in his data on leukemia in Albany-Troy,
- published years before in {Science} in the attempt to prove that there
- had been no effect from the fallout of April 1953. As Greenwald put
- it, "While it is unfortunate that this Health Department may have
- erred in not clearly describing the possible inaccuracies in this
- table it is clear that they should now be pointed out." Upon
- examining Greenwald's revised table, I discovered a remarkable
- coincidence: These newly found inaccuracies concerned only the cases
- born in 1953, the year the fallout arrived. Greenwald's new figures
- showed a greatly reduced number of leukemia cases in that year, thus
- making it now possible to argue that there had been no significant
- effect from the fallout.
- At the end of Greenwald's letter was the notation:
-
- cc: Dr. Sternglass
- Dr. Sagan
-
- And on the preliminary program of the Hanford meeting, listed below my
- name, was:
-
- 9:40 P.M. INVITED DISCUSSANT
- L. A. Sagan
- Palo Alto Medical Clinic
-
- This was Dr. Leonard Sagan, who had long been working for the AEC's
- Division of Biology and Medicine. He was apparently scheduled to be
- discussant, or critic, for my paper at Hanford. Why was he listed as
- being affiliated only with the Palo Alto Medical Clinic?
- Interestingly, my paper was the only one in that session for which a
- discussant had been listed in the final program. The co-chairman of
- the session was Dr. J. N. Yamazaki of the University of California,
- the same individual who had just requested information on the Troy
- rainout from the New York State Health Department. Dr. Yamazaki had
- published a number of papers while working for the Atomic Bomb
- Casualty Commission that argued for the absence of significant
- leukemia rises among offspring born to the survivors of Hiroshima.
- Upon arriving at Hanford, I was interested to discover the summary
- of a paper written by Dr. Y. I. Moskalev and his colleagues at the
- Institute for Biophysics in Moscow. This group of Russian scientists
- had studied the effects of low-level radiation--of the type produced
- by fallout--from strontium 90 and other isotopes when given to various
- animals before and during pregnancy. Their observations on the
- offspring of all types of animals, ranging in size from rats, rabbits,
- and dogs to sheep and cows, appeared to show effects similar to those
- I had postulated for human infants. There was no spectacular increase
- in gross malformations at low levels of strontium 90. Instead there
- was a small reduction in weight at birth, a decline in fertility, and
- an increase in the number of fetal deaths. And the earlier the
- radioactivity was fed to the pregnant animals, the more pronounced
- were the effects, just exactly as the studies of diagnostic X-rays
- given during pregnancy had indicated in the case of humans.
- Unexpected difficulties, however, developed, and the Russian
- scientists were unable to attend. This was a great disappointment,
- for the studies of Dr. Moskalev and his group were the first published
- work I was aware of that appeared to offer the kind of crucial
- laboratory confirmation of the statistical evidence for the damaging
- effects of fallout on the newborn.
- Early in the conference, however, other evidence was presented, in
- session after session, that internal radiation from isotopes of the
- type that occurred in fallout was particularly hazardous to the ova
- and the early embryo and fetus. These were levels much lower than
- those that led to lethal effects in mature animals.
- First on the program on the evening my paper was scheduled was a
- paper by Dr. M. L. Griem of the University of Chicago School of
- Medicine. Dr. Griem indicated that in his careful study of children
- X-rayed while in the womb there was no evidence for a difference in
- the number of leukemia cases between the irradiated children and the
- two control groups who had not received any radiation. But as soon as
- Dr. Griem had begun his talk, it became apparent that the number of
- children X-rayed was only 1008, a group in which one would normally
- not expect more than one case of leukemia in ten years of life. Thus,
- even a doubling would at most result in one extra leukemia case,
- clearly too small an effect to be readily observed with any
- statistical certainty. As Dr. Alice Stewart herself pointed out in
- the ensuing discussion, "the reality of juvenile leukemia is such that
- no one could hope to do a followup like this and detect an increase of
- 50 percent of the normal incidence without being prepared to follow
- out 900,000 children for ten years, and no one has done that." She
- herself had to interview the families of over 7000 children who had
- died of cancer out of a total of nearly nineteen million children born
- in order to establish a clear causal connection.
- Interestingly, however, Dr. Griem's study actually lent support to
- the hypothesis of other effects from low-dose radiation, even in so
- small a study population as 1008 children. His data showed that,
- although there was no detectable increase in leukemia, there was a
- significant increase in benign tumors and certain types of congenital
- birth defects, especially severely disfiguring birthmarks.
- Furthermore, Griem's study revealed that stillbirths had nearly
- doubled--from eight and nine cases in the two control groups to
- sixteen among those who had received X-rays in the womb. And
- according to Griem, the X-rays were given mainly in the less sensitive
- second and third trimesters of pregnancy, with doses of only 1 to 3
- rads to the fetuses. But Dr. Stewart had found the sensitivity to be
- some ten times greater in the first three months of pregnancy. Thus,
- Griem's study indicated that if the X-rays had instead been given in
- the earliest developmental phase, a dose only about one-tenth as
- large, or a mere 100 to 300 millirads, would have produced a doubling
- of stillbirths and genetic defects. These were, in fact, the general
- doses that had been received by large numbers of unborn children from
- fallout. So Griem's study actually provided, for the first time,
- direct observational evidence in humans for my statistical findings on
- fetal mortality.
- Soon it was Dr. Stewart's turn. As her opening paragraph made
- clear, it was the opposition to her findings that drove her to find
- more and more convincing evidence:
-
- More than ten years ago, a retrospective approach to the problem
- of cancer etiology led to the conclusion that about one in
- twenty of the 600 cancer deaths that were taking yearly tolls of
- the seven million children living in Britain were being caused
- by obstetric X-ray examinations. So far as the investigators
- themselves were concerned, the matter would probably have rested
- there had it not been for the general skepticism that greeted
- this suggestion.
- However, so many clinicians and experimentalists refused to
- accept the necessarily epidemiological evidence that it was
- finally decided to remove all grounds for doubt by isolating
- groups of mainly radiogenic cases (i.e. X-rayed cases) and
- wholly non-radiogenic cases (i.e. non X-rayed cases) and
- observing the ages of the two groups of children when symptoms
- developed.
-
- She then went on to present new evidence that leukemia cases among
- children X-rayed while in the womb showed a clearly recognizable,
- narrow age range of between three and five years after birth, evidence
- that supported the hypothesis that the excess cases in Albany-Troy
- among the children irradiated in the womb were caused by radiation,
- since they too showed the same abnormal pattern of age at death.
- Dr. Stewart also observed that all types of cellular defects
- produced by radiation "were felt with equal force by all systems and
- organs" in the fetal stage, a point crucial in explaining how
- radiation could cause subtle types of damage that would lead to such
- biochemical defects as the inability to resist infections early in
- infancy or childhood. And in her conclusion, she pointed out that her
- evidence clearly showed that the effects that prove fatal before the
- age of 10 years are mainly initiated before birth, and often in the
- most sensitive period of early development. Thus Dr. Stewart's paper
- had greatly strengthened my statistical findings on the effect of
- fallout radiation.
- I then presented my evidence, concluding with the estimate that
- some 400,000 infants of less than one year of age probably had died as
- the result of nuclear fallout between 1950 and 1965. The chairman
- then announced that there would be no discussion until Dr. Sagan of
- the Palo Alto Medical Clinic had commented on the paper. Dr. Sagan
- took the microphone.
- He began by showing the slides of the material collected for him by
- the co-chairman of the session, Dr. Yamazaki, from the New York State
- Health Department. Sagan made the point that the data were too
- unreliable for the type of study I had done. He next cited an
- estimated figure for the expected number of leukemia cases in a
- population exposed to a radiation dose of 1 rad, namely one case per
- year among each million persons. Therefore, he concluded, the doses
- in the Troy area, with its 130,000 children, were some 1000 times too
- small to produce even a single extra leukemia case. Sagan's estimated
- figure, however, was the one for the mature adult, who is least
- sensitive of all to radiation. It was evident from Dr. Stewart's and
- Dr. MacMahon's work, as well as from the paper just delivered by
- Griem, that the fetus and especially the early embryo were many
- hundreds of times as sensitive as the adult. Furthermore, the total
- dose from internal radiation in Troy was at least five times the
- external dose measured by the AEC's Health and Safety Laboratory--
- which Sagan had used in his argument.
- He next cited Harley's invalidated "gummed film" fallout
- measurements to discredit any association of fallout with the infant
- mortality rises in the wet areas of the South and East. He did this
- despite the fact that the Public Health Service's data for strontium
- in the milk that I had just presented correlated perfectly with the
- changes in infant mortality in every state for which the Service had
- published data.
- The discussion was then opened to the floor, and a long and often
- heated debate began. Some AEC scientists had slides that showed that
- miniature swine fed fairly large doses of strontium did not seem to
- show detectable reductions in weight and litter size. This was in
- apparent contradiction to the findings of Moskalev, who was
- unfortunately not present to defend his work. But then Dr. T. K.
- Ellis of the University of Utah reported that in beagle dogs given
- small amounts of strontium 90, surprisingly strong effects on male
- hormone production had been found, as well as changes in reproductive
- cells. Dr. Harold Rosenthal, who had made measurements on baby teeth
- collected from all over the United States, indicated that for Texas,
- St. Louis, Toronto, Detroit, Chicago, and California he had found a
- close correlation between levels of strontium in the teeth and the
- levels reported for the milk. This showed that the Public Health
- Service's milk measurements that I used in my work were indeed a good
- indication of the amount of exposure received by infants in various
- areas.
- The evidence supporting unexpectedly severe effects on the early
- embryo and fetus from internal radiation sources continued to
- accumulate until the close of the conference. And afterward, when I
- was able to examine the original manuscript submitted by Dr. Moskalev,
- I found that his studies did in fact confirm the most crucial points
- at issue in the whole fallout controversy. His group had found that
- when various of the isotopes contained in fallout were fed to female
- animals during pregnancy, large fractions were transferred through the
- placenta to the developing fetus. For example, up to 38 percent was
- transferred in the case of strontium given to rats and up to 66
- percent in the case of cesium given to a litter of dogs. Furthermore,
- the amounts reaching the developing fetus were many times greater for
- continuous, slow intake (such as occurs with fallout in food) than for
- a large single dose.
- More significant, Moskalev had found a direct relationship between
- the size of the doses of isotopes given just before pregnancy and the
- percent of the offspring that died--even for doses as small as 4-
- billionths of a curie per gram of body weight. This dose was well
- within the range of doses from fallout delivered to the early human
- fetus by the accumulated strontium in the mothers' bones. Thus, the
- argument that there might not be any effects at all from long-term,
- low-level radiation as opposed to doses given all at once, like
- diagnostic X-rays, had now been disproven by direct experiments.
- Moskalev's results also showed that, regardless of whether a given
- amount of isotopes was fed to a mouse weighing 20 grams or to a dog
- weighing many thousands of grams, approximately the same fraction of
- the total amount would always concentrate in the rapidly growing
- embryo. This was one reason why, in all species, the fetus was so
- much more sensitive to fallout radiation than the adult. A given tiny
- amount of an isotope in the body of an adult might be quite tolerable
- if it was evenly distributed throughout the 70,000 grams of an average
- woman's body weight. But if even only one one-hundredth of this
- amount in the mother's body goes to the embryo during the first two to
- four weeks of development, when the embryo weighs less than a
- hundredth of a gram, then the concentration of radioactivity in the
- embryonic tissue would be the same as if the entire original amount
- had been given to a 1-gram embryo. Instead of the relatively minor
- radiation dose produced by this original amount distributed in the
- 70,000 grams of body weight typical of the adult, there would be a
- concentration 70,000 times greater in the early embryo. And added to
- this was the fact that the embryo was already hundreds of times more
- likely to develop cancer or other forms of biochemical damage than the
- much more resistant, fully mature adult, as paper after paper
- presented at the conference showed. Thus, the low external doses
- given by fallout to the body of an adult, doses on which the world's
- radiation protection agencies had based their assumption that fallout
- was harmless, were actually highly lethal doses for the early embryo.
- It was not our physics and technology that had been inadequate, but
- our knowledge of biological systems and their enormous ability to
- concentrate toxic agents. Just as in the case of DDT, it was not the
- amount distributed throughout the environment that was so serious. It
- was the selective concentration in the food chain and then in the
- newly forming organs of the rapidly developing young embryo. Since
- all higher animals, including man, must pass through this critically
- sensitive phase, it was clear that, unless the problem was widely
- recognized and acted upon, man could extinguish himself and all other
- animals, not through the effect of radiation on the adult, but through
- the effect on the weakest link in the chain of life--the unborn and
- the very young.
