- The Unheeded Warning
-
-
-
-
- THE TROY INCIDENT was easily forgotten because, at the time, little
- was known about the effects of low-level radiation--either from
- fallout or from other sources. The subject had hardly even been
- thought about. Scientists generally assumed that such levels were
- harmless, since they produced no immediately observable effects.
- During the next few years, however, tremendously improved radiation
- measurement techniques coupled with detailed laboratory studies
- revealed many previously unsuspected hazards from fallout. And with
- these discoveries, the forgotten incident in upstate New York re-
- emerged and took on great significance.
- By 1953, it was already known that many of the radioactive elements
- (called isotopes) created by an atomic explosion, once they entered
- the atmosphere in the form of tiny fallout particles, would
- contaminate food, water, and air and thus find their way into the
- human body. What was not widely known, however, was the extent to
- which these isotopes became concentrated in various body organs.
- Inside the body, they behaved just like their nonradioactive natural
- counterparts. The isotope strontium, for instance, which is similar
- to calcium, settled in bones and teeth. Radioactive iodine behaved
- like regular iodine, seeking out and concentrating in the thyroid
- gland, an organ which is vital in regulating the growth and
- functioning of the human body.
- It was in the case of iodine that some of the most alarming
- discoveries were made. In the early 1950s researchers found that
- iodine became concentrated in the milk of cows that grazed on pasture
- contaminated with fallout. When people drank the milk, the iodine
- began building up rapidly in their thyroid glands. Since the thyroid
- gland is small in size, the concentration was very heavy.
- Measurements revealed that in any given situation the radiation dose
- to the adult thyroid would be as much as a hundred times the external
- dose from the fallout in the outside environment. But far more
- important were the results of extensive studies conducted at the
- University of Michigan and published in 1960. These showed that the
- radiation dose to the thyroids of unborn children and infants was ten
- to one hundred times higher than that to the adult because of the
- greater concentration in the smaller thyroids. This discovery held
- serious implications for the health of the children of Troy. It meant
- that the doses to their thyroids might have been as much as a hundred
- to a thousand times higher than those estimated by Dr. Clark and the
- AEC scientists, who had only considered the overall dose from the
- fallout in the external environment.
- However, by the time these discoveries became widely known, a
- voluntary halt in atmospheric testing had been agreed upon by the
- Soviet Union, the United States, and Great Britain, and there was
- considerable hope that incidents of heavy fallout would never occur
- again. Thus it seemed less urgent to pursue investigations into the
- problem. But in 1961, during the Berlin crisis, Russia's detonation
- of a 100-megaton hydrogen bomb high over Siberia marked the resumption
- of large-scale atmospheric testing by the nuclear powers, and the
- levels of radioactivity in air and water once again rose sharply
- throughout the world. In the weeks that followed, an enormous peak of
- radioactive iodine was detected in milk throughout the northern
- hemisphere. As the testing continued, many scientists began to feel
- it was imperative to find a conclusive answer to the question: Just
- exactly how harmful was low-level radiation from fallout?
- It was in this context that the well-known nuclear physicist Ralph
- Lapp wrote an article for {Science} magazine in 1962 which first
- focused attention on the significance of the Albany-Troy incident.
- Lapp's article showed that radiation doses far larger than those
- permitted by federal safety guidelines must have been received by the
- children of Troy and numerous other cities that had been subjected to
- similar "rainouts" in the early years of testing. The purpose of the
- article was to point out that the Troy incident provided an excellent
- opportunity to find out just what the effects of fallout were. The
- surrounding area's population of half a million persons was large
- enough to insure that any increase in the normally low incidence of
- such radiation-caused diseases as thyroid cancer or childhood leukemia
- would show up. (The normal incidence of leukemia among children under
- ten years old was about two to three cases per year per 100,000
- children. Thus, if any area with only a few thousand children were
- studied, no cases at all might be found in some years, even if the
- radiation were strong enough to double the normal expected number.)
- And the detailed radiation measurements taken by Dr. Clark's students
- and the AEC meant that relatively accurate estimates could be made of
- the doses involved.
- The study that Lapp proposed had enormous potential ramifications.
- At the time, many people in government, military, and scientific
- circles still believed that mankind could survive the levels of
- fallout that would result from a nuclear war, levels thousands of
- times greater than those from peacetime testing. The United States
- had embarked on an extensive civil-defense program based on this
- belief. But if it were shown that peacetime fallout levels led to a
- significant increase in fatal diseases, then by implication, nuclear
- war would probably mean the end of mankind, and thus the vast nuclear
- war machinery developed by the United States and the Soviet Union
- would become useless. In the second place, if it were shown that
- large numbers of children had already died from the effects of
- fallout, then tremendous public revulsion would probably be generated
- against *all* activities that released more radioactivity into the
- environment. These would include not just the testing of nuclear
- weapons, but also the monumental program planned by many governments
- and industries throughout the world for the peacetime uses of atomic
- energy. For nuclear power reactors, atomic gas-mining explosions, and
- other forms of nuclear engineering all normally release low levels of
- radioactivity and, in the event of an accident, they entail the risk
- of much worse. And, finally, those individuals who had been in
- positions of responsibility would have a terrible guilt to bear for
- the damage already done.
- The appearance of Lapp's article also served to highlight another
- extraordinary fact. It was then seventeen years since the first
- atomic explosion at Hiroshima in 1945, yet no large-scale cancer
- studies such as he proposed had ever been carried out, even though the
- AEC had long been in possession of detailed fallout data for many
- areas of the U.S. A great deal of information existed on the effects
- of high doses of radiation, such as those received by the survivors of
- the explosions at Hiroshima and Nagasaki, but there was no real
- evidence regarding low-level effects, either from laboratory animal
- studies or from direct observations of large human populations. The
- lack of animal studies was somewhat understandable, since no such
- experiments could be carried out at the extremely low doses produced
- by fallout without requiring hundreds of thousands or even millions of
- animals and many years to detect the small increases of a rare disease
- such as leukemia. But in the case of humans, such a large study
- population had already been created by the fallout from years of
- atomic testing. Yet the AEC had ignored this opportunity to resolve
- such an important issue. Thus, those who wished to minimize the
- danger of continued atomic testing could argue, in the absence of data
- to the contrary, that long-term, low-level exposure such as that from
- fallout had not been proven to increase fatal diseases.
- The absence of such studies was all the more striking because there
- were already strong indications that such danger existed. It was
- toward the end of 1955 that Dr. Alice Stewart, head of the Department
- of Preventive Medicine at Oxford University, first became aware of a
- sharp rise in leukemia among young children in England. A young
- statistician in her department, David Hewitt, had discovered that the
- number of children dying of this cancer of the blood had risen over 50
- percent in only a few years. In the United States an increase about
- twice as large had occurred. One aspect of this rise was extremely
- puzzling: The leukemia seemed to strike mostly children over two to
- three years of age--there was little or no increase for younger
- children. This had not been the situation prior to World War II, when
- both groups had shown a parallel, much more gradual rise. The
- question was: What new postwar development could be responsible for
- the increase in deaths among the older children?
- Dr. Stewart undertook a study to find out. With the assistance of
- health officers throughout England and Wales, she obtained detailed
- interviews with the mothers of all of the 1694 children in those
- countries who had died of cancer in the years 1953 to 1955, as well as
- with an equal number of mothers of healthy children. By May 1957, the
- analysis of 1299 cases, half of which involved leukemia and the rest
- mainly brain and kidney tumors, had been completed. The data showed
- that babies born of mothers who had a series of X-rays of the pelvic
- region during pregnancy were nearly twice as likely to develop
- leukemia or another form of cancer, as those born of mothers who had
- not been X-rayed. As Dr. Stewart noted, the chance of finding such a
- two-to-one ratio purely as a result of statistical accident was in
- this case less than one in ten million. Thus, in the paper she
- published in June 1958, Dr. Stewart concluded that the dose from
- diagnostic X-rays could produce a clearly detectable increase in
- childhood cancer when given during pregnancy.
- This was an extremely low dose. It was roughly comparable to the
- dose that most people receive in only a few years from natural
- background radiation. (Mankind has always lived with a "natural
- background" of radiation, produced by cosmic rays and various
- naturally occurring radioactive substances. The annual dose from the
- radiation averages about 100 millirads.) But still more significant,
- this dose was comparable with what the pregnant mothers of Albany-Troy
- must have received from the fallout of the "Simon" test in 1953.
- In this connection, there was another finding of Dr. Stewart's
- study that was even more disturbing. This concerned the timing of the
- X-rays. Children whose mothers were X-rayed during the first third of
- their pregnancy were found to be some ten times more likely to develop
- cancer than those whose mothers were X-rayed toward the end of
- pregnancy. In other words, the earlier the worse. This finding had
- much more serious implications for fallout than for medical X-rays.
- Almost 90 percent of pelvic X-ray examinations occur shortly before
- delivery time, but since fallout comes down indiscriminately on whole
- populations, it irradiates unborn children at all stages of
- development, including the earliest. The fallout hazard was further
- compounded by the tendency of various radioactive elements, such as
- iodine and strontium, to concentrate in vital body organs. This meant
- that the doses to the thyroids and bone marrows of unborn children
- from fallout could be many times higher than the doses received from
- diagnostic X-rays by the children in Dr. Stewart's study, which had
- already nearly doubled the cancer incidence.
- But in order to establish a clear cause-and-effect relationship
- between the X-rays and the additional cancer deaths, there had to be a
- direct relationship between the amount of radiation received by the
- fetus and the chance that the child would develop cancer a few years
- later. And indeed, when Dr. Stewart and David Hewitt examined the
- available records for the number of X-ray films taken, they found that
- there were distinctly fewer cancer cases among the children whose
- mothers had only one X-ray than among those who had four or more. The
- number of cases where this information was available was too small to
- establish a conclusive connection between dose and cancer risk, but
- there was other evidence that supported this general trend. For
- example, whenever the X-rays had been taken only of other parts of the
- body, such as the arms and legs, so that only a small quantity of
- scattered radiation reached the unborn child in the womb, the increase
- in cancer risk was only about one-fifth as great as in those cases
- where the abdominal region itself was X-rayed.
- These latter observations were in direct contradiction to a belief
- that was essential to the continuation of all programs for nuclear
- testing and the peaceful uses of the atom--namely, the so-called
- "threshold" theory. This theory held that there was a certain low
- level of radiation exposure, a "threshold," below which no damage
- would be caused. If this threshold was about the same as the yearly
- dose from background radiation or from exposure to typical diagnostic
- X-rays, as various supporters of nuclear programs maintained it was,
- then there would theoretically be no ill effects from past or present
- weapons tests, from the radioactive releases of nuclear reactors, or
- even from the radiation persisting after a nuclear war, since this
- radiation would probably not exceed the threshold if it were averaged
- out over a lifetime. But Dr. Stewart's study implied that if there
- were any safe threshold for unborn children and infants it would have
- to be less than the dose from a single X-ray picture. And her finding
- that the risk of cancer seemed to be directly related to the size of
- the dose suggested that there might not be any safe threshold at all,
- and that *any* increase in radiation exposure might produce a
- corresponding increase in the risk. Even if the risk for a certain
- tiny amount of radiation was extremely small, say, one chance in ten
- thousand, then if millions of people were exposed to this radiation,
- hundreds would be likely to get cancer. Fallout had already exposed
- millions of people to doses comparable to those received by the
- children in Dr. Stewart's study, and the proliferation of nuclear
- explosions for peaceful purposes would make this exposure even more
- extensive.
- There was widespread refusal to accept the implications of Dr.
- Stewart's work. Her findings were regarded as doubtful for such
- reasons as their dependence on the memories of the mothers as to the
- number of X-ray exposures received. Other studies were cited that
- showed no effects from X-rays. It was said that her study was
- inapplicable to fallout because it had been shown that a specified
- dose of radiation given all at once--as is the case with a diagnostic
- X-ray--is more damaging than the same total dose given gradually over
- a period of weeks, months, or years--as is the case with fallout.
- This argument opened up another important area of disagreement
- about radiation dangers. Were the cancer-causing effects of radiation
- cumulative? Or did body cells recover? There was no question that
- body cells did repair themselves in the case of such damage as
- radiation burns, which healed with the passage of time. Supporters of
- the threshold theory hypothesized that this would also hold true for
- cancer. This was another bulwark of the "threshold" theory, for, if
- such recovery did take place, then there would indeed exist a level of
- radiation low enough so that the body's repair mechanisms could keep
- pace with the damage.
- However, evidence was soon forthcoming that would refute the
- criticisms of Dr. Stewart's study and thereby cast further doubt on
- the validity of the threshold theory. After the publication of Dr.
- Stewart's results, Dr. Brian MacMahon of the School of Public Health
- at Harvard University undertook another study of the relationship
- between diagnostic X-rays and childhood cancer. He constructed this
- study so that there would be no question as to the number of X-rays
- given to the mothers. Using the carefully maintained hospital records
- of 700,000 mothers who delivered their babies in a series of large
- hospitals in the northeastern United States between 1947 and 1954, he
- compared the risk of cancer for the children of the 70,000 mothers who
- had received one or more X-rays with the risk for the children of the
- remaining 630,000 mothers who had received no X-rays during pregnancy.
- The results of his study, published in 1962, fully confirmed the
- findings of Dr. Stewart: There was a clear and highly significant
- increase in the risk of cancer for the children who had been X-rayed
- before birth, and, most important, the risk did indeed increase with
- the number of X-rays taken. The overall risk was somewhat smaller
- than had been found for the British children by Dr. Stewart, but this
- could easily be explained by the fact that the dose to the mothers in
- MacMahon's study from each X-ray picture was substantially lower than
- for those in Dr. Stewart's, due to improvements in X-ray technology.
- As for the studies cited by critics which did not show any increase in
- cancer risk from prenatal X-rays, it developed that these were all
- based on small study populations, and even then the indications were
- that if these results were carried out to larger numbers they would
- confirm Stewart and MacMahon.
- But there was still one major question that remained unanswered.
- To what degree were the effects of diagnostic X-rays comparable with
- those of fallout?
- There were already many indications that the effects might be
- similar. Among these was the fact that had prompted Dr. Stewart to
- undertake her study in the first place, namely, the evidence that in
- both the United States and England cancer and leukemia among school-
- age children had increased sharply beginning a few years after World
- War II. This was the period when nuclear fallout was first introduced
- into the atmosphere. And now, Dr. Stewart's and Dr. MacMahon's
- studies had served to point up the following significant aspects of
- this increase:
- First, the effects of X-rays, although very real, were not strong
- enough to have caused all of the very large general increase in
- childhood cancer, which ranged from 50 to 100 percent. Dr. Stewart
- herself estimated that X-rays could only have accounted for perhaps 5
- percent of this increase.
- Second, this general increase had taken place only among children
- older than two or three--exactly the age group that had suffered the
- greatest effects from X-rays. This suggested that some other form of
- radiation might be causing the unexplained portion of the increase,
- since the characteristic age at death was the same.
- Third, other possible factors such as the introduction of new
- drugs, pesticides, or food additives had been ruled out because these
- factors had been found to be essentially the same for the healthy and
- afflicted children alike.
- But the main reason why it seemed that fallout was at least as
- effective as X-rays in producing childhood cancer was the growing
- evidence for a direct relationship between the number of X-ray
- pictures taken and the risk of cancer. For if the risk increased with
- each additional picture, as the studies of Stewart and MacMahon
- indicated it did, then this clearly implied that there was no
- significant healing of the damage and thus that the cancer-causing
- effects of radiation were cumulative. This would mean that the
- effects of a dose received over a period of time from fallout would be
- similar to those from an equal dose received all at once from X-rays.
- Such a direct connection between the amount of radiation absorbed
- and the likelihood of cancer could be predicted on the basis of a
- theory developed by Dr. E. B. Lewis of the California Institute of
- Technology. According to Dr. Lewis, cancer could be triggered if one
- particle of radiation scored a single bulletlike hit on a crucial DNA
- molecule in the chromosomes of a cell. The DNA contains the genetic
- code that controls the functioning and reproduction of the cell. If
- it were damaged by a particle of radiation, this might disrupt the
- governing mechanism and cause the cell to begin the unlimited growth
- which characterizes cancer.
- The significance of this theory was twofold. First, it was already
- established that such damage to the DNA was one of the ways that
- radiation produced hereditary or genetic damage in the female ova and
- male sperm cells--the type of damage that results in malformations and
- other harmful mutations in offspring. What Dr. Lewis stated, however,
- was that it was exactly the same type of damage, but to the DNA of any
- body cell, that could produce cancer. This was extremely important
- because it had already been decisively demonstrated that genetic
- damage was cumulative. In one experiment after another, using fruit
- flies and large colonies of mice, it was found that it did not matter
- how slowly or quickly a given dose of radiation was administered--in
- every case the number of defective off-spring was essentially the
- same. The resulting effect on offspring was determined only by the
- total accumulated radiation dose received, regardless of the length of
- the time period over which it was given. There were some indications
- of repair in the ova of female mice, but the effect was relatively
- small at best. Thus there existed clear evidence that radiation
- effects of the type that produced genetic damage were cumulative,
- especially in the male sperm cell. But if Dr. Lewis was right, and
- radiation caused cancer in body cells in exactly the same way as it
- caused genetic damage in reproductive cells, then this clearly implied
- that the cancer-causing effect of radiation was also cumulative. And
- if this was so, then the greater the radiation dose, the greater the
- risk of cancer. Dr. Lewis's theory therefore supported the findings
- of Stewart and MacMahon, and simultaneously gave weight to the theory
- that the cancer-causing effects of protracted radiation from fallout
- would be the same as for X-rays given all at once.
- All of this evidence combined pointed toward a single tragic
- conclusion: Man, especially during the stage of early embryonic life,
- was hundreds or thousands of times more sensitive to radiation than
- anyone had ever suspected.

-
- A Small Error in the Assumptions
-
-
-
-
- MY OWN INVOLVEMENT in the subject of fallout hazards began in 1961.
- That was the year of the Berlin crisis, when the Soviet Union ended
- the voluntary moratorium on nuclear testing and the U.S. government
- called for a large-scale fallout shelter construction program. The
- intensified threat of nuclear war caused much concern in the
- scientific community, and in Pittsburgh, Pennsylvania, a group called
- the Federation of American Scientists, of which I was a member,
- decided to participate in a study of the chances for survival of a
- large industrial city like Pittsburgh in the event of a nuclear war.
- Since I was professionally involved in research on new techniques for
- reducing the radiation dose from medical X-rays, and therefore was
- interested in the problem of low-level radiation effects, it was
- suggested that I join the section investigating the health hazards
- from fallout.
- Almost as soon as we had begun our work, a disturbing fact emerged.
- All the calculations made by government agencies as to the radiation
- protection necessary after a full-scale nuclear war were based on the
- assumption that the adult could tolerate the enormous dose of 200 rads
- spread over a few days and as much as 1000 rads over a year.
- Apparently it had been decided by the government's scientific advisory
- groups that it was not necessary to take into account the long-range
- after-effects of radiation, either on the survivors themselves or on
- their offspring. Yet, as I well knew from my own research, the reason
- why so much effort was being spent to reduce the dose from medical X-
- rays was that the doses of only a few rads per year received by
- radiologists in the course of their work had been found to decrease
- their life spans significantly, while among their children there had
- been a definite increase in congenital defects. Furthermore, if Dr.
- Stewart was correct, only 1 to 2 rads would double the chances of a
- child developing cancer when the radiation was received in the last
- few months of the mother's pregnancy, and only one-tenth of this
- amount might have the same effect when received in the first few
- months. Exposed to the radiation levels that would be present in the
- aftermath of a nuclear war, then, a great many children born in the
- years following could be expected to die of leukemia, cancer, or
- congenital malformations before reaching maturity.
- Additionally, these doses of hundreds of rads that the government
- agencies considered tolerable were only estimates of the external
- doses from the fallout in the environment. The internal doses from
- the fallout particles concentrated inside the body, which would be
- hundreds or thousands of times higher still, had not even been taken
- into account, although the knowledge necessary for calculating these
- internal doses was widely available.
- It thus appeared that the chances for survival after a nuclear war
- were being presented to the public in a far more optimistic light than
- scientific evidence justified. And then, with the publication in 1962
- of Lapp's article in {Science}, revealing the extremely high internal
- doses received by the children of Albany-Troy from the 1953 rainout,
- it became evident that the same held true for the health effects of
- peacetime fallout. Since by 1962 the intensive nuclear testing was
- filling the rains all over the world with radioactivity approaching
- the amounts that had descended on Troy, the number of children that
- could be expected to die as a result was very large.
- I made an estimate as follows: According to figures presented at
- congressional hearings, the fallout from each 100 megatons* of
- hydrogen bombs tested would give an overall dose of from 200 to 400
- millirads to every man, woman, and child in Europe, North America, and
- Asia. This was approximately the total megatonnage of the bombs
- already exploded in the latest test series as of the end of 1962, and
- 200 to 400 millirads was roughly equivalent to the dose from a pelvic
- X-ray. Thus, if there were indeed no difference in the effects of
- diagnostic X-rays and fallout, one could expect as much as a 20
- percent increase in cancer rates for those children born within a year
- after the recent tests. Since, at the time, about one child in a
- thousand normally died of cancer before reaching adolescence, and
- since four million children were born in the United States each year,
- then every year some 4000 children normally developed cancer.
- Therefore, a 20 percent increase would mean close to 800 additional
- deaths in the United States alone. For the rest of the world, the
- figure would be perhaps ten times larger, all as a result of only the
- most recent atmospheric tests.
-
- * One megaton is the equivalent in explosive energy to a million tons
- of TNT.
-
- And these figures did not even take into account the probability of
- much larger doses from local rainouts, where the fallout was brought
- down in concentrated form. In the case of Troy, the type of
- calculations made by Lapp indicated that an overall dose of anywhere
- from a few hundred to a few thousand millirads must have been received
- by the unborn children in the area, equivalent to a whole series of
- pelvic X-rays. Depending on whether they were in an early or late
- stage of development at the time, their chances of developing cancer
- would have been increased 100 percent or more.
- Thus it was clearly of the greatest importance to see whether the
- number of leukemia deaths among the children of Troy had in fact begun
- to increase a few years after the fallout arrived. (A characteristic
- delay in the onset of the disease, when radiation was the cause, had
- been found by both Dr. Stewart and Dr. MacMahon and was also observed
- among the survivors of Hiroshima and Nagasaki, who began developing
- this fatal form of cancer some three to five years after their
- exposure.) Furthermore, it seemed imperative that the worldwide
- scientific community be made aware of the implications of the data of
- Stewart and MacMahon, and of the urgent need for large-scale
- statistical studies of populations exposed to fallout. Accordingly,
- by late fall 1962, I had completed an article on the subject and
- submitted it to {Science} magazine. This seemed the most appropriate
- place for publication, since it was the official journal of the
- American Association for the Advancement of Science (AAAS), the
- country's largest scientific professional association, and as such was
- read by a large, interdisciplinary audience of scientists throughout
- the world.
- This was, however, an inauspicious time for the publication of an
- article with such negative implications for nuclear warfare and
- peacetime testing. The Cuban missile crisis, which brought the world
- to the brink of nuclear war, had just passed, greatly increasing
- pressure for further development and testing of nuclear weapons.
- Therefore, in anticipation of possible publication difficulties, I
- decided to submit copies of the manuscript to a few noted scientists
- in the hope of gaining added support.
- One copy went to Dr. Russell Morgan, chairman of the Department of
- Radiology at Johns Hopkins University and head of the National
- Advisory Committee on Radiation of the U.S. Public Health Service.
- Dr. Morgan was one of the country's most knowledgeable experts in the
- areas of X-ray technology and low-dose radiation effects. In his
- reply, he stated that the article brought into focus important
- implications of the work of Stewart and MacMahon that had not been
- fully recognized, and recommended that it should be published with
- only a few minor changes. Dr. Morgan also gave me his permission to
- refer to his statement if the paper had to be resubmitted to {Science}
- after an initial rejection.
- Another copy went to Dr. Barry Commoner, professor of botany at the
- University of St. Louis and one of the founders of the Committee on
- Nuclear Information, a group that pioneered in the public
- dissemination of information on the effects of nuclear testing. Dr.
- Commoner said in his reply: "I believe that it [the article]
- represents a very important contribution to the subject. I hope that
- it will be published in {Science} just as it stands. . . . Your
- conclusion regarding the need for large-scale surveys of the incidence
- of leukemia and other forms of cancer is of great urgency."
- The article, however, was returned by {Science}, accompanied by
- copies of two reviews and a letter of rejection from the editor,
- Philip Abelson. Abelson was a physical chemist who had an extensive
- background in the nuclear field. For many years he had worked closely
- with Glenn Seaborg, later chairman of the AEC and president of the
- AAAS, on the development of processes for the production of uranium,
- and he was now a member of both the General Advisory Committee of the
- AEC and the Project Plowshare advisory committee. (Project Plowshare
- was the name given to the AEC's program for the development of
- peaceful uses for nuclear explosives.) In his letter, Abelson stated
- that he had reviewed the article himself and found that "there is not
- enough solid material to justify publication." He further expressed
- the opinion that "there is really no evidence of the functional
- relationship between the number of X-rays taken and cancer mortality."
- This meant that he did not consider significant the indications in the
- work of Stewart and MacMahon that the risk of cancer increased
- directly with the increase in X-ray dose, indications which were in
- sharp contradiction to the threshold theory.
- Upon examining the enclosed comments of the other two reviewers,
- who were nameless, as is the custom, I found that one was completely
- negative, stating that the article presented "no new observation" and
- ignored studies that showed no effects from diagnostic X-rays. The
- other reviewer, however, recommended publication. Apparently, then,
- it had been Abelson's opinion that weighted the scales in favor of
- rejection.
- A few days after the article was returned, I received an unexpected
- letter from Dr. James H. Lade, special assistant to the commissioner
- for radiological health of the New York State Health Department.
- Since 1951 Dr. Lade had also been director of the department's Bureau
- of Medical Defense, a part of the state's extensive Civil Defense
- Program, which had carried out an "exercise" at the time of the
- Albany-Troy incident. As medical director, Lade had been one of those
- who participated in the decision that no health protection measures
- were necessary after the incident and that no ill effects were to be
- expected. His letter read as follows:
-
- Dear Mr. Sternglass:
-
- I have had an opportunity to review your interesting paper on
- "Ionizing Radiation in the Pre-Natal Stage and the Development
- of Childhood Cancer," and noted your reference to Ralph Lapp's
- paper on the Troy-Albany fallout in 1953. We in this department
- have done a little investigation of the circumstances which
- obtained in the Troy-Albany area at that time and the number of
- cancer cases and deaths reported in the age group who were under
- two years of age at that time. You may be interested in the
- results of these investigations, summarized in my attached
- letter to {Science}.
- Yours very truly,
- James H. Lade, M.D.
- Director
-
- Lade, apparently, either had been the negative reviewer or had been
- consulted by him. The "Science" letter to which he referred had been
- published in the November 9 issue in reply to Lapp's article. In that
- letter Lade attempted to minimize the possibility of any radiation
- effects in the Albany-Troy area from the concentration of
- radioactivity in the milk by arguing that the cattle in the area had
- not been turned out to pasture until about May 12, 1953, or some two
- to three weeks after the fallout had arrived on April 25. He argued
- that in view of the seven-day half-life* of iodine 131, the radiation
- would have decreased to only one-fourth its initial intensity by the
- time the cattle were turned out, so that Lapp's estimates of the dose
- to infant thyroids were at least four times too high. Lapp had,
- apparently, been unaware of this factor when he made his dose
- estimates, but Lade failed to mention that even if Lapp's doses were
- reduced by a factor of four, they would still be vastly greater than
- the permissible limits set by government agencies. Lade's letter also
- did not take into account the dose from the longer-lived isotopes such
- as strontium 90, strontium 89, and barium 140, with half-lives of 28
- years, 50 days, and 13 days, respectively, which would certainly still
- be present two to three weeks after the fallout had arrived. Nor did
- he mention the information published by Professor Clark in the
- {Journal of the American Water Works Association}, namely, that in May
- and June, many weeks after the first rainout, fallout from additional
- tests repeatedly produced new levels of radioactivity comparable to
- those measured for April. This meant, of course, that Lapp's
- estimates, far from being four times too high, were actually much too
- low, for Lapp had based his estimates only on the April 26 fallout.
- Lade, as medical director of the Civil Defense group, worked
- intimately with the scientists from the New York office of the AEC who
- sponsored the measurements of radioactivity in the reservoirs of the
- area. Thus he presumably would have been aware of this circumstance.
-
- * The half-life of a radioactive isotope is the time it takes for the
- radioactivity to diminish to half its original intensity. The half-life
- of iodine 131 is 7 days so it is termed a short-lived isotope. Strontium
- 90, with a half-life of twenty-eight years, is a long-lived isotope. The
- radiation from a short-lived isotope is much stronger because all of it
- is given off in a shorter time.
-
- Lade further argued that because of the heaviness of the spring
- rains, the radioactivity had soon been largely washed off the
- vegetables and pasture. But Dr. Clark and his students had found that
- even extreme chemical treatment was only partially effective in
- removing the radioactivity from the leaves and other objects to which
- it clung. Thus, ironically, the only effect of the rains of May and
- June would have been to bring down even greater amounts of fallout
- than had come down in April.
- As a final point, Lade stated that a review of New York Health
- Department records indicated that no cases of thyroid cancer had since
- developed among the children who were under two years of age in 1953.
- His letter closed with the remark that "it seems most unlikely that an
- event which has resulted in no increase of thyroid carcinoma during
- the ensuing nine years will lead to such an effect in the future."
- Yet it was common knowledge among specialists in the field that
- radiation-caused thyroid cancer generally takes ten to twenty years to
- develop. And Lade said nothing about any increase in the incidence of
- leukemia, which by this time would certainly be detectable.
- It could thus be determined by someone with a scientific background
- that Lade's letter contained absolutely no evidence to support his
- conclusion that the Troy fallout had been harmless. But how could the
- general public ever guess? This was the voice of the New York State
- Health Department.
- Within a few weeks, I resubmitted my article to {Science} together
- with a letter referring to the statement given me by Dr. Russell
- Morgan. Within less than a month, it had been accepted for
- publication.
