- BY THE SPRING of 1963, when the article finally appeared in {Science},
- the levels of radioactivity in milk were reaching unprecedented
- heights all over the United States. Extreme concern was being voiced
- both by scientists and the general public regardless of the repeated
- reassurances by local public health officials and the AEC that no
- danger existed. The intensified pressure began to penetrate to the
- highest levels of government, and in June 1963 President John F.
- Kennedy announced that this country, the Soviet Union, and Great
- Britain had agreed to negotiate a treaty to end all atmospheric
- testing. He further stated that he had ordered an end to all such
- testing by the United States. In July the President delivered an
- address to the nation in which he urged the ratification of the treaty
- by the U.S. Senate. In this address, he referred to the threat of
- fallout as follows:
-
- . . . the number of children and grandchildren with cancer
- in their bones, with leukemia in their blood, or with poison in
- their lungs might seem statistically small to some, in
- comparison with natural health hazards, but this is not a
- natural health hazard--and it is not a statistical issue. The
- loss of even one human life, or the malformation of even one
- baby--who may be born long after we are gone--should be of
- concern to us all. Our children and grandchildren are not
- merely statistics toward which we can be indifferent.
-
- It appeared that the issues involved in the question of fallout
- hazards were at last receiving widespread public recognition. In
- Congress, hearings on low-level radiation effects were being held by
- the Joint Committee on Atomic Energy, and for the first time citizens'
- groups and private scientists with no government affiliations were
- invited to testify on this subject. In August I received a letter
- from John T. Conway, executive director of the Joint Committee,
- requesting my presence at the hearings. Leafing through the
- transcript of the first half of the hearings held in June, I found a
- reprint of my {Science} article. It was followed by a lengthy
- critique prepared by the AEC's Division of Biology and Medicine. On
- examination, the AEC critique proved to be strikingly similar in
- wording and theme to the negative review for {Science}. It denied
- that any effects from low-level radiation had been proven to exist,
- stating that I had ignored the studies which showed no effects. The
- AEC critique, however, went further and cited figures showing an
- actual reduction in childhood cancer rates after the heavy atmospheric
- testing in 1957. But the figures were only for children who were less
- than two years old when they died, a peculiar restriction, since
- Stewart and MacMahon had specifically demonstrated that cancer caused
- by the irradiation of unborn children only showed up *after* the age
- of two. No figures for older children were given by the AEC.
- The Joint Committee hearings opened on August 20, the same day that
- Dr. Edward Teller testified before the Senate against ratification of
- the Test-Ban Treaty. Dr. Teller, the renowned nuclear physicist who
- had been instrumental in the development of the hydrogen bomb,
- expressed in his testimony the main arguments advanced by the treaty's
- opponents. He raised the possibility of future military breakthroughs
- by the Russians, stating his conviction that in the 1961-62 test
- series they had acquired knowledge about missile defense that this
- country didn't have. "This is the main argument against the test-ban
- treaty," he said. "It weakens our defense, and as long as we have
- reason to distrust Soviet intentions, the weakness of our defense will
- invite attack. . . . I came to recognize many years ago that real
- cooperation between Russia and us in the near future is impossible."
- As to the possibility of danger from fallout, Teller flatly stated:
- "From the present levels of worldwide fallout there is no danger. The
- real danger is that you will frighten mothers from giving milk to
- their babies. By that, probably much more damage has been done than
- by anything else concerning this matter." Teller also stated that the
- treaty would endanger the program for the peaceful uses of nuclear
- explosions in the Project Plowshare program. He expressed his belief
- that such explosions could be carried out in "a very clean way," so
- that fifteen minutes afterward people could walk in the resulting
- crater "without exposing ourselves to more radiation that we have
- taken year in and year out in our laboratories."
- At the same time as Dr. Teller was making this statement, in
- another part of the capital Dr. C. W. Mays of the University of Utah
- was testifying at the Joint Committee hearings about the thyroid doses
- received by children in Utah from one of the AEC's Project Plowshare
- explosions the year before. As measured by University of Utah
- scientists, the doses ranged from 10 to 60 rads--anywhere from ten to
- a hundred times the government's maximum permissible yearly limit for
- that body organ.
- The second day of the Joint Committee hearings, during which I was
- present, began with the testimony of Dr. Shields Warren, who
- represented the National Academy of Science's Advisory Committee on
- the Biological Effects of Radiation. Dr. Warren had been the first
- director of the AEC's Division of Biology and Medicine, and as such he
- had been responsible for all of the AEC's early research and planning
- relating to the health effects of fallout. He was also head of the
- U.S. delegation to the United Nations Scientific Committee on the
- Effects of Radiation. Dr. Warren began his testimony with a review of
- the effects of radiation on man, animals, and plants. The lowest dose
- listed on his chart was 0.001 rad, or 1 millirad, and this was
- followed by 0.01 rad, which he indicated as giving "no detectable
- effect." The next highest dose was 1.0 rad, again with the legend "no
- detectable effect." Dr. Warren evidently did not accept the evidence
- of Stewart and MacMahon, which indicated that 1.0 rad received during
- pregnancy produced something like a 50 percent increase in the rate of
- childhood leukemia and cancer, clearly a "detectable" effect.
- Nothing very serious appeared on Dr. Warren's chart until he got to
- 1000 rads. At 10 rads the legend was: "Barely detectable qualitative
- changes in lymphocytes," while at 100 rads the chart indicated only
- "mild acute radiation sickness; slight diminution in blood cell
- counts. Possible nausea and vomiting. . . ." Yet the studies of
- Hiroshima had revealed a doubling or tripling of leukemia deaths among
- the surviving adults exposed to this dose.
- Only at 1000 rads did radiation actually appear lethal:
- "Depression of blood cells and platelets . . . death within twenty
- days." This was profoundly misleading: It was common scientific
- knowledge that 50 percent of all individuals exposed to 400 rads to
- the whole body would die within a matter of weeks or months, while for
- 700 rads the figure was 95 percent.
- For 10,000 rads, Dr. Warren's chart listed "Immediate
- disorientation and coma. Death within hours . . ." while "death of
- all living organisms" was reassuringly indicated as not occurring
- until 10,000,000 rads. In conclusion, Dr. Warren quoted the following
- passage from the United Nations 1962 report on fallout hazards, which
- he had helped to prepare:
-
- It must be recognized that the human species has, in fact,
- always been exposed to small amounts of radiation from a variety
- of natural sources and that the present additional average
- exposure of mankind from all artificial sources is still smaller
- than that from natural sources.
-
- This, then, had been the voice of the AEC's Division of Biology and
- Medicine, the National Academy of Sciences, and the U.S. delegation to
- the United Nations Scientific Commission.
- When Congressman Melvin Price asked Dr. Warren what effects he
- would expect to observe in the 250,000 children in Utah who might have
- received 4.4 rads to their thyroids, as Dr. Mays had testified the day
- before, he replied: "I think it would be hard to find any effect, Mr.
- Chairman." But as Dr. Mays had suggested, if one does not look, one
- is not likely to find such effects, and indeed, no one had conducted
- the necessary studies of the children in Utah, in Albany-Troy, or, for
- that matter, anywhere else in the world.
- The next witness was Dr. E. B. Lewis of the California Institute of
- Technology, whose "single-hit," linear theory of cancer causation
- supplied an explanation for the findings of Stewart and MacMahon.
- This theory had formed the basis of my argument that the cancer-
- causing effects of radiation were cumulative and that doses received
- gradually from fallout would be similar in effect to those received
- all at once from diagnostic X-rays. Dr. Lewis's latest evidence,
- based on a study of leukemia incidence among radiologists, indicated
- that low doses of radiation delivered over a period of many years
- could indeed lead to an increased incidence of leukemia, a finding
- that further buttressed his original theory.
- There was now only one more witness scheduled to be heard before
- Dr. Brian MacMahon. This was Dr. Hyman Friedell, professor of
- radiology at Western Reserve University. The main burden of his
- testimony, as he stated, was to urge radiation protection agencies to
- set their standards on the basis of the linear theory of radiation
- damage, according to which there was no safe threshold of exposure.
- Now Dr. MacMahon took the stand. He opened his testimony with an
- explanation of why certain other studies had not appeared to confirm
- Dr. Stewart's and his own results: "Every one of the negative studies
- has been based on small numbers, and in no instance do the results
- differ in a statistically significant degree from the expectation of a
- 40 percent increase in cancer risk among exposed children." Thus, in
- defense of his own work, Dr. MacMahon had effectively answered one of
- the major points in the AEC's critique of my article. He went on to
- summarize his results as follows:
-
- I suggest therefore that the existing evidence is overwhelmingly
- indicative of an increase in cancer risk for children
- diagnostically exposed in utero; that this increase is seen for
- leukemia as well as for a variety of other individual forms of
- cancer; that the best estimate of this increase is that it is
- about 40 percent in excess of "normal" cancer mortality in the
- United States.
-
- Turning next to the implications of his findings, he stated:
-
- It seems to me that if this association is accepted, we must
- consider very seriously the possibility of cancer production by
- low doses of radiation such as encountered in X-ray diagnosis
- and even fallout.
-
- As to the existence of a possible "threshold," Dr. MacMahon went on
- to say:
-
- The exposure dose associated with pelvimetry [pelvic X-rays] at
- the time of these studies is not known, but it was probably of
- the order of 2 to 3 rad [for a series of X-rays]--substantially
- below the 50 rad that has frequently been mentioned as a
- possible threshold level. If a threshold for leukemia induction
- exists, then it must be below 2 rads. It would be a coincidence
- indeed if a threshold existed just below the dosage level at
- which studies have been undertaken.
-
- One other major issue remained to be discussed, and that was the
- evidence for an increase in cancer risk with an increase in dose--
- termed the "dose-response" relationship. To this point, MacMahon now
- addressed himself as follows:
-
- Furthermore, there is some indication in both Stewart's and our
- own data that a dose-response relationship exists even within
- the low-dose range that is being considered.
-
- Thus, MacMahon, together with all the other nongovernment
- scientists who testified in this part of the hearings, presented
- evidence in conflict with the AEC's claims for the existence of a safe
- threshold.
- Inevitably, Dr. MacMahon was asked his opinion of the use to which
- I put his data in my {Science} paper. He summarized his reply as
- follows: ". . . the argument used by Dr. Sternglass does not convince
- me personally, but, on the other hand, I cannot deny that ultimately
- his point of view may be correct." He further stated, however, that
- he agreed with all the comments in the AEC critique. This seemed
- puzzling, since I felt he had just answered the most serious points in
- his own testimony. It became clear that I would have to amass much
- stronger evidence before my hypothesis could gain the public support
- of many scientists.
- After a brief recess, Dr. Eric Reiss was called to the witness
- stand. Dr. Reiss was a St. Louis physician and a co-founder, with Dr.
- Barry Commoner, of the St. Louis Committee for Nuclear Information.
- In his presentation on behalf of the St. Louis group, he concentrated
- on the subject of local fallout incidents resulting from the AEC's
- tests in Nevada. Referring to the many reports on local fallout
- prepared by the AEC, he pointed out that the general conclusion in all
- these official reports had been that "the test program has been
- carried out without any discernible threat to the safety of the local
- population."
- "In contrast," Dr. Reiss went on to say, "our analysis of the same
- monitoring data published by the AEC shows that as a result of nuclear
- tests at the Nevada Test Site, in the period 1951-62, a number of
- local populations, especially in Nevada, Utah, and Idaho and probably
- other communities scattered throughout the continental United States,
- have been exposed to fallout so intense as to represent a medically
- unacceptable hazard to children who may drink fresh locally produced
- milk." He explained that the discrepancy between the AEC's
- conclusions and those of the St. Louis group arose out of the fact
- that the AEC only measured the external dose from the fallout in the
- environment, while his group also measured the internal dose from the
- fallout particles concentrated inside the body, as Dr. Lapp had done
- in the case of Troy.
- Dr. Reiss proceeded to present figures indicating that for 10 rads
- to the thyroid approximately one in 2860 children might be expected to
- develop thyroid cancer. Because of the long latent period for this
- disease, he explained, the damage would not show up for many years.
- Possibly ten to twenty. He then cited estimated thyroid doses of 3 to
- 18 rads for the large population of Salt Lake City, Utah, as a result
- of fallout on May 7, 1952, and 5 to 40 rads for Albany-Troy on April
- 26, 1953 (this did not even include the much heavier fallout in June).
- Such hazardous doses, Dr. Reiss pointed out, arose not only from
- atmospheric tests but also from certain underground tests: "Venting
- [leaking of radioactivity] has been reported for at least seven
- underground nuclear tests," said Dr. Reiss, adding that his group was
- able to calculate, for example, that "fallout from the underground
- `Gnome' shot delivered sufficient fallout to the vicinity of Carlsbad,
- New Mexico, to cause thyroid dose levels of from 7 to 55 rads to
- children."
- And then Dr. Reiss turned to an astonishing aspect of the whole
- problem: If the dangerous internal doses had been estimated at the
- time, "simple preventive measures could have been taken to avoid
- exposure." It would only have been necessary to warn the inhabitants
- of the area to avoid drinking fresh milk produced locally until the
- iodine levels died down. "We know of no instance," said Dr. Reiss, "
- in which such a warning was issued until the summer of 1962, when high
- iodine 131 levels observed in commercial milk supplied in Utah led
- state health officials to divert current milk from the market." And
- finally, Dr. Reiss noted that correct estimates of internal doses
- should have been possible by as early as 1954 *on the basis of the
- then-available scientific theory*.
- The questioning of Dr. Reiss was nearing its end when John Conway
- asked him why his group had made only theoretical calculations of the
- thyroid doses without benefit of any direct measurements of the iodine
- levels in the milk. "I am delighted you brought that up," Reiss
- answered, "because it is the nub of the problem. If measurements were
- available, we would obviously have used them. The question is, why
- were no measurements made or reported publicly by those who had been
- charged with the protection of our health and safety?"
- That evening the {Washington Post} gave prominent coverage to
- Reiss's testimony, as well as to the testimony given at the Senate's
- test-ban ratification hearings. At those hearings, Dr. John S.
- Foster, Jr., the new director of the AEC's Livermore Laboratory, where
- the hydrogen bomb had been developed, had offered his opinion on
- fallout hazards:
-
- You are asking for a quantitative answer which involves the
- understanding of an effect, namely the effect on the human being
- that is so small compared with his [radiation exposure from]
- background that we have not been able to measure it. One way to
- look at it would be to say that the fallout from all past tests
- affecting man for the next 50 to 100 years would be something
- like the same thing as deciding to live a few hundred feet
- higher up, higher above sea level; that is what it means.
-
- Senator Robert Byrd of West Virginia then asked Dr. Foster what
- importance should be attached to the public's fears of fallout. Byrd
- phrased his question as follows: "If I may pose a hypothetical
- question, are you saying, in essence, that if you were a senator with
- the knowledge that you possess in the scientific field . . . you would
- disregard entirely this factor [public opinion] in your reaching a
- decision?"
- To which Foster replied: "That is correct, sir, although it would
- be a very difficult position for me to put myself into. . . ."
- The third day of the Joint Committee's low-level radiation hearings
- opened with my testimony. I reviewed all the evidence regarding low-
- level radiation effects on unborn children, presented my arguments as
- to the probable similarity in effects of X-rays and fallout radiation,
- and gave estimates of the increase in childhood cancer that might be
- expected from nuclear testing. Then the questioning period began.
- Congressman Craig Hosmer asked me how there could be any evidence
- in Stewart's and MacMahon's studies for a dose-response relationship
- when the radiation dose from hospital X-ray machines was known to
- differ widely from hospital to hospital, due to variations in the
- adjustment and quality of the machines. Such differences would mean
- that some mothers might have received the same or greater dose from a
- single X-ray as others received from two or even three. Therefore,
- the finding of Stewart and MacMahon that there was an increase in
- cancer risk with the number of X-rays taken might not indicate a
- dose-response relationship. I explained that it was also true,
- however, that in the case of any one machine, the mothers who received
- two X-rays from it would definitely have received twice as much
- radiation as those who were X-rayed only once. Since the ratio of
- single pictures to double or treble pictures taken was generally the
- same for each X-ray machine, there could be no question that, on the
- average, the mothers who received two X-rays had received twice as
- much radiation as those who received only one.
- Congressman Hosmer next asked why one couldn't test the validity of
- the dose-response relationship simply by examining the statistics for
- leukemia in children after the test series in the early 1950s. I
- pointed out that this was precisely what Lapp, Mays, Reiss, myself,
- and others had urged the government to do without success.
- The next question involved the principal argument used by the AEC
- to minimize the possible effects of fallout. Congressman Holifield
- asked whether I was aware that testimony had been presented by
- government scientists that fallout from all past testing had raised
- background radiation by only some 10 percent. Since the typical
- background dose was 100 millirads per year, this seemed to be only 10
- millirads additional radiation, much less than the 200 millirads
- received from a modern pelvic X-ray, or than the dose of 200 to 400
- millirads that I had calculated for the recent test series.
- What the spokesmen for the AEC and the Federal Radiation Council
- had done was to take the total radiation dose from all the bombs
- detonated so far--some 700 millirads--and average it out as if it were
- received uniformly over a seventy-year life span at a rate of 10
- millirads per year. But in fact, most of the dose comes from the
- short-lived isotopes that predominate in fallout, and is thus
- delivered in the first few months after the tests. To illustrate
- this, I cited figures published just a few months before by the AEC's
- Brookhaven National Laboratory, located on Long Island, not far from
- New York City. According to these figures, during the first six
- months of 1963, the average radiation exposure on Long Island had
- risen to 4.7 millirads per week, as compared with a normal background
- rate of only 1.7 millirads per week. This meant that in only half a
- year the dose received by individuals in this area would be about 122
- millirads as compared with a normal dose of only 44 millirads. Thus,
- instead of the negligibly small 10 percent increase which the AEC's
- seventy-year averaging procedure would give, the actual exposure to an
- infant in the womb would have been nearly triple the background rate.
- And this dose did not even include the effects of internal
- concentration. This, then, was the reasoning behind the reassuring
- statements of the world's radiation protection agencies that doses
- from atmospheric testing were negligible compared with all the sources
- of radiation in man's natural environment.
- Congressman Hosmer next raised the point that the greater
- background radiation due to cosmic rays in an area of high altitude
- such as Denver as opposed to that in an area at sea level such as Long
- Island should lead to a higher leukemia rate in Denver. But in point
- of fact, as I stated, the difference in total background radiation
- between these two areas is actually quite small because most
- background radiation comes from sources other than cosmic rays.
- Cosmic rays contribute only about 30 millirads at sea level, compared
- to 50 millirads from the rocks and soil and 20 millirads from traces
- of natural radioactive substances in our body. Going to an altitude
- of 5000 feet increases the cosmic ray dose by only 40 percent, or a
- total of 12 millirads. Since place-to-place differences of 20 or 30
- millirads in the radioactivity of rocks are common, the small
- difference due to altitude is easily masked by this factor alone.
- Furthermore, cosmic rays do not concentrate in critical body organs as
- does fallout.
- Thus, it would be nearly impossible to find differences in leukemia
- rates as a result of altitude differences even as large as those for
- Denver and Long Island, considering that MacMahon had to use a study
- group of some 70,000 exposed children to clearly establish an effect
- from about 1000 millirads of X-rays. And I added that there are of
- course other factors beside radiation that enter into the likelihood
- of a child developing leukemia, making such a comparative study of the
- effects of slightly different background levels next to impossible.
- Following up this point, Congressman Hosmer suggested that if
- factors other than radiation were involved in the cause of leukemia,
- did this not invalidate MacMahon's study? To this I replied that, in
- such a study, comparisons are carried out with control groups for whom
- all the other factors are, on the average, nearly the same as for
- those exposed to X-rays, thus essentially eliminating the effect of
- such factors on the outcome.
- After some discussion of the size of the dose from fallout, the
- chairman indicated that the committee's counsel, John Conway, had some
- points he wished to raise. After a lengthy prelude, Conway led up to
- the fact that the Federation of American Scientists' news release
- based on my paper said that 100 megatons of nuclear fission energy had
- been released in the 1962 test series. Conway argued that since the
- amount released in 1962 was actually 76 million tons, then my estimate
- of the expected number of leukemia deaths was too high.
- But it was clear from both my original paper in {Science} and my
- written testimony that the figure of 100 megatons applied to the
- entire test series that began in September of 1961 and ended late in
- 1962, not just to the amount detonated in 1962 alone. Thus, the news
- release, which was not even prepared by me, should have said more
- precisely, "1961-62 test series."
- When this became clear, Chairman Price intervened to point out the
- simple nature of the misunderstanding, and when Conway nevertheless
- wanted to pursue the matter further Price thanked me for my testimony
- and called the next witness.
- The debate over the test-ban treaty continued in Congress through
- most of September, and then the U.S. Senate voted overwhelmingly for
- ratification.
- A highly revealing postscript to the entire test-ban treaty debate
- came to light in December, when the full proceedings of the Joint
- Committee hearings were published. Inserted in the record was a
- letter from Dr. Harold Knapp, a fallout specialist who had recently
- resigned from the AEC's Division of Biology and Medicine. In his
- letter, Dr. Knapp made reference to a 1957 incident in which a nuclear
- reactor in Windscale, England, had gone out of control and emitted
- tremendous quantities of radioactivity into the atmosphere. The
- contamination from iodine 131 was so great that the crops and milk for
- hundreds of square miles around had to be seized and dumped.
- According to Dr. Knapp's letter, in 1960, when he was doing fallout
- research for the AEC, he came to the startling conclusion that in Utah
- "depositions of iodine 131 per unit area *at many inhabited ranches
- and communities must on several occasions have exceeded the maximum
- iodine 131 concentrations on pasturage found after the Windscale
- accident*." (Emphasis added.)
- As an example, Knapp cited an incident of relatively heavy fallout
- in the St. George, Utah, area on May 19, 1953. His calculations
- indicated that 24 hours after the explosion the iodine levels in milk
- must have reached 700,000 to 2,600,000 micromicrocuries per liter. He
- estimated that the thyroid dose for an infant who drank one liter
- (slightly more than a quart) of this milk each day for the three weeks
- following the test would be anywhere from 120 to 440 rads.
- Knapp wrote a report containing these conclusions in 1960, but the
- AEC did not release his report for publication until August 16, 1963,
- just a few days before the second half of the Joint Committee hearings
- began, by which time it was evident that the independent scientists
- from Utah and St. Louis were going to make public their own similar
- findings. Thus, during the entire early effort to achieve a test-ban
- treaty, this shocking and vital information was kept from the people
- and political leaders of the world, while hundreds of megatons of
- bombs were exploded by the U.S. and Russia during 1961-62. And since
- Knapp's report had not even been made public by the AEC and the Joint
- Committee by the time of the first half of the low-level radiation
- hearings in June of 1963, it had still been possible for the AEC to
- mislead Congress and the public until just before the end. From page
- 225 of the proceedings of the June hearings:
-
- REPRESENTATIVE HOLIFIELD: And the testimony before this
- committee has been that tolerable permission dose has not
- been reached by the amount of radiation that comes from
- manmade fallout radiation, is that not true?
- DR HARLEY: Yes, Sir.
-
- Dr. Harley was John Harley, the former colleague whom Professor
- Clark had telephoned at the time of the Albany-Troy incident. At that
- time a scientist with the AEC's Health and Safety Laboratory in New
- York City, Harley had since become head of the lab, which had been
- responsible for the classified reports on the Troy fallout during the
- spring of 1953.

- The Evidence Begins to Emerge
-
-
-
-
- IT WAS NOW an established fact that potentially dangerous radiation
- doses had been received by large numbers of people from fallout. What
- remained to be established was whether or not these doses had actually
- caused any damage. No direct statistical evidence had yet been
- gathered by either the AEC or federal and state health agencies, or,
- if it had been gathered, it had not been published.
- This situation was abruptly transformed in March of 1964, when
- another letter by J. H. Lade of the New York State Health Department
- appeared in {Science}. This letter was written in response to
- repeated prodding by Ralph Lapp, who kept challenging the department
- to make public the actual figures after Lade had claimed in the
- September 1963 issue of {Science} that no increase in childhood
- leukemia had occurred as a result of the 1953 rainout. The exact
- words used by Lade in making this claim had been:
-
- The cancer report files of this department reveal no increase in
- the incidence of cancer or leukemia over the past ten years in
- children of the Albany, Troy, and Schenectady areas--who were 15
- years or younger in 1963--as compared with children of this age
- elsewhere in upstate New York.
-
- Lade's new letter contained the first detailed information on leukemia
- deaths among the children of the area. This was the data on which he
- had based the above conclusion.
- The data consisted of a table that included all reported fatal
- leukemia cases among children under fifteen years of age in the
- Albany-Troy-Schenectady area between 1952 and 1962, together with the
- years in which these children were born. Examination of the table
- showed that, beginning in the fourth to fifth years after the 1953
- rainout, the yearly number of reported leukemia cases quadrupled.
- This was strikingly similar to the delay in onset observed in the
- studies of Stewart and MacMahon and among the survivors of Hiroshima
- and Nagasaki. In the Troy area, after the eighth year, the number of
- cases began to decline once more, as they also did in the two Japanese
- cities. During the years 1952-55, before any radiation-caused
- leukemia cases would be expected to appear, there were a total of nine
- cases among children under age ten for whom the data was complete.
- During the years of expected peak incidence, 1959-62, there were a
- total of thirty cases. Statistical estimates demonstrated that the
- chances were less than one in a billion that this increase of twenty-
- one cases could be regarded as purely accidental.
- And when the cases were examined according to the year of birth,
- there was a very noticeable sudden increase in leukemia among the
- children born in 1953 and 1954, the period when the fallout radiation
- would have been strongest. When grouped in two-year periods, the
- figures in Lade's table for children under ten showed the following:
-
- Birth Years No. of Cases
- ----------- ------------
- 1943-44 4
- 1945 46 5
- 1947-48 8
- 1949-50 5
- 1951-52 6
- 1953-54 13
-
- How, then, had it been possible for Lade to claim that there had
- been "no increase in the incidence of cancer or leukemia over the past
- ten years in the children of the Albany, Troy, and Schenectady areas"?
- Upon rereading his exact statement, it became apparent that he had
- used a modifying phrase whose significance would easily escape the
- casual reader. This phrase was: "as compared with children of this
- age elsewhere in upstate New York."
- But the "classified" measurements made by the AEC's New York lab
- had shown that the *entire upstate New York area* received heavy
- fallout on April 26, 1953, and again during the next few months.
- Under these circumstances, there would of course be little or no
- *difference* in leukemia rates between Albany-Troy-Schenectady and
- elsewhere in upstate New York. Although he presented no data, Lade's
- statement clearly implied that in fact there had been similar
- increases in *all* these areas. (And indeed, later investigations
- revealed that there had been such rises all over New York State
- following three to five years after the onset of Nevada testing.)
- In his 1964 letter, Lade presented a final argument to "rule out
- the fallout as a major factor in the leukemia incidence in that area
- for the 1953 births." According to his figures, there were also a
- large number of leukemia cases among the children born in 1956. Thus,
- Lade argued that the sharp rise in leukemia among those born in 1953
- could not have resulted from the fallout, since there was also an
- increased incidence among the children born in 1956, when there
- presumably was no major fallout incident.
- This piece of evidence seemed puzzling, especially since all the
- other data pointed so strongly to fallout. But then, a few months
- later, new light was thrown on the situation when the news of an
- extremely important study appeared in {The New York Times}. A group
- of investigators working with Dr. Saxon Graham at the Roswell Park
- Memorial Cancer Research Institute in Buffalo, New York, and at two
- other cancer research institutions, had found that the children of
- parents who had been X-rayed as many as five to fifteen years *before*
- the mothers became pregnant also had a significantly increased
- likelihood of developing leukemia. This finding suggested that
- radiation could cause a type of *genetic* damage to the sperm cells of
- men and the ovaries of women that would make their children more prone
- to developing this disease.
- In the case of Troy, then, it was indeed possible that such a
- genetic effect of radiation could lead to a greater incidence of
- leukemia among the children born in the years following.
- There was another very important finding of the Roswell study:
- Children who had received multiple exposures from a series of
- diagnostic X-rays to different parts of their bodies had a distinctly
- greater risk of leukemia than those who had only one part X-rayed.
- Fallout, due to the concentration of isotopes in various parts of the
- body, would lead to exactly this type of multiple exposure. Thus, in
- the Troy area, even children who were born *before* the rainout would
- be expected to show an increased risk of leukemia.
- Independent studies had now demonstrated that radiation could cause
- leukemia in children prior to conception, in the womb, and after
- birth. What would the Troy data show if the cases were examined
- according to which of these three stages of development the children
- were in when the fallout arrived? When this was done, a fact of
- utmost significance emerged: Those children who had been in the womb
- or who were already born at the time of the fallout were, on the
- average, one or two years older at death than the children who had
- been conceived afterward. This was exactly the same characteristic
- shift toward older age at death that had been observed by both Stewart
- and MacMahon in their studies of children X-rayed while in the womb,
- and it had also been observed in studies of leukemia among infants who
- had received medical X-ray treatment. It was as if the children of
- Troy had been marked with a sign. The fact that the children
- conceived after the fallout showed the normal earlier age at death was
- perfectly consistent, for it is generally acknowledged that there is a
- large genetic factor in all normally developing leukemia cases and
- that a significant portion of these cases are caused by genetic damage
- from natural background radiation. Thus the children whose leukemia
- had been caused by radiation damage to their parents' genes would be
- expected to show the normal age at death.
- None of the data supplied by Lade was therefore inconsistent with
- the hypothesis that the fallout had caused the increase in leukemia in
- the Albany-Troy-Schenectady area. And this might well be true for
- other types of childhood cancer. Further investigation was definitely
- indicated. Since I anticipated difficulty in obtaining more complete
- and up-to-date data from Lade, I again contacted Dr. Russell Morgan,
- chairman of the U.S. Public Health Service's National Advisory
- Committee on Radiation. After reviewing Lade's data and my
- conclusions, Dr. Morgan suggested that I use his name in writing to
- the New York State Commissioner of Health, Dr. Hollis Ingraham. In
- July I wrote Dr. Ingraham, asking for further information relating to
- cancer incidence in the Troy area and mentioning Dr. Morgan's concern
- about the data published by Lade. A few weeks later I received a
- letter from Lade indicating that he felt sufficient data was already
- available in his 1964 {Science} letter. It appeared that the New York
- State Health Department did not want to see the matter pursued any
- further.
