Atomic energy technology, politics, and perceptions from a nuclear energy insider who served as a US nuclear submarine engineer officer

Health Effects

One vignette in radiation fear campaign

June 5, 2020 By Rod Adams 13 Comments

Abject fear of radiation, even at low doses, is a root cause of the cost and schedule difficulties associated with atomic energy development and deployment.

At Atomic Insights, we believe that most of the fear of low dose radiation is not only unwarranted, but it is also purposely created, taught and carefully reinforced by people.

Every person that participates in the campaign has their own unique combination of motives and techniques, but some of the major factors are a desire to prevent use of nuclear weapons, a desire to eliminate nuclear weapons completely, a desire to discourage nuclear energy development for competitive reasons, and a desire to discourage use of moderate doses of radiation as a treatment or a cure for various health conditions.

The radiation fear campaign has been going on in earnest since June 13, 1969. That was the date when the New York Times ran a front page headline stating that “SCIENTISTS TERM RADIATION A PERIL TO THE FUTURE OF MAN.”

Throughout the decades since that first proclamation was issued, there have been additional claims and stories with fear creation and maintenance as either a sole or ancillary purpose.

Here’s a sample from the campaign.

On October 12, 1969, the New York Times published an article written by Kathleen Teltsch under the following headline: “RADIATION LINKED TO RETARDATION: U.N. Report Warns of Even Low Doses in Pregnancy.”

That is a headline that can capture attention and a subtitle that stokes fear, especially among young women who are planning to have children. It will cause fear, anxiety and guilt among young mothers that have, for one reason or another, been exposed to radiation while pregnant with children that are still growing.

It is an unfortunately truth about newspaper readers that some finite portion of the audience only reads or remembers headlines and subtitles.

But there is more to the story.

Though this article did not make it to the influential front page, the editors carefully chose a placement that was almost as impactful.

Page 52 of the Sunday, Oct 12, 1969 edition of the New York Times

It was a full, single column article running from top to bottom of the left-most column on a page that was otherwise filled with an attractive ad for the Gimble’s 127th Annual Columbus Day Sale. October 12, 1969 was a Sunday, so the sale was happening the next day.

It seems likely that the article and its placement would draw people in the exact demographic that might be most interested in – and frightened by – finding out that radiation harms children in the womb.

I’m not a newspaper skimmer lazily flipping through sale ads on a Sunday morning of a three day weekend in the late 1960s, so I carefully read the rest of the article. I wanted to learn more about what the New York Times and the United Nations wanted to tell people about radiation health effects in the fall of 1969.

The scientists that wrote the report issued in October 1969 were members of the standing committee that the United Nations had created in 1955 to study effects of atomic radiation. The primary source for their reports was data gathered by the Atomic Bomb Casualty Commission, which studied effects of the bombs dropped on Hiroshima and Nagasaki.

Though the article subtitle gives the impression that even low doses were found to be harmful, the article states that the specialists who wrote the report found that evidence of harm at low doses was “extremely tenuous” but harm could not be “excluded.”

By their definition, any dose less than 50 roentgens was considered to be low. The article reminds readers that a typical diagnostic X-ray would give a dose of 1 R or less, but also tells them that doses have been gradually lowered through technological improvements. Some readers who might have had X-rays while pregnant in the past are left wondering if they might have received higher doses.

The article did not mention that 50 R was 10 times the maximum allowed annual dose for trained radiation workers at a nuclear power plant. It substantially exceeded the amount of radiation that any member of the public might expect to receive, even if accumulated over a lifetime living at the fence line of a power plant.

The report was based on studying development of 1,613 children whose mothers were pregnant at the time of the atomic bombings.

Researchers binned the victims based on the calculated doses the mothers received from the explosion and its aftermath. It’s worth noting that virtually all of the radiation received was instantaneous. Those who received higher doses were highly likely to have been subjected to additional bomb effects including blast and heat.

Though there was a strong correlation between mental retardation and radiation doses above 200 R, the correlation was much lower at doses between 50 and 99 R. Below 50 R, the incidence of retardation was less than 1%.

There is no evidence presented indicating that the incidence of retardation among children exposed to less than 50 R is any different from the level that might be found any any randomly selected population.

Though the article provides accurate information that should be reassuring to anyone with critical reading skills, it was headlined, placed and structured in a way that creates fear and uncertainty.

In the emotionally charged topic of child development and the responsibility of mothers to provide protection, it provides reason to fear radiation – even at low doses – when there is no evidence indicating that fear is the correct response.

Of course, the editors at the New York Times didn’t create the report, and Ms. Teltsch probably didn’t write the headline, but both helped make this an effective component of the long-running campaign.

The article concludes with some hints about why the report was issued and why the Times chose to cover it in a way that would capture attention and perhaps stimulate action.

Even though the US, the UK and the Soviet Union had agreed to stop testing nuclear weapons in the open atmosphere by 1963, both France and Communist China were still engaged in atmospheric testing programs that still released uncontrolled fallout.

Underground testing was still seen to be somewhat risky because test sites still leaked.

Not stated in this article – but known to contemporary readers – is the fact that there were dozens of nuclear power plants under construction in the United States.

Though begun during a period of optimism about atomic energy and its potential for benefiting electricity customers, there was a growing level of concern about health effects of radiation from routine operation of those plants. People concerned about those effects were making their concerns known through active efforts to slow nuclear plant construction and add increasing layers of protection.

History students can also find numerous indications that the coal, oil, gas, freight and banking industries had always been worried about losing sales to nuclear power.

It’s not difficult to understand that they would be happy to buy ads in newspapers that published stories that might slow their atomic competitor.

How did leaders of the Hydrocarbon Establishment build the foundation for radiation fears?

May 21, 2020 By Rod Adams 13 Comments

On December 8, 1953 President Eisenhower announced to the UN that the US knew how to harness atomic energy to produce useful power. He stated that the US was willing to widely share that knowledge. He described an especially intriguing possibility of using atomic energy to bring power to the “power-starved areas of the world.”

The more important responsibility of this atomic energy agency would be to devise methods whereby this fissionable material would be allocated to serve the peaceful pursuits of mankind. Experts would be mobilized to apply atomic energy to the needs of agriculture, medicine and other peaceful activities. A special purpose would be to provide abundant electrical energy in the power-starved areas of the world.

From President Eisenhower’s speech to the United Nations on December 8, 1953

While that was an inspiring thought for most listeners, there’s no doubt that the world’s fuel supply industry recognized a dire threat to their dominance.

Within months after the Atoms for Peace speech, influential people worried about competition from atomic energy began mobilizing an effort to shape the way the world would receive President Eisenhower’s offer.

World’s largest and most influential science funder takes aim at the atom

During a 1954 Rockefeller Foundation Board of Trustees meeting, several of the trustees asked the President of the National Academy of Sciences (NAS) if his esteemed organization would be willing to review what was known about the biological effects of atomic radiation.

The board did not have to pick up the phone or send a letter to make that request. Detlev Bronk, who was the serving president of the NAS, was already at the table as a full member of the Rockefeller Foundation Board of Trustees. The board agreed that, based on their interpretations of recent media coverage, the public was confused and not properly informed about the risks of radiation exposure and the potential benefits of the Atomic Age.

The tasking given to the NAS was to form a credible committee that would study the science and issue a report “in a form accessible to seriously concerned citizens.”1

At the time the request to the NAS was made, the Rockefeller Foundation had been funding radiation biology-related research for at least 30 years, including the Drosophila mutation experiments that Hermann Muller conducted during the 1920s at the University of Texas. Foundation board members and supported scientists had been following developments in atomic science since the earliest discoveries of radiation and the dense energy stored inside atomic nuclei.

The prevalent understanding of radiation effects in 1954 was that it was known to be dangerous at high rates of exposure, but that lower rates had no immediate or measurable long term effects.

Just a few years before the Rockefeller Foundation board decided to revise the world’s understanding of radiation health effects, the Tripartite Conferences on radiation protection had revised the permissible limits to 0.5 mGy/day or 3 mGy/week. Though some had raised concerns, there was no evidence of any harm to people who had been exposed at levels slightly above the new permissible doses.

The new level was a 50% reduction from the previous limits, but it was based on adding a safety factor, not on avoiding levels with known harm.

In between these two extremes there is a level of exposure, — in the neighborhood of 0.1 r/day — which all experience to date show to be safe, but the time of observation of large numbers of people exposed at this rate under controlled conditions, is too short to permit a categorical assertion to this effect.2

Biological Effects of Atomic Radiation

The first NAS Biological Effects of Atomic Radiation committee began its work in April 1955. There were six subcommittees, each of which spent about a year researching and writing their section of the committee’s report.

Unlike the 1948 Tripartite Commission documents establishing permissible dose limits, the NAS BEAR 1 committee report, especially the section from the Genetics Committee, benefitted from skillful promotion. It received extensive media coverage and public attention. Arthur Sulzberger, the publisher of the New York Times, served on the Rockefeller Foundation Board of Trustees and freely provided his media expertise.

The NAS held a press conference announcing the release of the report and answering questions in Washington, DC on June 12. Among other media attention, that press conference resulted in no less than six related articles in the June 13, 1956 edition of the New York Times. Several additional articles were published during the following weeks. The selection of pieces included a lengthy article that started at the top of the right hand column of the paper and continued with another 20-25 column inches on page 17.

NYT Above fold June 13 1956

The June 13 edition also included a full text copy of the text of the Genetics Committee report that was specifically written for public consumption. That article filled nearly three pages of the paper, with the opportunity for three separate full span headlines.

Genetics Committee headlines 1
Genetics Committee headlines 2
Genetics Committee headlines 3

The report from the Genetics Committee of the National Academy of Sciences’s first biological effects of radiation committee was pure gold from the point of view of those who wanted to scare people and temper the growing optimism about the virtually unlimited power promised by Atomic Age visionaries like President Eisenhower. Here are the first two paragraphs from the front page article.

A committee of outstanding scientists reported today that atomic radiation, no matter how small the dose, harms not only the person receiving it but also all his descendents (sic).

The report was part of a survey produced by six committees of the National Academy of Sciences, a private nonprofit organization. It was the most comprehensive United States effort to determine how the future of the human race might be affected by the unleashing of nuclear power.

There is no doubt that the Genetics Committee wanted concerned members of the public to get the message that there were no safe doses of radiation. Report authors cleverly reminded readers that they may never see evidence of harm; the genetic damage could be a hidden risk passed on to children and grandchildren that might not show up for several generations into the future. That facet of the “no safe dose” model has made it a difficult myth to refute via experimentation.

This quote is from the last page of the three page reprint of the report in the New York Times.

The basic fact is–and no competent persons doubt this— that radiations produce mutations and that mutations are in general harmful. It is difficult, at the present state of knowledge of genetics to estimate just how much of what kind of harm will appear in each future generation after mutant genes are introduced by radiations. Different geneticists prefer differing ways of describing this situation: But they all come out with the unanimous conclusion that the potential danger is great.
…
We ought to keep all of our expenditures of radiation as low as possible. Of the upper limit of ten roentgens suggested in recommendation C, we are at present spending about one-third for medical x-rays. We are at present spending less–probably under one roentgen–for weapons testing. We may find it desirable or even almost obligatory that we spend a certain amount on atomic power plants. But we must watch and guard all our expenditures. From the point of view of genetics, they are all bad.

Emphasis added.

With such categorical statements of the unavoidable harm, one might think that the committee members held clear and convincing experimental or epidemiological evidence supporting their conclusions. That is not the case here; the primary evidence for the assertion that all doses of radiation, no matter how small, can cause mutations came from experiments on short-lived insects and annual plants.

Even that evidence was either inconclusive or contradictory in the low dose regions3 of interest to people in nuclear medicine or nuclear energy production.

Irradiation experiments had been performed on mice and rats, but they did not provide any evidence of inheritable mutations. They also did not provide evidence of life shortening effects of with doses below 1 mGy per day.

The genetics committee members acknowledged the scant data upon which they based their recommendations deep in the body of their report, but in the introduction and conclusion–parts that many busy people read first–they expressed great confidence and used assertive language like the “no competent persons doubt this” statement highlighted in the above quote.

Aware of Exaggerations

Dr. Ed Calabrese has even uncovered evidence that the geneticists were aware of the fact that they were exaggerating the risk. Here are quotes from copies of correspondence among committee members that he shared with me.

From Failla to Weaver March 5, 1956 “Every effort should be made to avoid creating the impression that the problem is being presented in an exaggerated way. This is a case in which judicious understatements may be most effective. (For one thing, they cannot be attacked.) Such an impression could be created not only by what is said and how it is said, but also by what is omitted.”

From Demerec to Dobchansky Aug 9, 1957 (after the initial report, but during preparation of the more detailed document) “I, myself, have a hard time keeping a straight face when there is talk about genetic deaths and the tremendous dangers of irradiation. I know that a number of very prominent geneticists, and people whose opinion you value highly, agree with me.”

From Dobchansky to Demerec Aug 13, 1957 “Let us be honest with ourselves — we are both interested in genetics research, and for the sake of it are willing to stretch a point when necessary. But let us not stretch it to the breaking point! Overstatements are sometimes dangerous, since they result in their opposites when they approach the levels of absurdity.

Now, the business of genetic effects of atomic energy has produced a public scare, and a consequent interest in and recognition of the importance of genetics. This is to the good, since it will make some people read up on genetics who would not have done so otherwise, and it may lead to the powers-that-be giving money for genetic research which they would not give otherwise.”

Rockefeller Foundation Influences

Though several of the sixteen committee members accepted the “target theory” that assumed a linear proportionality between radiation dose, DNA damage and inheritable genetic effects, there were some quarrels among the committee members. However, the assigned chairman of the committee, Dr. Warren Weaver, was a skilled facilitator in a strong position to encourage agreement. He was the director of the Division of Natural Sciences for the Rockefeller Foundation from 1932-1959. In that position he was responsible for approving all foundation grants in the areas of molecular biology and genetics.

Weaver was the “powers-that-be” who could provide–or not provide–the research resources the geneticists were interested in obtaining. Several of his committee members were also his grantees, including the influential, Nobel Prize-winning Hermann Muller.

For several years following the issuance of the BEAR 1 report, committee members and various Rockefeller Foundation-supported researchers worked hard to spread the idea that there are no safe doses of radiation. Their effort helped to fertilize the seeds of doubt about nuclear energy that the committee carefully planted. Here’s an example from Nov 15, 1956.

Warning against nuclear power by Rockefeller Foundation

The growing apprehensions contributed to a number of expensive regulatory requirements and set the stage for a focused movement to oppose all efforts to develop nuclear energy. It established a precedent among opponents of radiation-related technologies for listing various effects of intense radiation and implying that those effects occur at even the lowest possible dose.

It was no real surprise to learn that this effort to erect costly, fear-based barriers to the development of atomic electrical power and ship propulsion was entirely funded by the Rockefeller Foundation. Though some observers claim that the Foundation severed ties with the Rockefeller Family in the 1920s, there is historical evidence of sustained family involvement (page 9 of previous link) and interest in the projects that the Foundation chose to fund.

Just imagine the difference in our current lives if the Thomas Watson Foundation had been praised for funding a study that asserted the risk of an end to the human race if personal computers were developed without strict exposure limits and multiple layers of safety features preventing the dire risks of carpal tunnel syndrome and eye strain.

The Rockefeller Foundation reduced its funding for radiobiology beginning in the early 1960s and eliminated it completely by 1970. I suspect they were quite pleased with the status quo at that time and were not interested in helping to fund new research that might have provided an earlier, better understanding of the actual health effects of low dose radiation to humans.

Additional key excerpts from pages 2-2 – 2-7 are quoted below

When the daily tolerance dose of 0.1 r was adopted, it was thought that this was a conservative value, involving a large factor of safety. Observation of persons occupationally exposed to radiation within this limit has revealed no deleterious effects of any kind attributable to radiation. However, the period of observation is not yet sufficiently long to be sure that exposure at this rate can be continued safely throughout life. The results of large scale experiments with mice and rats (and more limited experiments with other animals) lead to the conclusion that probably the factor of safety involved in the daily tolerance dose of 0.1 r, is not as large as it was though at first. From the genetic point of view a revision downward is indicated because of the larger percentage of the total population now being exposed to radiation.
…
There are also potent psychological factors that increase the fear of radiation injury beyond justifiable boundaries. These are based mainly on the tragic experience of the early workers with radiation and the effects of the atomic bomb on the Japanese — both of which have been dramatically publicized. All of these factors help to create an atmosphere of mystery around the radiation protection problem and promote skepticism on the part of those not familiar with radiation effects. It may be well, therefore, to point out some pertinent facts.

The detailed mechanism of the action of ionizing radiation on the living cell is not known. This statement, which is often made, leads the uninitiated to think that if “nothing” is known about the “mechanism” very little indeed must be known about the effects of radiation on man. One should bear in mind the sharp distinction between knowing what happens and explaining how it happens. Nobody knows what life is or how it originated, but a great deal is known about the human body and its behavior in health and disease.


To give a homely example, many people can be good drivers without knowing anything about the mechanism of the automobile engine.


There is at present a large body of information about the effects of radiation on living organisms and on man. Every living cell can be damaged and killed by radiation if the dose delivered to it is large enough. Many different kinds of effect have been observed and studied. All such effects can be produced by any type of ionizing radiation provided it reaches the cell or organ in sufficient amount. Thus there is no uniqueness about any one type of ionizing radiation as to the kind of effect it will produce, although there is in some cases a difference in the dose required to produce a certain degree of effect by two different types of radiation. This is important because most of our information has been obtained from work with x-rays and can, therefore, be applied to other types of ionizing radiation by making suitable modifications of dosage. Even when the relative biological effectiveness is not known, one can make a conservative estimate of it to be on the safe side in the protection of personnel.

The advantage of being able to make use of the large body of information obtained with x-rays is very great. This type of radiation has been used extensively for the diagnosis and treatment of disease in man for about 50 years. Many doctors and technicians have been continually exposed to it for years. Some have suffered injuries of various types and degrees, leading to premature death in some instances, and some have shown no ill effects. There is, therefore, a very large background of practical experience based on observations made on human beings. In addition, there is, of course, a vast amount of information derived from experiments on laboratory animals and other living organisms.

As a matter of principle it is sound to avoid all unnecessary exposure to ionizing radiation, because it is desirable not to depart from the natural conditions under which man has developed by evolutionary processes. However, man has always lived in a field of ionizing radiation due to the presence of radioactive material in the earth and to cosmic rays. Whether exposure to this level of radiation is beneficial or deleterious to man (and the race) is a matter of speculation. The obvious fact is that it cannot be avoided and it is, therefor, normal for man to live in this environment. We have then a lower limit of continuous exposure to radiation that is (unavoidably) tolerated by man. There is, on the other hand, a much higher level of exposure that is definitely known to be harmful. In between these two extremes there is a level of exposure, — in the neighborhood of 0.1 r/day — which all experience to date show to be safe, but the time of observation of large numbers of people exposed at this rate under controlled conditions, is too short to permit a categorical assertion to this effect. It should be noted in this connection that lowering the level of exposure by a factor of two (as recommended later in this report) or even ten, does not alter the situation materially, insofar as making a positive statement of absolute safety is concerned. In strict scientific language, the only statement that can be made at the present time about the lifetime exposure of persons to penetrating radiation at a level considerably higher than the background radiation level is that appreciable injury manifestable in the lifetime of the individual is extremely unlikely. Furthermore, on the basis of present knowledge it may be expected that if there should be any injury, it would manifest itself only in the most susceptible individuals. Obviously, the closer the level of exposure approaches background level, the greater the probability that no injury at all will occur.
…
No matter what effect (e.g. body weight, blood count changes) — observable in the individual — has been studied by animal experiments, statistically significant differences have been obtained only when the daily dose has been considerably greater than 0.1 r. In the range of 0.1 r/day the differences may be plus or minus, which means that, if there is a difference at all, it must be small. Even if a small unfavorable difference were to be established by careful experiments using very large numbers of animals, the question would still remain as to whether the result is applicable to man. There is for one thing a big difference in the normal life span of man and laboratory animals and the problem of chief concern is one in which periodic exposure throughout adult life is involved. A daily dose that produces a given effect in measurable degree in rats may or may not produce the same degree of effect in man. The effect may be more marked ot it may be less marked. Before the results of animal experiments can be extrapolated to man, it is necessary to derive certain generalizations that apply at least to different species of mammals, including animals with a long life span.
…
Permissible dose

The concept of a tolerance dose involved the assumption that if the dose is lower than a certain value — the threshold dose — no injury results. Since it seems well established that there is no threshold dose for the production of gene mutations by radiation, it follows that strictly speaking there is no such thing as a tolerance dose when all possible effects of radiation on the individual and future generations are included. In connection with the protection problem the expression has been used in a more liberal sense, namely to represent a dose that may be expected to produce only “tolerable” deleterious effects, if they are produced at all. Since it is desirable to avoid this ambiguity the expression “permissible dose” is much to be preferred.

It is now necessary to give this expression a more precise meaning, irrespective of what values of the permissible dose will be recommended in this report. In the first place it is well to state explicitly that the concept of a permissible dose envisages the possibility of radiation injury manifestable during the lifetime of the exposed individual or in subsequent generations. However, the probability of the occurrence of such injuries must be so low that the risk would be readily acceptable to the average normal individual. Permissible dose may then be defined as the dose of ionizing radiation that causes no appreciable bodily injury to the average normal individual at any time during his lifetime. As used here, “appreciable bodily injury” means any bodily injury or effect that the average normal person would regard as being objectionable and/or competent medical authorities would regard as being deleterious to the health and well being of the individual.
…
Permissible Weekly Dose

Permissible weekly dose is the weekly dose of ionizing radiation that the average normal person may receive for the rest of his life without suffering appreciable bodily injury at any time during his lifetime.
