Guilty Knowledge of Radiation: From Hiroshima to Fukushima
The article discusses the history of radiation exposure from nuclear events such as the bombings of Hiroshima and Nagasaki to incidents in various countries' nuclear facilities. It highlights the contrasting beliefs about the effects of low-level radiation exposure among nuclear scientists and geneticists. The contentious viewpoints and handling of radiation risks are explored through historical events and expert opinions.

Nuclear Deniers: Guilty Knowledge of Radiation from Hiroshima to Fukushima Charles Perrow, Emeritus Professor, Yale University Visiting Professor, Stanford University
radiation from atomic bombs, nuclear processing plants, and nuclear power plants in several countries: Japan, the USA, the Soviet Union, the UK, Germany and France
The bombing of Hiroshima and Nagasaki in 1945 No Radioactivity in Hiroshima Ruin Survey Rules out Nagasaki Dangers
The bombing of Hiroshima and Nagasaki in 1945 No Radioactivity in Hiroshima Ruin Survey Rules out Nagasaki Dangers Radioactivity after atomic bomb is only 1000th of that from luminous dial watch.
1953: AEC: low-level exposure to radiation can be continued indefinitely without any detectable bodily change.

Radiation-related excess deaths: 2,850 to 3,800 Bomb death rate from immediate effects: about 200,000

While Secretary Dulles admitted that in the
1953 AEC Chair: highlight the peaceful applications of nuclear explosive devices and thereby create a climate of world opinion that is more favorable to weapons development and tests. As a DOD official put it in 1953: "The atomic bomb will be accepted far more readily if at the same time atomic energy is being used for constructive ends

As a DOD official put it in 1953: "The atomic bomb will be accepted far more readily if at the same time atomic energy is being used for constructive ends. In 1953 the State Department warned that the civilian nuclear power industry could be seriously damaged because of the mistaken impression that low-level radiation is hazardous.
1959: International Atomic Energy Association (IAEA) and the World Health Organization (WHO) agree not to release radiation effects data the other has not agreed to.

1979: Three Mile Island, Harrisburg, PA Negligible radiation declared
1979: Three Mile Island, Harrisburg, PA Negligible radiation declared 1990 Columbia University: radiation too low to account for observed increases in cancer. Stress cited.
1979: Three Mile Island, Harrisburg, PA Negligible radiation declared 1990: Columbia University: radiation too low to account for observed increases in cancer. Stress cited. 1997: University of California, Berkeley: Accident doses were positively associated with cancer incidence. Associations were largest for leukemia, intermediate for lung cancer, and smallest for all cancers combined; larger for longer than for shorter latency; and larger with adjustment for socioeconomic variables.
1987: Chernobyl, USSR Not announced for 2 days; late evacuation; no warnings on food; radiation sickness not allowed as diagnosis, etc. The radioactive cloud spread over Belarus, the Ukraine and parts of Russia, and then Europe.
Chernobyl deaths: United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR): 64 (workforce only) UN Chernobyl Forum (UNSCEAR, IAEA, WHO) 4,000 deaths among the liquidators. Another report estimates an additional 5,000 deaths among the 6 million living in the contaminated areas of Ukraine, Belarus and Russia, giving us 9,000.
Chernobyl deaths continued: Union of Concerned Scientists: 50,000 excess cancer cases and 25,000 excess deaths. Greenpeace: 200,000 Russia scientists: 950,000 premature cancer deaths
IAEA: Not victims, but survivors. Calling them victims: has led them to perceive themselves as helpless, weak and lacking control over their future. This, in turn, has led either to over cautious behavior and exaggerated health concerns, or to reckless conduct, such as consumption of mushrooms, berries and game from areas still designated as highly contaminated, overuse of alcohol and tobacco, and unprotected promiscuous sexual activity.

What if the plants behaved well? Children at highest risk. 2002 study of 8 US nuclear plants closed in 1987. Strontium 90 in milk drops sharply, as did birth defects and infant deaths.

Biggest effect is childhood leukemia (CL) Germany, 2007 study found CL twice as likely near all 16 nuclear power plants. Could not determine cause.

French 2012 study: similar results for 54 nuclear power plants. Cannot attribute to gaseous discharges.
2011: Fukushimas rosy predictions: Nuclear Energy Institute declared two months after the accident, that no health effects are expected among the Japanese people as a result of the events at Fukushima. The Fukushima Medical University in February, 2012, reported only about 29 people were expected to have doses over 10 millisieverts (mSv), and the highest recorded does was 23 mSv, well below the 100-mSv exposure level that might lead to a slight increase in cancer risk.

(Prof. at Columbia University) "In terms of the health impact, the radiation is stress of not knowing, of being relocated." (Berkeley professor) "Much of the damage was really psychological the
No point in making studies: Columbia U. radiologist: 40% of everybody will get cancer It doesn t seem to me that it s possible to do an epidemiological study that will see an increased risk.

Head of US agency on protection and measurement: There s no opportunity for conducting epidemiological studies that have any chance of success.

Head of US agency on protection and measurement: There s no opportunity for conducting epidemiological studies that have any chance of success. The doses are just too low, he said. If you were to do a proposal, it would not pass a scientific review.
British sociologist: The accident actually represent a compelling case for [nuclear power] expansion, as even these old fashioned reactors have withstood the worse that nature could throw at them.

Unit 4 spent storage pool 100 feet up in a shaky, damaged building with high radioactivity, with as much Cesium 137 as at Chernobyl.

Some doubts: the external exposures over a 90 day period were between 20 -64 times the natural background radiation, or the equivalent of 300-950 chest ex-rays.
Some doubts: the external exposures over a 90 day period were between 20 -64 times the natural background radiation, or the equivalent of 300-950 chest ex-rays. The 70,000 people who spent a year in contaminated land outside of the evacuated area were exposed to an external radioactivity 100 times higher than normal background radiation in that first year.

a child living in one village and spending about 8 hours of the day outside and 16 hours inside would be exposed to about 148 mSv in the course of a year - 100 times the natural background radiation in Japan. This contradicts the WHO report of only 10-50 mSv.

Conclusions: Fukushima not much different Atomic bomb and testing denials Secrecy surrounding Windscale and Chernobyl. Fallout from TMI more serious than allowed Multiple denials about Chernobyl Radiation from normal operation plants denied
Conclusions: Fukushima not much different Atomic bomb and testing denials Secrecy surrounding Windscale and Chernobyl. Fallout from TMI more serious than allowed Multiple denials about Chernobyl Radiation from normal operation of plants denied Vast investments at stake by weapons and power industries. Grant money to scientists for whitewashing Scientific ambiguity persists as no harm in low-level radiation is replaced by too low to measure any harm.
