The United States Atomic Energy Commission, established by the Atomic Energy Act of 1946, sponsored experiments between 1945 and 1947 where 18 patients “received injections of plutonium as a part of efforts to calibrate body burdens… The researchers did not expect that the patients would receive any therapeutic benefits from the plutonium they received and made a deliberate effort to prevent them from learning about their unwitting participation in the experiments” (p. 16).
In this interview, Dr. Chris Busby explains how the current dominant model of radiation risk was formed.
Therefore, the physicists involved in producing the model essentially “turn[ed] a person into a bag of water and then they said that the exposures had to be regulated on the basis of the amount of energy that was transmitted into the bag of water”
“Put a thermometer inside it”
“Fire radiation at it and you see if the temperature goes up”
“And that enables you to define absorbed dose”
Busby concludes: “ICRP was there to kind of like control the understanding of risk and they still are, they still are”
