The importance of this new finding is that it completely changes the scheme of radiation doses which the Japanese bomb survivors are supposed to have received, especially in Hiroshima. The new research has revealed that most of the cancer caused by the atomic bombs came from gamma rays--and not from fast neutrons-suggesting that gamma radiation is much more hazardous than was previously believed. The film badges worn by some atomic veterans recorded only gamma radiation. David Auton, a physicist in the office of target and damage assessment of the Defense Nuclear Agency (DNA)--and who accompanied General Harry Griffith at the April 6th Senate hearing--has stated his concern about the new findings with the Japanese A-bomb studies. In an interview in the May 22nd, 1981 Science, Auton stated, "The implications are far reaching for health regulation and nuclear power in this country in general." More recently, Dr. Edward Radford, professor of environmental epidemiology at the University of Pittsburgh and former chairman of the BEIR-3 Committee, has sharply criticized the Japanese studies which serve as the basis for the National Academy of Science's BEIR-3 report. In a March 18th, 1983 New York Times article entitled "Health Expert Finds Hazard of Radiation Worse Than Feared," Radford said that the new research on the Japanese A-bomb victims shows that the radiation damage was ten times worse than previously indicated. In conjunction with these recent developments in radiation studies, it should be noted that since at least 1978 the federal
