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
