neat, SGphead Gave EET Se AS inherent in a greatly expanded atomic energy industry. There constantly recurs through the report the idea that all is well today but for the future let us be very careful indeed. In summary, the report was totally reassuring as regards nuclear weapons testing, it did not attempt to face up to the problems of an atomic war, and finally it was preoccupled with the potential hazards inherent itn a developing era of large scale atomic power, Summary Report of the Committee on Genetic Effects This Committee consisted of geneticists, one authority o radiation pathology, one authority on radiological physics and radiation hazard control, and a mathematician, Dr. Warren Weav of the Rockefeller Foundation, who chaired the group. They considered the genetic effects against the backgrou of present knowledge concerning radiation as a cause of mutati in microorganisms, plants, insects, and mice, bearing in mind tendency of modern civilization to conserve all human life whe perfect or imperfect. They call attention to the perhaps grea importance of mutations which are relatively Inapparent such a defects in resistance to disease processes, decreased fertilit and curtailed life span, and impaired physical and mental vigo The more dramatic mutations, monsters, still births, and early developmental defects leading to abortion and miscarriage are not apt to be passed on to another generation. The apparently relatively negative results of the genetics survey of the survivors! first generation at Hiroshima and Nagasaki serve to emphasize the validity of this point of view, This study demonstrated that with the methods used and the radiation dosa received, the heavily irradiated surviving population was not sufficiently large for it to be possible to demonstrate a ~6 - Enclosure II
