THE NEED FOR CONTINUATION OF STUDIES OF RADIATION CONTAMINATION OF BIOTIC FORMS AT THE BIKINI AND ENIWETOK TESTING GROUNDS In the years 1945-1951 inclusive, this country detonated a total of twenty-four (24) atomic bombs. were essentially tests of bomb efficiency, These detonations for even the two detonations over the Japanese cities of Hiroshima and Nagasaki were experimental models and contributed much to our understanding of the forces involved. In twenty-two of the tests the physical forces involved were evaluated and some attention paid to the immediate biological problems in as much as they constituted potential health hazards of varying degrees. Some of the tests, notably the Bikini experiments and the Eniwetok testing program in the spring of 1951, included biological testing of the effects of external exposure to neutrons and gamma rays, while only the Bikini underwater test included an exploratory phase of the effects of radiation contamination from residual fission products and induced radia- tion. The subsequent studies made after the testing program at Alamogordo, New Mexico, by the Atomic Energy Project, University of California at Los Angeles, and those at Bikini and Eniwetok for the resurveys conducted by the Commission through
