The biology and medicine progrem is primarily concerned with evaluating the extent of radiation and other atomic energy hazards, prescribing adequate protective measures for atomic energy operations and personnel, and providing related information to other Government egencies responsible for civilien and military defense. Recent weapon tests have presented special problems and opportunities in this respect, which are discussed below. , Related activities of a continuing nature are also discussed which include protection of workers in Commission installations, the development of radiation instruments for both monitoring and research uses, the study of the effects of radiation on other mammals, and provision of facilities for the application of atomic energy techniques to the study and treatment of cancer. Basic research in the epplication of atomic energy to the life sciences continues as the long-range activity. A comprehensive discussion of current research in plant sciences will be included in the forthcoming Semiannual Report to the Congress. End of UNCLASSIFIED section.) DOE ARCHIVES Weapon Test Activities = During the surzer and fall, the Commission's biology end medicine staff contributed to the planning for the BUSTHR-JANGLE series of weapon tests held in Nevaca in October end November. In eddition, in cocperation with the New York Operations Office, e progres for measuring the radioactive fall-out over the United States from the detonations ~2s planned and executed. Several related reseerch projects were elsc sronsored. Operation RANGER, carried out in January end Februery, 1951, hed demonstrated tnat the Nevede site could be used sefely for esoveground | shots such es those plenned for BUSTER, provided that the exergy relezse is not too great and weather conditicns are favoreble. The surfece and underground shots contemplated for JANGLE, however, presented new and more serious probiems of radiological safety. Tne AEC officials primarily responsible for reccxmzencsticns to the Commission as to the feesibdility of the testis met in Mey et Los Alamos enc Oe tama+ egein in Juiv 4t Washington with rerresentatives of the Armec Services, the Ceotogi ces Survey, end the Los Alemos and Sandie Leboreicries end with leading AEC ientific censultents to evaluate the potentie. contamination and Sstsblish criteria for safety. General ezreezent wes reached that both the surfece and undergrouné shots could be conducted without undue radiological tezard, but that the results of the surface shot should be closely stucied to determine that the underground shot could be carrieé out with reescnrable sefety.
