response to a request from the Atomic Energy Commission, accepted the responsibility for studies of the effects of radiation upon aquatic forms during and subsequent to the Bikini tests. Following the Bikini tests of 1946 and the resurvey of 1947, the testing program shifted to Eniwetok where studies of biological contamination were conducted during the testing program of 1948, with follow-up resurveys during the summer of that year and also during the summer of 1949. The field studies at Bikini and Eniwetok have been summarized in the following reports furnished the Atomic Energy Commission by the Applied Fisheries Laboratory: UWFL-7 Radiobiological Resurvey of Bikini Atoll During the Summer of 1947 UWFL-16 Bikini Radiobiological Resurvey of 1948 UWFL-19 Eniwetok Radiological Resurvey, July 1948 UWFL-20 Proposed Program of Study of Radiation Biology at Bikini and Eniwetok During the Summer of 1949 UWFL-22 Suggestion for a Program of Radiological Resurvey at Bikini-Eniwetok During July and August of 1950 UWFL-23 Radiobiologicall Survey of Bikini, Eniwetok, and Likiep Atolls--July to August, 1949 UWFL-28 The Need for Continuation of Studies of Radiation Contamination of Biotic Forms at the Bikini and Eniwetok Testing Grounds UWFL-30 Biological Monitoring Program for Eniwetok Prepared for the Biomedical Test Planning and Screening Committee
