Radiobiological analysis of the reef fishes of Rongelap and Ailinginae Atolls indicated that a recontamination of the area occurred in 1956. Gross levels of beta activity in muscle tissue ranged from 0.016 to 0.038 mu c/kg wet weight. The levels of radioactivity in bone and muscle tissues of fish collected during 1957 were about the same as the levels for similar tissues collected in 1955. Gamma spectra analysis and ion-exchange methods revealed the presence of Zn/sup 65/, Co/sup 57/, Co/sup 58/, Co/sup 60/, Mn/sup 54, and Fe/sup 55/. Radiostrontium was found only in small amounts (about 0.0014 mu c/kg wet weight) in the bone of fish from Kabelle Island, Rongelap Atoll. Approximately 40 per cent of the total radioactivity in the reef fishes was due to Zn/sup 65/, 28 per cent to cobalt, 26 per cent to Fe/sup 55/, and 6 per cent to other radionuclides. (auth)
