Complete fission product analyses of samples collected at Eniwetok and Bikini Atolls indicate that non-fission-product radionuclides may account -for more than half of the total activity in some fish; zn®5 contributes one- fourth or moreofthe total activity in shark muscle as determined by radio- x ; soe 3% a oA itt chemical analysis and confirmed by following the decay.
