Specific isotopes are associated with particular organisms and tissues. Of the long-lived fission products--Sr/sup 90/, Cs/sup 137/ and Ce/sup 144/--only Ce/sup 144/ is present in ma rine organisms in significant amounts. Of the induced radioisotopes, Fe/sup 55,//sup 59/, Zn/sup 65/, Co/sup 57,//sup 58,//sup 6/ /sup 0/, and Mn/sup 54/ contribute up to 100 per cent of the radioactivity in marine animals but practically none of the radioactivity in marine algae. Oceanic fish differ from reef fish in that Zn/sup 65/ ranks first with the ocean fish and Fe/sup 55/ for the reef fish. Plankton in comparison with fish have greater amounts of Co/sup 60/ and lesser amounts of Fe/sup 55/. The distribution of radioisotopes in terrestrial plants and animals from the same geographical area is greatly different than the distribution in marine organisms. (auth)
