• Previous findings in regard to radioactive contamination of fish varied among workers as to kinds, amounts and routes of radioactive elements transferring into different tissues of fish. In the present experiments one of two groups of the gold fish, Carassius autratus, each measuring 2cm. in the length, was reared for periods from one to 264 hours in water containing either one of the folowing isotopes at various concentrations, P32, S35, Ca45, or Sr89. The other, having been left without food for ten days, was reared for the same length of time in the presence of algae, Spirogyra radioactivated with the above isotopes. Radioactivity absorbed directly from the water is indicated in the ratio of the activity of ashed tissues against that of the water, and the activity transferred through the algae, in the ratio against the algae (Tables 1, 2; Figures 2, 3). Of the isotopes taken by the fish of the former group, Ca45 and Sr89 showed the counts, in most cases, stronger than P32 and S35, with the gill giving off the highest count of all the organs examined; while in the latter group, vice versa. The fact that P32 and S35 were more easily transferred into the digestive organs of the latter fish than Ca45 and Sr89 may be explained in the light of findings from electropherogram exmination of the radioactive algae that P32 and S35 were absorbed in higher molecule compounds, whereas the others found in ionic form in the algae.
