Samples of algae were ashed, and the radioactivity in the ash was determined by counting on a MST-17 end-window counter. A potassium standard was used to convert relative activities to absolute values. The potassium in the ash was determined quantitatively by the cobalt-nitrite method. It was found that the radioactivity in Cystoseira barbata significantly exceeded the natural activity due to potassium. Aluminum absorption studies on the ash of this algae indicated the existence of Sr/sup 90/-Y/sup 90/ in the ash. A sample of Cystoseira barbata gathered in 1953 was secured from a local museum and analyzed. It showed only the presence of K/sup 40/. Other samples of Cystoseira barbata from the Sevastopol Biological Station which were gathered in 1939 and 1949 indicated the absence of fission products in the ash. The radioactivity in the ash of the other algae present was due to the presence of K/sup 40/. (TTT)
