THE ROLE OF DETRITUS FORMATION IN THE MIGRATION OF Sr$sup 90$, Cs$sup 137$, AND Ce$sup 144$. EXPERIMENTS WITH THE SEAWEED CYSTOSEIRA BARBATA (in Russian)
Knowledge of the effect of decaying matter on the movement of fission products is of importance in the disposal of fission product wastes at sea. Duplicate experiments were run on a 2.5-liter scale with 10 mu c/l of Sr/sup 90/ Cs/sup 137/, and Ce/sup 144/ tracers in the presence of the brown algae Cystoseira barbata which is the most common algae in the Black Sea. Since the sea water was not circulated or aerated, the algae began to die in four days and were completely decomposed at the end of the experiment (64 days). Activity measurements on the organic detritus showed that Sr/sup 90/ was almost completely leached from the organic matter by the sea water, but that additional amounts of Cs/sup 137/ and Ce/sup 144/ were adsorbed by the decayed organic residue from the sea water.
