Biogeochemical Studies of Long-Lived Radionuclides in Marine Environments

摘要

Research results from several studies relevant to seabed dispoal of radioactive wastes are briefly discussed. The studies include: (1) mobilization of plutonium from Enewetak and Bikini lagoon sediments to seawater; (2) concentrations of sup 90 Sr, sup 137 Cs, /sup 239+240/Pu, sup 241 Am, sup 207 Bi and sup 210 Pb- sup 210 Bi- sup 210 Po in fish from the Marshall Islands; and (3) plutonium in northeast Atlantic sediments.
