Country of Origin: United States Country of Publication: United States Abstract: Inventories of plutonium radionuclides greatly in excess of global fallout levels persists in the benthic environments of Bikini and Eniwetok Atolls. It now appears that the atolis have reached a chemical steadystate condition with respect to the partitioning of /sup 239 +240/Pu between solution and solid phases of the environment. The mobilized /sup 239 +240/Pu has solute-like characteristics, passes rapidly and readily through dialysis membranes, has adsorption characteristics similar to those of fallout plutonium in the open ocean, and exists in solution primarily as some oxidized +5 or +6 chemical species. Water-column profiles of /sup 239 +240/Pu taken outside the atolls show a plutonium excess in the deep water mass. This remobilized /sup 239 +240/Pu possibly originates from the contaminated Major Descriptors: *PLUTONIUM 239 -- ENVIRONMENTAL TRANSPORT; *PLUTONIUM 240 -- ENVIRONMENTAL TRANSPORT; *SEAWATER -- RADIONUCLIDE MIGRATION; *SEDIMENTS -- RADIONUCLIDE MIGRATION Descriptors: BIKINI; DATA COMPILATION; DISSOLUTION; ENIWETOK; EQUILIBRIUM; FALLOUT; LIQUIDS; PACIFIC OCEAN; PHASE STUDIES; RADIATION MONITORING; SOLIDS; STEADY-STATE CONDITIONS; TABLES; UPWELLING Broader Terms: ACTINIDE ISOTOPES; ACTINIDE NUCLEI; ALPHA DECAY RADIOISOTOPES; DATA; DATA FORMS; ENVIRONMENTAL TRANSPORT; EVEN-EVEN NUCLEI; EVEN-ODD NUCLEI; FLUIDS; HEAVY NUCLEI; HYDROGEN COMPOUNDS; INFORMATION; ISLANDS; ISOTOPES; MARSHALL ISLANDS; MASS TRANSFER; MICRONESIA; MONITORING; NUCLEI; NUMERICAL DATA; OCEANIA; OXYGEN COMPOUNDS; PLUTONIUM ISOTOPES; RADIOISOTOPES; SEAS; SURFACE WATERS; WATER; YEARS LIVING RADIOISOTOPES Subject Categories: 520301* -- Environment, Aquatic -- Radioactive Materials Monitoring & Transport -- Water -- (1987) 520302 -- Environment, Aquatic -- Radioactive Materials Monitoring & Transport -- Aquatic Ecosystems & Food Chains -- (-1987) INIS Subject Categories: B32* -- Water C22 -- Radionuclide Ecology 10/5/924 (Item 624 from file: 103) 00558474 AIX-10-432891; EDB-79-137940 Title: Determination of transuranium elements in a so-called ‘Bikini sample and in marine sediment samples collected near Bikini Atoll ash’ 9004 0349 sediments previously deposited on the outer slopes of the atolls and surrounding basins.; ~
