Abstract: A follow-up study has been made to assess the concentrations of /sup 239/ /sup 240/Pu and /sup 137/Cs in the marine environment of Kwajalein Atoll. Fish collected from the atoll in 1972 hadbody burdens of plutonium that were substantially higher than concentrations in similar species from locations contaminated only with global fallout. Recent results, however, indicated that Kwajalein lagoon seawater contained levels of plutonium more similar to global fallout levels found in north equatorial Pacific surface waters. No satisfactory explanation for the reported plutonium levels in fish from Kwajalein collected in 1972 could be deduced from the available data. The highest plutonium concentrations reported for the 1972 reef species of fish could expose man, through ingestion of marine foods, to a dose rate as high as 25% of the proposed EPA guideline for annual total transuranic dose rate to bone (3 mrad/yr over 70 yr). The present results show the dose rate from the marine food pathway is nearer to 0.005% of the recommended EPA value and is consistent with the view that Kwajalein Atoll contains plutonium concentrations that are expected from global fallout. The magnitude of the plutonium levels reported in fish collected from Kwajalein lagoon during 1972 was excessively high, and these results appear to be inconsistent with These results also show that other environmental data from the lagoon. concentration factors for plutonium in fish muscle and bone tissues appear to be independent of species, trophic level and location, which leads to the belief that there is a great deal of validity in the concept of a concentration factor for estimating concentrations of plutonium in fish.; Major Descriptors: *CESIUM 137; *FISHES -- PLUTONIUM; *PLUTONIUM -RADIOECOLOGICAL CONCENTRATION Descriptors: BODY BURDEN; BONE TISSUES; DOSE RATES; ENVIRONMENTAL EXPOSURE PATHWAY; GLOBAL FALLOUT; HUMAN POPULATIONS; MARSHALL ISLANDS; MUSCLES; PLUTONIUM 239; PLUTONIUM 240; RADIONUCLIDE MIGRATION; SEAFOOD; SEAWATER Broader Terms: ACTINIDE ISOTOPES; ACTINIDE NUCLEI; ACTINIDES; ALKALI METAL ISOTOPES; ALPHA DECAY RADIOISOTOPES; ANIMALS; AQUATIC ORGANISMS; BETA DECAY RADIOISOTOPES; BETA-MINUS DECAY RADIOISOTOPES; BODY; CESIUM ISOTOPES; CONNECTIVE TISSUE; ECOLOGICAL CONCENTRATION; ELEMENTS; ENVIRONMENTAL TRANSPORT; EVEN-EVEN NUCLEI; EVEN-ODD NUCLEI; FALLOUT; FISH PRODUCTS; FOOD; HEAVY NUCLEI; HYDROGEN COMPOUNDS; ISLANDS; ISOTOPES; MASS TRANSFER; METALS; MICRONESIA; NUCLEI; OCEANIA; ODD-EVEN NUCLEI; OXYGEN COMPOUNDS; PLUTONIUM ISOTOPES; POPULATIONS; RADIOISOTOPES; TISSUES; TRANSURANIUM ELEMENTS; VERTEBRATES; WATER; YEARS LIVING RADIOISOTOPES Subject Categories: 520302* -- Environment, Aquatic -- Radioactiwe Materials Monitoring & Transport -- Aquatic Ecosystems & Food Chains -- (-1987) 053000 560172 Animals -- Nuclear Fuels -- Environmental Aspects -- Radiation Effects -- Nuclide Kinetics & Toxicology --- (-1987) INIS Subject Categories: C21* -- Tissue Distribution, Metabolism, Toxicology & Removal of Radionuclides 10/5/898 00639758 (Item 598 from file: 103) ERA-05-026340; EDB-80-079283 Title: Bikini scientific resurvey.
