Concentrations in liver always exceeded those in bone and concentrations were lowest in the muscle of all fish analysed. A progressive discrimination against sup (239+240)Pu was observed at successive trophic levels at all atolls except Bikini and Enewetak, where it was difficult to conclude if any real difference exists between the average concentration factor for sup(239+240)Pu among all fish, which include bottom-feeding and grazing herbivores, bottom-feeding carnivores and pelagic carnivores from different atoll locations. The average concentration of sup(239+240)Pu in the muscle of surgeonfish from Bikini and Enewetak was not significantly different from the average concentrations determined in these fish at the other lesser contaminated atolls. Concentrations among all 3rd, 4th and 5th trophic level species are highest at Bikini where higher environmental concentrations are found. The reasons for the anomalously low concentrations in herbivores from Bikini and Enewetak are not known.; Major Descriptors: *AMERICIUM 241 -- RADIOECOLOGICAL CONCENTRATION; *PLUTONIUM 238 -- RADIOECOLOGICAL CONCENTRATION; *PLUTONIUM 239 -RADIOBCOLOGICAL CONCENTRATION; *PLUTONIUM 240 -- RADIOECOLOGICAL CONCENTRATION; *SEDIMENTS Descriptors: BIKINI; BIOLOGICAL LOCALIZATION; COMPARATIVE EVALUATIONS; ENIWETOK; EXPERIMENTAL DATA; FISHES; LEVELS; TISSUES Broader Terms: ACTINIDE ISOTOPES; ACTINIDE NUCLEI; ALPHA DECAY RADIOISOTOPES; AMERICIUM ISOTOPES; ANIMALS; AQUATIC ORGANISMS; BODY; DATA; ECOLOGICAL CONCENTRATION; EVEN-EVEN NUCLEI; EVEN-ODD NUCLEI; HEAVY NUCLEI; INFORMATION; ISLANDS; ISOTOPES; MARSHALL ISLANDS; MICRONESIA; NUCLEI; NUMERICAL DATA; OCEANIA; ODD-EVEN NUCLEI; PLUTONIUM ISOTOPES; RADIOISOTOPES; VERTEBRATES; YEARS LIVING RADIOISOTOPES Subject Categories: 520302* -- Environment, Aquatic -- Radioactive Materials Monitoring & Transport -- Aquatic Ecosystems & Food Chains -(-1987) INIS Subject Categories: 10/5/752 00867481 C22* -- Radionuclide Ecology (Item 452 from file: 103) AIX-12-641124; ERA-07-019662; EDB-82-042321 Title: Detection of cadmium radioactivity in the marine environment Author(s): Noshkin, V.E.; Wong, K.M.; Eagle, R.J.; Anglin, D.L.

Country of Origin: United States Country of Publication: International Atomic Energy Agency <IAEA> Abstract: Sediment and tissues from different marine organisms recently collected at atolls of the Marshall Islands have been found to contain measurable amounts of /sup 113//sup m/Cd previously deposited to the atolls during the testing Grounds. Cadmium-113m has mullet collected from the an area contaminated only of nuclear devices at the Pacific Proving been also detected in some internal organs of east coast of the United States of America in with global fall-out debris. This is one of the few summaries to show that this long-lived radionuclide = 14.6 years) exists and persists in the marine environment. (Tsub (1/2) It is the dominate anthropogenic radionuclide in the liver of some pelagic fish from Bikini and Enewetak Atolls and is found concentrated in other tissues and organs of all fish analysed.
