Subfile: GAP (General and Practical); TIC (Technical Information Center). Country of Origin: United States Country of Publication: United States ; Abstract: Between 1946 and 1958, the United States conducted 66 nuclear tests in the Pacific atolls of Eniwetok and Bikini in the Marshall Islands. Since 1972, LLNL has conducted a variety of studies related to the cycling and transport of longer lived residual radionuclides in the marine environments of these atolls. The primary concern is to collect sufficient data to develop recommendations to minimize the transfer of man-made radionuclides to people returning to the atolls. However, an attempt has also been made to relate analytical findings to much wider fields of scientific endeavor and to develop models that are useful, first locally, and secondly in another aquatic environments receiving inputs from different source terms. One such program deals with the behavior of plutonium radionuclides in the marine environment of Eniwetok and Bikini, the findings of which are reported. A summary of the concentration of /sup 239/Pu plus /sup 240/Pu in the Eniwetok and Bikini lagoons and in the North Equatorial Pacific Ocean is presented.; Major Descriptors: *BIKINI -- RADIATION MONITORING; *ENIWETOK -- RADIATION MONITORING; *PACIFIC OCEAN -- RADIATION MONITORING; *PLUTONIUM 239 -RADIOACTIVITY; *PLUTONIUM 240 -- RADIOACTIVITY Descriptors: MARINE SURVEYS; MARSHALL ISLANDS; PLUTONIUM; RADIOACTIVE WASTES; RADIONUCLIDE MIGRATION; SEAWATER; SEDIMENTS; WATER POLLUTION Broader Terms: ACTINIDE ISOTOPES; ACTINIDE NUCLEI; ACTINIDES; ALPHA DECAY RADIOISOTOPES; ELEMENTS; ENVIRONMENTAL TRANSPORT; EVEN-EVEN NUCLEI; EVEN-ODD NUCLEI; HEAVY NUCLEI; HYDROGEN COMPOUNDS; ISLANDS; ISOTOPES; MARSHALL ISLANDS; MASS TRANSFER; MATERIALS; METALS; MICRONESIA; MONITORING; NUCLEI; OCEANIA; OXYGEN COMPOUNDS; PLUTONIUM ISOTOPES; POLLUTION; RADIOACTIVE MATERIALS; RADIOISOTOPES; SEAS; SURFACE WATERS; SURVEYS; TRANSURANIUM ELEMENTS; WASTES; WATER; YEARS LIVING RADIOISOTOPES Subject Categories: 520301* -- Environment, Aquatic -- Radioactive Materials Monitoring & Transport -- Water -- (1987) 10/5/858 00690104 (Item 558 from file: 103) GAP-80-018652; EDB-80-129634 Title: Marshall Islands project Title: Energy and technology review Publication Date: Oct 1980 p 2-7 UCRL-52000-80-10 Document Type: Analytic of a Report Language: English Journal Announcement: EDB8012 Availability: NTIS, PC A03/MF AOl. Subfile: GAP - (General and Practical); TIC (Technical Information Center). Country of Origin: United States Country of Publication: United States Abstract: At the end of World War II, the US entered into a Trust Territory Agreement with the six districts of Micronesia, thereby accepting responsibility for the welfare and education of their people. In 1947, the people of the Enewetak and Bikini Atolls (in the Marshall Islands) were relocated to other islands so that the US could conduct nuclear tests there. In response to requests from the people for permission to return to their atolls and in anticipation of the termination of the Trust Territory Agreement in 1981, a series of field surveys and assessment studies have been conducted under the technical direction of LLNL. These studies are designed to estimate potential radiation doses and to allow the US government to make reasonable recommendations on 9008801 Report Number(s):
