Country of Origin: United States Country of Publication: United States Abstract: A radiological survey was conducted from September through November of 1978 to determine the concentrations of radionuclides in the terrestrial and marine environments of 11 atolls and 2 islands in the Northern Marshall Islands. More than 70 cistern and groundwater samples were collected at the atolls; the volume of each sample was between 55 and 100 1. The concentration of /sup 90/Sr in cistern water at most atolls is that expected from world-wide fallout in wet deposition. Except for Bikini and Rongelap, /sup 137/Cs concentrations in cistern water are in agreement with the average predicted concentrations from wet deposition. The /sup 239 +240/Pu concentrations are everywhere less than the predicted fallout concentrations except at Rongelap, Ailinginae, and Bikini where the measured and predicted concentrations are in general agreement. During the period sampled, most groundwater concentrations of /sup 90/Sr and /sup 137/Cs were everywhere higher than the concentrations in cistern water. Concentrations of the transurancies in filtered groundwater solution were everywhere comparable to or less than the concentrations in cistern water. It is concluded that the concentrations of radionuclides detected during any single period may not necessarily reflect the long-term average concentrations or the concentrations that might be observed if a lined well were extended above the surface. In any case, at all atolls the /sup 90/Sr and /sup 137/Cs concentrations in groundwater are below the concentration guidelines for drinking water recommended by the Environmental Protection Agency. The maximum annual dose rates and the 30- and 50-y integral doses are calculated for the intake of both cistern water and groundwater for each of the atolls.; Major Descriptors: *CESIUM 137 -- RADIOACTIVITY; *MARSHALL ISLANDS -- RADIATION MONITORING; *MARSHALL ISLANDS -- WATER RESERVOIRS; *PLUTONIUM 239 -- RADIOACTIVITY; *PLUTONIUM 240 -- RADIOACTIVITY; *STRONTIUM 90 -RADIOACTIVITY; *WATER RESERVOIRS -- RADIATION MONITORING Descriptors: AQUATIC ECOSYSTEMS; GROUND WATER; RADIATION DOSES; TERRESTRIAL ECOSYSTEMS Broader Terms: ACTINIDE ISOTOPES; ACTINIDE NUCLEI; ALKALI METAL ISOTOPES; ALKALINE EARTH ISOTOPES; ALPHA DECAY RADIOISOTOPES; BETA DECAY RADIOCISOTOPES; BETA-MINUS DECAY RADIOISOTOPES; CESIUM ISOTOPES; DOSES; ECOSYSTEMS; EVEN-EVEN NUCLEI; EVEN-ODD NUCLEI; HEAVY NUCLEI; HYDROGEN COMPOUNDS; INTERMEDIATE MASS NUCLEI; ISLANDS; ISOTOPES; MICRONESIA; MONITORING; NUCLEI; OCEANIA; ODD-EVEN NUCLEI; OXYGEN COMPOUNDS; PLUTONIUM ISOTOPES; RADIOISOTOPES; STRONTIUM ISOTOPES; SURFACE WATERS; WATER; YEARS LIVING RADIOISOTOPES Subject Categories: 520302* -- Environment, Aquatic -- Radioactive Materials Monitoring & Transport -- Aquatic Ecosystems & Food Chains -(-1987) 520301 -- Environment, Aquatic -- Radioactive Materials Monitoring & Transport -- Water -- (1987) INIS Subject Categories: C22* -- Radionuclide Ecology (Item 500 from file: ERA-06-019278; Author(s): Cohen, 103) INS-81-008898; EDB-81-064760 Title: In vivo measurements of exposed individuals Title: In vivo measurements of bone-seeking radionuclides. report, 1977-1980 Corporate Source: Medicine N, New York Univ., NY Publication Date: 1980 p VI.1-VI.27 Report Number(s): DOE/EV/04326-3 Document Type: Analytic of a Report Language: English Journal Announcement: EDB8105 Availability: NTIS, PC A08/MF AO1l.
