Radioisotopic analysis confirms the microclimate-estimated 1:3 to 1:20 soil to plant /sup 137/Cs dry matter concentration ratio. This ratio exacerbates the dose to man from intake of food plants. Nephelometer measurements of airborne particulates presently indicate a minimum respiratory radiological dose.; Major Descriptors: *BIKINI -- REMOTE SENSING; *ENIWETOK -- REMOTE SENSING; *FISSION PRODUCTS -- BIOLOGICAL ACCUMULATION; *FISSION PRODUCTS -ENVIRONMENTAL EXPOSURE PATHWAY; *FISSION PRODUCTS -- RADIONUCLIDE MIGRATION Descriptors: AMBIENT TEMPERATURE; CESIUM 137; CONTAMINATION; DATA COMPILATION; DUSTS; FOOD CHAINS; HUMIDITY; MOISTURE; RADIATION MONITORING; RADIOACTIVE ABROSOLS; RAIN; SOILS; SOLAR RADIATION Broader Terms: AEROSOLS; ALKALI METAL ISOTOPES; ATMOSPHERIC PRECIPITATIONS; BETA DECAY RADIOISOTOPES; BETA-MINUS DECAY RADIOISOTOPES; CESIUM ISOTOPES; COLLOIDS; DATA; DISPERSIONS; ENVIRONMENTAL TRANSPORT; INFORMATION; ISLANDS; ISOTOPES; MARSHALL ISLANDS; MASS TRANSFER; MATERIALS; MICRONESIA; MONITORING; NUCLEI; NUMERICAL DATA; OCEANIA; ODD-EVEN NOCLEI; RADIATIONS; RADIOACTIVE MATERIALS; RADIOISOTOPES; SOLS ; STELLAR RADIATION; YEARS LIVING RADIOISOTOPES Subject Categories: 510302* -- Environment, Terrestrial -- Radioactive Materials Monitoring & Transport -- Terrestrial Ecosystems & Food Chains -- (-1987) INIS Subject Categories: C22* 10/5/802 00750474 Author(s): -- Radionuclide Ecology (Item 502 from file: ERA-06-017422; Robison, Conrado, C.L.

Country of Origin: United States Country of Publication: United States Abstract: The purpose of this report is to refine the dose predictions, subsequent to the cleanup effort, for alternate living patterns proposed for resettlement of Enewetak Atoll. The most recent data developed from projects at Enewetak and Bikini Atolls for concentration and uptake of Cs, Sr, Pu, and Am were used in conjunction with recent dietary information and current dose models to predict annual dose rates and 30- and 50-y integral doses (dose commitments). The terrestrial food chain in the most significant exposure pathway - it contributes more than 50% of the total dose - and external gamma exposure is the second most significant pathway. Other pathways evaluated are the marine food chain, drinking water, and inhalation.;
