Dust concentrations of 21 study of personal inhalation exposure. .mu..g m/sup -3/ and sea spray of 34 ..mu..g m/sup -3/ were the background throughout the Bikini Island except within 50 m of the windward beach. Background concentrations of /sup 239 +240/Pu were 60 aCi m/sup -3/ in the coconut grove and 264 aCi m/sup -3/ over rain-stabilized bare soil. The ratio of plutonium activity in’ aerosols relative to the activity in underlying soil, defined as the enhancement factor, EF, was typically less than one. Enhancement factors increased about 3.8 as a result of tilling. Plutonium resuspension flux was estimated at 0.49 pCi m/sup -2/ year/sup -1/ over most of Bikini Island. Aerosol size distributions associated with mass and with plutonium activity were typically log-normal with median aerodynamic diameter 2.44 ..mu..m, which decreased to 2.0 ..mu..m above freshly tilled soil. The Pu concentration in aerosols collected over disturbed soil increased by a factor of 19.1. Vehicular traffic produced dust pulses typically of 10 s duration, concentration, 28 ..mu..g m/sup -3/ average and plutonium enhancement factor 2.5. Personal dosimetry showed that enhancement of dust by a worker was a factor of 2.64 for heavy work outdoors and 1.86 for light work in and around houses. Pulmonary deposition of plutonium was calculated for various exposure conditions. The pulmonary deposition ranged from 1476 aCi h/sup -1/ to 12 aCi h/sup -1/ with intermediate values for heavy outdoor work and for light work in and around houses. ; Major Descriptors: *LUNGS -- RADIATION DOSES; *PLUTONIUM 239 -- PARTICLE RESUSPENSION; RADIOACTIVITY *PLUTONIUM 240 -- PARTICLE RESUSPENSION; *SOILS -- Descriptors: BIKINI; DEPOSITION; DUSTS; EXPERIMENTAL DATA; INHALATION; ISOLATED VALUES; MAN; RADIOACTIVE AEROSOLS Broader Terms: ACTINIDE ISOTOPES; ACTINIDE NUCLEI; AEROSOLS; ALPHA DECAY RADIOISOTOPES; ANIMALS; BODY; COLLOIDS; DATA; DATA FORMS; DISPERSIONS; DOSES; EVEN-EVEN NUCLEI; EVEN-ODD NUCLEI; HEAVY NUCLEI; INFORMATION; INTAKE; ISLANDS; ISOTOPES; MAMMALS; MARSHALL ISLANDS; MICRONESIA; NUCLEI; NUMERICAL DATA; OCEANIA; ORGANS; PLUTONIUM ISOTOPES; PRIMATES; RADIOISOTOPES; RESPIRATORY SYSTEM; SOLS; VERTEBRATES; YEARS LIVING RADIOISOTOPES Subject Categories: 510301* -- Environment, Materials Monitoring & Transport -- Soil Terrestrial -- Radioactive -- (-1987) 560171 -- Radiation Effects -- Nuclide Kinetics & Toxicology -- Man --~ 560161 500300 -- Radionuclide Effects, Kinetics, & Toxicology -- Man -- Environment, Atmospheric -- Radioactive Materials Monitoring & Transport -- (-1989) INIS Subject Categories: B31* C21 -- -- Land Tissue Distribution, Radionuclides B33 -- Atmosphere Metabolism, Toxicology & Removal of 10/5/912 (Item 612 from file: 103) 00606502 ERA-05-016582; INS-80-005857; EDB-80-046025 Title: Alpha-sensitive cellulose nitrate track detectors: the study of environmental contamination Author(s): Buddemeier, R.W.
