(Tokyo) (Japan) Publication Date: 1955 p 90-92 Document Type: Journal Article Language: English Coden: . Journal Announcement: EDB8101 Subfile: TIC (Technical PMGTA ‘ Information Center). Country of Origin: Japan Abstract: Sea water collected around the Bikini Atoll from July to September 1954, was analyzed for total radioactivity by adding 2 g solid NH/sub 4/Cl, g/l), 1 ml of an aqueous solution of Ferric alum (86.3 and 1 ml of BaCl/sub 2/ solution (17.8 g/l) to 1 1 of H/sub 2/0 heated to 60 to 70 while being stirred. NH/sub 4/0H was added until the solution was faintly pink to phenolphthalein. After 2-min boiling the precipitate settled on standing for several hours at room temperature before being filtered on a filter disk lain above a glass filter. Counting rates of 2.1 +- 1.6 to 140.8 +- 6.8 counts/min/1 were obtained.; Major Descriptors: *SEAWATER -~ RADIOACTIVITY Descriptors: AMMONIUM CHLORIDES; AMMONIUM HYDROXIDES; BARIUM CHLORIDES; BIKINI; FILTRATION; JAPAN; SAMPLING; SEAS; SEPARATION PROCESSES Broader Terms: ALKALINE EARTH METAL COMPOUNDS; AMMONIUM COMPOUNDS; AMMONIUM HALIDES; ASIA; BARIUM COMPOUNDS; CHLORIDES; CHLORINE COMPOUNDS; HALIDES ; HALOGEN COMPOUNDS; HYDROGEN COMPOUNDS; HYDROXIDES; ISLANDS; MARSHALL ISLANDS; MICRONESIA; OCEANIA; OXYGEN COMPOUNDS; SEPARATION PROCESSES; SURFACE WATERS; WATER Subject Categories: 520301* -- Environment, Aquatic -- Radioactive Materials Monitoring & Transport -- Water -- (1987) 450200 -- Military Technology, Weaponry, & National Defense -- Nuclear Explosions & Explosives 10/5/842 (Item 542 from file: 00703806 EDB-81-012056 Author(s): Yatazawa, Subfile: TIC 103) Title: Radioactive contamination of plants in Japan covered with rainout from H-bomb detonations in March-May 1954 at Bikini Atoll, Marshall Island. Part II. Radioactive elements of contaminated plants v1. (Technical Information Center). Country of Origin: Japan Coden: SPFOA ow Abstract: Following a fallout estimated at 0.2 microcurie/1l, Trifolium repens, Astragalus sinicus, and Rumex japonicus were harvested and analyzed for radioactivity. Most of the radioactivity (2300 to 4700 counts/min/50 g plant ash) was associated with oxalate precipitate. A small amount of activity in the Zn group is attributed to /sup 65/Zn produced by reaction /sup 64/Zn (n,..gamma..) from Zn employed in the mechanical parts of the bomb. Sr-Ba radioactivity was 0.1 that of the rare earth group. Distribution of the radioactive elements was nearly the same as that found on the No. 5 Fukuryu-Maru.; Major Descriptors: *BARIUM -- UPTAKE; *NUCLEAR EXPLOSIONS -- FALLOUT; *PLANTS -- RADIOACTIVITY; *RARE EARTHS -- UPTAKE; *STRONTIUM -- UPTAKE; *ZINC 65 -- UPTAKE : Descriptors: BIKINI; CONTAMINATION; JAPAN; ZINC 64 Broader Terms: ALKALINE EARTH METALS; ASIA; BETA DECAY RADIOISOTOPES; BETA-PLUS DECAY RADIOISOTOPES; DAYS LIVING RADIOISOTOPES; ELECTRON CAPTURE RADIOISOTOPES; ELEMENTS; EVEN-EVEN NUCLEI; EVEN-ODD NUCLEI; EXPLOSIONS; INTERMEDIATE MASS NUCLEI; ISLANDS; ISOTOPES; MARSHALL ISLANDS; METALS; MICRONESIA; NUCLEI; OCEANIA; RADIOISOTOPES; STABLE 9003992 M.
