sp. gr. 2.42. These granules were composed of unit particles which were cubic or spindle of 0.1 to 3. ..mu.. in size. The Bikini dust was calcite as determined by electron microdiffraction and x-ray diffraction studies. The coral reef is aragonite. It is suggested that coral reef was evapd. by the H-bomb explosion. ; Major Descriptors: *FALLOUT -- CRYSTAL STRUCTURE; *FALLOUT -- STRUCTURAL : CHEMICAL ANALYSIS ELECTRON DUSTS; CORALS; COLLOIDS; CALCITE; BIKINI; : ARAGONITE; Descriptors MICROSCOPY; NUCLEAR EXPLOSIONS; PARTICLE SIZE; X-RAY DIFFRACTION Broader Terms: ALKALINE EARTH METAL COMPOUNDS; CALCIUM CARBONATES; ‘CALCIUM COMPOUNDS; CARBON COMPOUNDS; CARBONATES; CNIDARIA; COHERENT SCATTERING; DIFFRACTION; DISPERSIONS; EXPLOSIONS; ISLANDS; MARSHALL ISLANDS; MICRONESIA; MICROSCOPY; MINERALS; OCEANIA; OXYGEN COMPOUNDS; SCATTERING ; SIZE Subject Categories: 500300* -- Environment, Atmospheric -- Radioactive Materials Monitoring & Transport -- (-1989) 450200 -- Military Technology, Weaponry, & National Defense -- Nuclear Explosions & Explosives 10/5/888 00651734 (Item 588 from file: EDB-80-091259 103) Title: Radioautographic studies of the radioactive ashes obtained from the No. 5 Fukuryu Maru Author(s): Kikuchi, T.; Akagi, H.; Goto, H.; Wakisaka, G.

Country of Origin: Japan Abstract: Radioautographic studies have been made of the radioactive ashes obtained from the ship by use of x-ray film, radioautographic stripping plates, and plates of ..cap alpha..-emitters. The radioactivity was found not proportional to the size of the particle, and the distribution of radioactivity in each particle was not uniform.; Major Descriptors: *FALLOUT -- AUTORADIOGRAPHY Descriptors: ALPHA DECAY RADIOISOTOPES; ASHES; BIKINI; NUCLEAR EXPLOSIONS; PARTICLE SIZE; PHOTOGRAPHIC FILMS; RADIOACTIVITY; SPATIAL DISTRIBUTION Broader Terms: DISTRIBUTION; EXPLOSIONS; ISLANDS; ISOTOPES; MARSHALL ISLANDS; MICRONESIA; OCEANIA; RADIOISOTOPES; RESIDUES; SIZE Subject Categories: 500300* -- Environment, Atmospheric -- Radioactive Materials Monitoring & Transport -- (-1989) 450200 -- Military Technology, Weaponry, & National Defense -- Nuclear Explosions & Explosives (Item 589 from file: EDB-80-091258 103) ~ Title: Radioautographic studies of the materials obtained from the No. Fukuryu Maru contaminated by radioactive ashes Author(s): Kikuchi, T.; Akagi, H.; Goto, H.; Wakisaka, G.

Country of Origin: Japan Abstract: The contamination was associated with the presence of small radioactive particles. Although these particles were easily scattered, it was difficult to remove them completely. The particles did not penetrate into the interior of clothes of fine meshes. Decontamination by washing with sea water was not perfect.; Major Descriptors: *CLOTHING -- DECONTAMINATION; *FALLOUT -AUTORADIOGRAPHY Descriptors: ASHES; BIKINI; CONTAMINATION; NUCLEAR EXPLOSIONS; PARTICLES; I004018 10/5/889 00651733
