Country of Origin: United States Abstract: An experiment was conducted at Kwajalein Atoll, Marshall Islands to investigate the spatial relationship of 1-m equatorial spread-F irregularities to total electron content (TEC) depletions. A high-power radar was operated (1) in a backscatter scan mode to spatially map the distribution of l-m irregularities, and (2) in a dual-frequency, satellite-track mode to obtain the longitudinal TEC variations. We show that radar backscatter ’’plumes’’ found in the disturbed, nighttime equatorial ionosphere are longitudinally coincident with TEC depletions. We suggest that the TEC depletions are probably due to the presence of plasma ‘'bubbles’’ in the equatorial F layer.; Major Descriptors: *SPREAD F -- IONOSPHERIC STORMS Descriptors: BACKSCATTERING; ELECTRON DENSITY; PLASMA INSTABILITY; RADAR Broader Terms: EARTH ATMOSPHERE; F REGION; INSTABILITY; IONOSPHERE; MEASURING INSTRUMENTS; PLANETARY IONOSPHERES; RANGE FINDERS; SCATTERING Subject Categories: 640201* -- Atmospheric Physics -- Auroral, Ionospheric, & Magetospheric Phenomena INIS Subject Categories: B33* -- Atmosphere 10/5/916 (Item 616 from file: 103) 00591064 AIX-10-482105; EDB-80-030587 Title: Fallout radiation and its impact on man Author(s): Lab.)

Coden: SCRPA Publication Date: Nov 1978 p 724-727 Document Type: Journal Article Language: English Journal Announcement: EDB7912 Subfile: AIX (non-US Atomindex input). Country of Origin: India Abstract: Fallout effects from nuclear explosions are discussed giving examples of the first atom bomb explosion of 1945 in Japan and H-bomb explosion on Bikini Island in Pacific in 1954. Fission and fusion processes which cause nuclear explosions are briefly explained. Genesis of radiation fallout and its types viz. (1) local or early fallout and (2) world-wide or delayed fallout are described. Local fallout being at very low altitude is more harmful as compared to world-wide or delayed fallout which may be either tropospheric or stratospheric. Hazards from radioisotopes such as /sup 131/I, /sup 90/Sr, /sup 89/Sr, /sup 137/Cs and /sup 14/C produced from nuclear fallout are described. Radiations cause a wide range of symptoms and syndromes characterized by ‘radiation sickness’. Somatic and genetic effects induced by “fallout radiations are explained.; Descriptors: MAN; *FALLOUT -- BIOLOGICAL RADIATION EFFECTS NUCLEAR EXPLOSIONS; RADIOISOTOPES Broader Terms: ANIMALS; BIOLOGICAL EFFECTS; PRIMATES; RADIATION EFFECTS; VERTEBRATES EXPLOSIONS; ISOTOPES; MAMMALS; Subject Categories: 560151* -- Radiation Effects on Animals -- Man INIS Subject Categories: C21* -- Tissue Distribution, Metabolism, Toxicology & Removal of Radionuclides 10/5/917 (Item 617 from file: 103) 00591038 INS-80-003540; ERA-05-012601; EDB-80-030561 Title: Marshall Islands: educational program Author(s): Naidu, J.R.
