ranging from 12 to 4600 nautical miles from Ground Zero. Several new kinds of instruments were constructed and used, and deep~sea instrument stations were installed on the tops of two mounts. The first water waves arriving at Eniwetok Island apparently traveled along paths outside the lagoon. At several of the stations there were two distinct arrivals of water waves, the first apparently being driven by. the propagated rise in atmospheric pressure caused by the explosion and thus traveling at the speed of sound and the second moving along the water surface in the usual manner at a velocity of the square root of gh. At the distant island stations a long-continued persistence of wave activity substantially above background was observed, modulated by sporadic enhancements that suggest reflections from major land masses. ; Major Descriptors: PROPAGATION Descriptors: *NUCLEAR EXPLOSIONS -- WATER WAVES; *WATER WAVES -- WAVE PACIFIC OCEAN; VELOCITY Broader Terms: EXPLOSIONS; SEAS; SURFACE WATERS Subject Categories: 450200* -- Military Technology, Defense -- Nuclear Explosions & Explosives 10/5/824 (Item 524 from file: 103) 00720498 EDB-81-028751 Title: Radioactivity in certain pelagic fish. confirmation of radioiron in skipjack Author(s): Amano, Subfile: TIC K.; Tozawa, H.; Takase, Source: Nippon Suisan Gakkaishi (Japan) Publication Date: 1956 p 1261-1268 Document Type: Journal Article Language: English Journal Announcement: EDB8103 (Technical A. v 21. IV. Weaponry, & National Separation and Coden: NSUGA Information Center). Country of Origin: Japan Abstract: Incinerated liver (0.2g.) and stomach (0.15g.) of a skipjack caught near the Bikini Atoll on June 19, 1954, were dissolved in 0.2N HCl, filtered, and the filtrates made up to 100 cc.; the radioactivities were 130 and 86 counts/min./cc., respectively. The solutions were passed through column of Dowex 50. Elution with 0.5% oxalic acid gave powerful radioactivity with liver, but very weak with stomach. Elution with a solution of NH/sub 4/ citrate at pH 3.5 from both samples showed strong radioactivity, probably due to the presence of /sup 65/Zn. Distinct radioactivity was also detected in the NH/sub 4/ citrate eluate at pH 4.1 from the liver, but not from the stomach; this eluted element emitted no ..gamma..-rays and differed from /sup 65/Zn. The elution behavior of the radioactive element in the 0.5% oxalic acid elution showed that it was Fe; elution by 0.6M HCl after adsorption to Dowex 1 supported this result. /sup 95/Zr and /sup 95/Nb were indicated from these data to be absent. The pulse height, distribution curve of ..gamma..-ray emitted by the element also coefficient of Al, Ag, and Au for x rays from /sup 55/Fe, /sup 63/Ni and the isolated element indicated that the element was /sup 55/Fe.; 2003 G8 | indicated that it was Fe. However, the radiation decay curve differed considerably from that of /sup 59/Fe, suggesting the presence of radioactive element with longer half-life.
