Werk Location: Japan Abstract: Incinerated liver (0.29.) amd stomach (0.159.) of a skipjack caught near the dikini Atell on June 19, 1954, were dissclved in ©.2@N HCl, filtered, and the filtrates made up te 16090 cc.: the radicactivities were 130 ard 8&6 counts/min./ce., respectively. The solutions were passed through column of Dowex 50. Elution with 0.5% oxalic acid gave powerful radicactivity with liver, but very weak with stomach. Elution with a sclutiaon of NH/sut 4/ citrate at pH 3.5 from both samples showed strong radicactivity, probably due ta the presence caf /sup 65/2n. Distinct radioactivity was alse detected in the NH/sub 4/ citrate eluate at pH 4.1 frem the liver, but not from the stomach: this eluted element emitted na radioactive element in the 0.5% axalic acid eluticn shawed that it was Fe; Elution by O.5M HC] after adscrptian te Dowex 1 supported this result. /sup GS/i° and /sup S8/Nk were indicated from these deta ta be absent. The pulse neiart dietriadution curve cf ..gamma,.-ray emitted by the eienent elsa indicated that it was Fe. Hawever, the vad:eticen decay curve differed considerably from that cf /sup 87/Fe, sucgesetirg the presence af vadicective element with longer half-life. Conperisan af the absorption coefficient af Al, Ag. and Au fer « raye from /suop F5/Fe, /sua 63/Ni ard the iscleted elenent indicated that the elemert was /sup SE/Fe. “CTfFL06 SCile 194: > VECE9T ALX-12:881469., EDB-81:928555 Title: Dietary enctivity intake fram pecaseay data: a model acplied to /s.ap 137/Cs intake by Ei kind Tsiand resident Rarthoacs ‘essard, E.T.3 Miltenberger, F.F.: Ereenhcuce, Hoa.

Work Location: United States Abstract: This paper presents an equation with which the censtant daily activity ingestion rate may be calculated from sequentially obtained whole bedy counting and urine bicassay data. The medel was developed tc relate whole bedy ceunting results to urinary activity excretion data for /sup 137/Cs in the Marshallese population at Bikini Island for whom accurate dietary intake and residence interval information were net available. The technique is anpliceble to radioactive material whese biclagical and physical ranoval mechanisms are linear first order processes described by appropriate rate constants which give the instantanecus fraction of atcame transterrad from compartments in the body ta urine per unit time, and the ingcantanecus fraction of etoms decaying per unit time.
