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 indicated that it was Fe. However, the radiation decay curve differed considerably from that of /sup 59/Fe, suggesting the presence of radioactive element
