Abstract: Sea water collected around the Bikini Atoll from July to
September 1954, was analyzed for total radioactivity by adding 2 g
solid NH/sub 4/Cl,
g/l),
1 ml of an aqueous solution of Ferric alum (86.3
and 1 ml of BaCl/sub 2/ solution
(17.8 g/l)
to 1 1 of H/sub 2/0
heated to 60 to 70 while being stirred. NH/sub 4/0H was added until the
solution was faintly pink to phenolphthalein. After 2-min boiling the
precipitate settled on standing for several hours at room temperature
before being filtered on a filter disk lain above a glass filter.
Counting rates of 2.1 +- 1.6 to 140.8 +- 6.8 counts/min/1 were
obtained.;

Abstract: Following a fallout estimated at 0.2 microcurie/1l, Trifolium
repens, Astragalus sinicus, and Rumex japonicus were harvested and
analyzed for radioactivity. Most of the radioactivity (2300 to 4700
counts/min/50 g plant ash) was associated with oxalate precipitate. A
small amount of activity in the Zn group is attributed to /sup 65/Zn
produced by reaction /sup 64/Zn (n,..gamma..) from Zn employed in the
mechanical parts of the bomb. Sr-Ba radioactivity was 0.1 that of the
rare earth group. Distribution of the radioactive elements was nearly
the same as that found on the No. 5 Fukuryu-Maru.;
