Saptember 1954, wes analyzed for total radicactivity by adding 2 g selid

NH/eub 4/Ci, 1 ml of ar aquecus selution of Ferric alum (86.9 9/1), and 1
ml of BaCl/sub @/ solution (17.8 g/l) te 1 1 of H/sub 2/0 heated te 40 ta
70 while being stirred. NH/sub 4/0H was added until the solution was
faintly, pink ta phenolphthalein. After e-min boiling the precipitats
settied cr standing fer several hours at reom temperature before being

filterad on a filter disk lain above a glass filter. Counting rates cf 2.1

Agetract: Follewing a fallout estimated at 9.2 macroecurie/’], Trifclium
recrens, Setrecalus einicus. and Rusme-~ jJagsanicus were harvestec and anelyzed

for racicactivity. Most oF the rediosactivity (2305 te 4700 counte/min/S9 ¢
clant a&h} was asseciated with analate precipitate. A emall ameunt of
activity in the Zn ereup is attributed te /sup S2/in preduced by reaction
/2up &$’on (m,..géerma..) from cn emolaved in the merhanical parts cf the

bomb. Sr-Ha radicactivity wes 0.1 that cf tre rare earth group.

Distribution cf the radisactive elements was early the same as thet found
