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 +- 1.6 te 140.8 +- 6.8 counts/min/] were cbtained.
