C231700100011 DETECTOR (NAICR,GEMUC) 3- x 3-in. NaI crystal. C231700100012 METHOD (CHSEP,ACTIV) After irradiation, the targets were C231700100013 dissolved in HCl; yttrium, strontium, and barium C231700100014 carriers were added and the solution was made C231700100015 strongly basic with NaOH to remove aluminum. After C231700100016 washing, the precipitate was dissolved in a small C231700100017 amount of concentrated HNO3, strontium and barium C231700100018 carriers were again added and then precipitated as C231700100019 nitrates with fuming nitric acid. The prepared C231700100020 samples were gamma counted as soon as possible flat C231700100021 against the aluminum shield of a NaI scintillation C231700100022 crystal. After a period of ten half-lives ( 32 h), C231700100023 the samples were beta counted with a lead shielded C231700100024 calibrated Geiger-Muller counter.
