Cua's Research Proposal: a) pb) Cc} ‘he effect of the dental program on the retention of Sr and Pu in these teeth samples can be studied. 90sr, 24lam (if present) activity concentration and 99sr autoradiograph can be obtained from the M.I. samples analyzed for Pu. Sr teeth results can be compared to corresponding 9°Sr bioassay result (if urine samples are obtained from people whose teeth are extracted). Unlike 239pu, 90Sr are easily detected in the M.I. urine samples qd) report by BF. LT. Cua to Tommy McCraw) .
