PUQFUA: An IBM-704 FORTRAN code for determining plutonium body burden from urine assays.

239 PUQFUA i.san IBM-i’& FORTRAN program, written primarily for I% , which calculates from urinalyses the plutonium body burden in microcuries and the per cent of the maximum permissible body burden. It is based on a set of power function elimination equations developed by Wright H. Langham for the excretion of plutonium over a five year period. Results with PUQFUA compare favorably with those of other methods. In general, it is easy to apply for a large number of individual samples, and the validation method is objective and requires no past experience with plutonium body burden calculations on the part of the evaluator.
