Uranium in man based on urinary excretion data

Generalized models for making prompt and final evaluations of uranium uptakes and resulting dose commitments to lung and bone using urinary excretion data are presented. Pathways and clearance times developed by researchers and accepted by health physicists are described for Class D, W, and Y compounds of uranium. This includes exponential clearance from the lung to blood and clearance from bone described by a power function equation. Although this paper deals with evaluations using urinary excretion data solely, this practice is not recommended since a better evaluation can be made by combining urinary excretion and in vivo examination data
