PLUTONIUM EXCRETION DATA FROM THE 1945 - 1947 HUMAN INJECTION STUDY -CORRECTION FOR RECOVERY LOSSES AND DERIVATION OF RATE-CONSTANT FOR LONG-TERM ELIMINATION

Information on the short-term plutonium urinary excretion data obtaine d from the 1945-1947 human injection study is examined and it is shown that chemical recovery corrections need to be made. Revised and exten ded data sets, excluding those data considered to be atypical of perso ns in normal health, are presented. On the basis of the observed data for two injection study cases, with late estimates of excretion rates, a rate constant for the long-term elimination of plutonium from the b ody of 4.24 x 10(-5) d-1 is derived.
