Description/Abstract:
ANALYSES OF TISSUE ALIQUOTS FROM A PLUTONIUM PROCESS OPERATOR, WHO HAD BEEN EXPOSED TO PU-239 LARGELY VIA CHRONIC LOW-LEVEL INHALATION FOR APPROXIMATELY 6 OUT OF 11 AND ONE HALF YEARS OF EMPLOYMENT, SHOWED THAT HE HAD ACCUMULATED A BODY BURDEN OF APPROXIMATELY 0.018 UC. ESTIMATIONS OF HIS BODY BURDEN FROM HIS URINE ASSAY RECORD RANGED FROM 0.019 TO 0.034 UC. THE HIGHEST PLUTONIUM CONCENTRATION (125 DIS/MIN PER G) WAS FOUND IN PULMONARY LYMPH NODES, FOLLOWED BY LIVER (9.9 DIS/MIN PER G), LUNGS (4.8 DIS/MIN PER G) AND BONE (AVERAGE OF STERNUM, RIB AND VERTEBRA, 1.4 DIS/MIN PER G). SOME IMPLICATIONS OF THESE FINDINGS TO CHRONIC LOW-LEVEL INHALATION EXPOSURES AND TO ESTIMATION OF BODY BURDEN FROM URINE ASSAYS ARE DISCUSSED.
