Description/Abstract:
DATA FROM HUMAN CASES OF PLUTONIUM INHALATION ARE USED TO ILLUSTRATE S EVERAL IMPORTANT PROBLEMS IN THE CURRENT METHODS OF ESTIMATING PLUTONI UM BODY BURDENS. INDIVIDUALS EXPOSED TO PLUTONIUM 238 OXIDE PARTICLES IN A HIGHLY INSOLUABLE MATRIX SHOWED AN UNUSUALLY SLOW RISING URINARY EXCRETION CURVE OVER 300-400 DAYS. IN VIVO CHEST COUNTS DURING THE FIR ST MONTHS ESTIMATED LUNG BURDENS TO BE 10-30 NANOCURIES BUT URINARY EX CRETION METHODS CALCULATE CRETION METHODS CALCULATE RESIDUAL SYSTEMIC BODY BURDENS OF 50 TO 100 NANOCURIES AT 1200 DAYS AFTER EXPOSURE. CURRENT ASSUMPTIONS USED IN TH E IN VIVO CALIBRATION DO NOT CONSIDER POSSIBLE LUNG DISTRIBUTION OF PA CRETION METHODS CALCULATE RESIDUAL SYSTEMIC BODY BURDENS OF 50 TO 100 NANOCURIES AT 1200 DAYS AFTER EXPOSURE. CURRENT ASSUMPTIONS USED IN TH E IN VIVO CALIBRATION DO NOT CONSIDER POSSIBLE LUNG DISTRIBUTION OF PA RTICULATES SOON AFTER EXPOSURE THAT COULD ALTER THE INTERPRETATION SIG NIFICANTLY.
