Thein, J. Bogard, K. Eckerman] An employee was contaminated with radioactive material consisting primarily of244Cm and246Cm as a consequence of handling a curium nitrate solution at a reprocessing facility.In vivo gamma analysis andin vitro (urine and fecal) analysis were initiated soon after the incident. Furtherin vivo measurements were performed regularly through hour 528, andin vitro bioassay measurements were obtained through day 74. A sample of the curium solution from the workplace was obtained to confirm that the nitrate was the chemical form in question and to identify the isotopes of curium present. The mass ratio of244Cm/246Cm was determined to be 91 to 7. Diethylenetriaminepentaacetate (DTPA) was administered on hours 33 and 71. Observed excretion rates were consistent with available information on curium. In this paper, the results of thein vivo andin vitro measurements are presented and intake estimates for the incident are developed using various excretion rate functions.
