In July 1991 a plutonium worker at the Savannah River Site (SRS) was exposed to airborne plutonium-238 from a contaminated shipping container. She was chelated with Zn-DTPA shortly after the incident and placed on a special bioassay program. Based on early urinary and fecal excretion, an initial dose estimate of 1525 mrem committed effective dose equivalent (CEDE) was reported 20 days later. As additional bioassay data were collected the dose was revised to 1840 mrem CEDE on day 88 and to 3660 mrem CEDE on day 245. This last estimate was officially reported to the Department of Energy (DOE). The urinary excretion data and expectation curve for the model are shown. Only the data to the left of the first vertical line (3/92 Evaluation) were available at the time of the initial dose estimate.
