Chest and systemic burdens were estimated for two employees who inhaled largely soluble compounds of $sup 244$Cm. Chest burdens by whole-body counting were: Case A, 28 nCi; Case B, 34 nCi. The urinary excretion of the employees appeared to conform to a series of exponentials similar to those reported for blood and whole-body retention of Am in baboons. Accordingly, retention functions composed of a series of exponentials having 4, 12 to 17, and 72 day half-times were derived from urinary excretion and used to calculate body burdens, Case A, 7 nCi and Case B, 16 nCi. Cumulative fecal excretion by Case B was some 20 times that by Case A (63 nCi vs. 3.2) probably due to differences in deposition in the respiratory tract. Calculated organ doses for the first year were approximately 20 percent of recommended maxima. (auth)
