Four employees at the Oak Ridge National Laboratory experienced an intake by inhalation of $sup 244$Cm as a result of an accidental release of this radionuclide. Urine and fecal samples were obtained and were analyzed in the Bioassay Laboratory at ORNL. Also, chest counts were made with the ORNL Whole- Body Counter. Ca-DTPA mists were inhaled within hours after the intake. These data together with data on the inhalation of $sup 244$Cm in the dog were used to obtain a 50-year dose commitment to lungs, skeleton, and liver. The 50-year dose commitment to skeleton for two of the employees was estimated to be about 170 rem. The estimation methods used for dose commitment together with the values for other organs obtained are presented and discussed. (auth)
