Assessment of internal exposure to the two acute exposure cases at waste management facilities have been carried out by whole body counting (in-vivo) and bio-assay (in-vitro) monitoring technique. These subjects were administered Ca-DTPA aerosol immediately after exposure. The initial whole body counting results showed internal contamination due to 137 Cs. Urinary excretion rate of 239 Pu and 241 Am in these cases are determined by means of standard radiochemical separation and estimation using 236 Pu and 243 Am tracers. The paper deals with the assessment of internal exposure to the radiation workers from waste management facility at Tarapur. It is observed that the assessed CED due to 137 Cs was very low while the actinides namely, 239 Pu and 241 Am, were the main contributors to the total CED. The CED for Case-I and Case-II was estimated as 8.54 mSv and 6.48 mSv respectively.
