Assessment of internal contamination of lung/skeleton/liver is required on a routine basis for occupational workers in fuel fabrication and reprocessing plants handling actinides. Assessment of lung/organ burden of actinides is carried out inside the totally shielded steel room whole body counter using Phoswich and array of HPGe detector. This paper describes studies carried out for calibration of the two detection systems for 241 Am source embedded at different depths in tissue equivalent perspex slabs. The calibration factors thus derived will be helpful in the estimation of embedded activity in the tissues of the radiation workers in cases of internal contamination due to wound in the workers handling actinides.
