摘要：

The segmented gamma ray scanning system developed for the assay of plutonium present in 200 L waste drums was modified for the estimation of gram amounts of plutonium in the presence of high beta gamma activity. A multi gamma ray source of Eu-152 having similar to 1 mCi activity was used for the determination of attenuation correction factors for high count rate drums. Dead time corrections were applied to arrive at the corrected count rates for all the gamma rays. Present study has shown that the estimation of similar to 1 g of Pu-239 in a waste drum can be carried out in the presence of Cs-137 up to an activity level of 20 mCi.
