/sup 238/PuO/sub 2/ contamination of the grit blasted surface of the primary impact shell assembly (PISA) of the multi-hundred watt isotopic heat source was measured. The study determined the amount and distribution of the /sup 238/PuO/sub 2/ and characterization of its behavior during aging at 1350/sup 0/C. The results concluded that normal decontamination effectively removes the superficial /sup 238/PuO/sub 2/ but does not extract the /sup 238/PuO/sub 2/ which is deep within the grit blasted structure. Subsequent heating results in migration of microcurie amounts of plutonium out of the grit blasted structure.
