Summary
The elemental composition of 111 plutonium-bearing particles was determined (using an electron microprobe) as part of a program to investigate the origin and behavior of the long-lived transuranic radionuclides released from fuel reprocessing facilities at the Savannah River Plant. These particles, collected from wet-cabinet and room-air exhausts from the plutonium finishing operation (JB-Line), were between 0.4 and 36 ..mu..m in diameter. Ninety-nine of the particles were found to be aggregates of various minerals and metals, six were quartz, and six were small (less than 2-..mu..m-diameter) pieces of iron oxide. Collectively, these particles contained less minerals and more metals than natural dusts contain. The metallic constituents included elements normally not found in dusts, e.g., chromium, nickel, copper, and zinc. Concentrations of aluminum and iron exceeded those normally found in minerals. Elemental concentrations in individual particles covered a wide range: one 2-..mu..m-diameter particle contained 97 percent NiO, a 9-..mu..m-diameter particle contained 72 percent Cr/sub 2/O/sub 3/. Although the particles were selected because they produced plutonium fission tracks, the plutonium concentration was too low to be estimated by microprobe analysis in all but a 1-..mu..m-diameter particle. This plutonium-bearing particle contained 73 percent PuO/sub 2/ by weight in combination with Fe/sub 2/O/sub 3/ and mica; its activity was estimated at 0.17 pCi of /sup 239/Pu.
