Determination of plutonium activity levels and 240Pu/239Pu isotope ratios in bone collected from nonoccupationally-exposed individuals living in Colorado

Description

Los Alamos scientists measured 239+240Pu alpha activities and 240Pu/239Pu atom ratios in bone tissues collected from Colorado residents who were not occupationally exposed to this type of radioactivity. Bone tissues from 519 individuals were collected from 1975 to 1979 as part of an Environmental Protection Agency directed project to determine the effect of plutonium on people who live in areas surrounding the Rocky Flats Plant. Los Alamos selected 59 individuals who were suspected of having high plutonium body burdens based on the plutonium content of their livers. The plutonium activity level in the subset of bones analyzed in this study contained 7.8 ± 9.4 pCi 239+240Pu/10 kg wet weight. The average 240Pu/239Pu atom ratio was 0.182 ± 0.068; this ratio suggests that the plutonium detected in these individuals originated predominantly from global fallout
