Abstract

A method for the separation and purification of environmental levels of plutonium and neptunium from totally digested sediment samples and determination of isotopic abundances of 237Np, 239Pu, 240Pu and 241Pu by ICP-MS has been developed. Data from the analysis of standard reference materials (SRM-4350B, IAEA-135, and IAEA-384), selected sediments collected from the Ob River, Siberia, and laboratory intercomparison analyses conducted with scientists at DOE's Environmental Measurements Laboratory using TIMS are presented and discussed. Chemical recoveries for Pu and Np are 90 and 70 percent, respectively. Measurement precision ranged between 1 and 5 percent for all isotopes except 241Pu, for which it was 10–15 percent. The lower limit of detection was 0.5 fg g−1 for all isotopes of interest.
