| Abstract: | An analytical method for the determination of 239Pu and 240Pu in marine particle samples by sector field high-resolution ICP-MS was developed. The method was applied for large and small
particle samples (particle diameter: >70 μm and 1–70 μm, respectively, collected with a large volume in situ filtration and
concentration system at different depths in the water column off Rokkaho, Japan, where the spent nuclear fuel reprocessing
plant of Japan Nuclear Fuel Ltd. has started test operation since March 2006. |
