AN-Pu-R  Rapid Analysis of Plutonium in Environmental Samples (No.28)

If an accident occurs at a nuclear fuel reprocessing plant, α-emitting nuclides such as plutonium are expected to be released to the environment, and indexes for plutonium and transuranium elements are newly added to the indexes related to the restrictions on food and drink intake provided in the Disaster Prevention Measures for Nuclear Facilities, Etc. (Nuclear Safety Commission, November 1998). In such an emergency situation, an analysis method that has a much lower limit of detection than the indexes and is able to obtain results rapidly for long half-life nuclides such as plutonium will be required. For this manual, we established an analysis method that allows for carrying out pretreatment, chemical separation, measurement, calculation, and reporting within about 24 hours by adopting ICP-MS as the measurement equipment and speeding up the process from pretreatment through separation and refinement.
