内容記述 | In order to obtain precise Pu isotope composition of Irish Sea water reference material issued by the International Atomic Energy Agency (IAEA-381), we analyzed the activities of 239Pu, 240Pu and the atom ratio of 240Pu/239Pu by a highly sensitive isotope dilution SF-ICP-MS method combined with two-stage chromatographic separation and purification. With a mean chemical yield of 65 % for 242Pu tracer, the experimentally established values for 239Pu, 240Pu and 239+240Pu activities are in good agreement with the certified ones. For the 240Pu/239Pu atom ratio, we obtain a value of 0.2315  0.0008 with a high precision (RSD, 0.35 %), which is much more precise than the information value of 0.22  0.03 (RSD, 13.6 %) provided by the IAEA certification report. It is our conviction that the precise determination of Pu isotopes in this seawater reference material will be useful for the validation of analytical method for the study of radionuclides in the marine environment. | |||||
