 note = {So far, there is no established mass spectrometric method for simultaneous determination of these hard-to-measure 238Pu, 239Pu, 240Pu and 241Pu in environmental mediums. In this study, we developed an advanced mass spectrometry method for simultaneous analysis of important Pu isotopes (238,239,240,241Pu) using triple quadrupole ICP-MS/MS by employing the ion-molecule reaction separate 238U and 238Pu, which was previously difficult to be measured. By introducing a desolvation sample introduction system, we succeeded in increasing 10 times the sensitivity of Pu isotopes and suppressing the production of uranium hydride, we achieved the detection limit of fg level in on-mass mode. We have developed a new low-temperature fusion method for environmental and nuclear decommissioning samples. By combining these new sample preparation techniques with the developed ICP-MS/MS detection, rapid Pu isotope mass spectrometry methods for environmental samples and decommissioning related waste samples were established., 日本放射化学会第64回討論会(2020)},
