| 内容記述 | Establishing accurate historical records of the distribution, inventory, and source of artificial radionuclides in the environment is important for environmental monitoring and radiological health protection due to their potential toxicity, and is also useful for identification and risk assessment of possible future environmental inputs of radionuclides from nuclear weapons tests and accidental release from the nuclear fuel reprocessing facilities or nuclear power reactors. We used a sector-field ICP-MS to study the recent sedimentation of Pu isotopes in 11 lakes in China. The distribution of 137Cs was investigated using the conventional radiometric analytical methods. Based on the isotopic compositions of Pu and the activity ratio of 137Cs/239+240Pu, the sources of artificial radionuclides were identified. The potential applications of Pu isotopes for sediment dating and for regional and global environmental change studies were discussed. | |||||
