| Abstract: | ~(239)Pu is one of the most poisonous nuclides. Systematic research on ~(239)Pu levels and its distribution in the water environment, especially, in the river environment, was not reported in china so far. Based on the determination of ~(239)Pu in the upper reaches of Changjiang River and the river system in Sichuan, the distribution and its pattern of ~(239)Pu are reported in thispaper. Major sources of ~(239)Pu in the water of the Changjiang River are discussed, and a deposition pattern in the underwater deposit of the reach from yibin to yichang is presented. |
