摘要
^(239)Pu是一种极毒的放射性核素,水环境,尤其是江河环境中^(239)Pu的水平与分析情况,目前在国内还未见有系统的报道,本文通过对长江的一些江段及川江水系水环境中^(239)Pu水平的分析,探讨了其分布情况及规律;并初步分析了目前长江水域中^(239)Pu的主要来源;得出了研究江段水底沉积物中^(239)Pu的沉积规律。
^(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.
