Abstract

The speciation of ^{238, 239, 240}Pu in the bottom sediments of two reservoirs of PA Mayak are investigated. The maximum content of plutonium in reservoir R-17 is found in the residual fraction. In reservoir R-4, plutonium is distributed equally in the residual fraction and the fraction bound to organic matter. The fact that plutonium exists in physico-chemically immobile fractions indicate its low biological availability.

抽象

的形态^{238，239，240}浦PA马亚克的两座水库底部的沉积物进行了研究。在残余馏分中发现储层R-17中p的最大含量。在储层R-4中，p在剩余馏分和与有机物结合的馏分中平均分布。在物理化学上不可移动的部分中存在的事实表明其生物利用度较低。
