| 摘 要： | 研究了采自新疆的风沙土对不同放射性核素的吸附与解吸情况。结果表明，风沙土对137Cs的吸附一解吸滞后作用明显，而对帅Sr的吸附一解吸滞后作用极微；风沙土对239Pu和238U的平衡吸附量分别为22．54cpm／mg和19．27cpm／mg，粒径为45μm的风沙土能牢固地吸附239Pu和238U。

| Abstract: | A study has been carried out on the adsorption and desorption of the different radionuclides by the aeoli- an sandy soil taken from Xinjiang Province. The results show that the hysteresis of adsorbing and desorbing 137Cs is obvious, while it is very slight for 90Sr. The equilibrium amount of 239Pu and 23SU adsorption is respectively 22.54 epm/mg and 19.27 epm/mg. The aeolian sandy soil with a particle diameter of 45 μm eould tightly hold 239pu and 238 U. |
