| 摘 要： | 本文叙述了放射性核素~(137)Cs、~(90)Sr-~(90)Y和~(144)Ce-~(144)Pr在地下水和岩石间的分配系数K_d的实验室测定方法,研究了放射性核素浓度、岩石种类及岩石粒度对K_d值的影响。测定了这三种核素模拟在三万吨TNT地下核爆炸空腔充满水时的浓度下的分配系数K_d值,计算了它们在地下水中的迁移速率。

| Abstract: | Th laboratory determination method was presented of distri-bution co ffici nts (K_d) between underground water and rock for radion-uclidos of~(137) Cs, ~(90)Sr-~(90)Y and ~(144)C- ~(144)Pr in this paper.The effects ofradionuclide concentration, rock type and its size .on K_d was also studiedThe values were d t rminded of three kinds of nuclides under the concen-tration simulating that when the hollow cavity formed by underground explosion at 30000 ton grade was full,of Water Their migration velocitiesin underground water were calculated. |
