DIFFUSION BEHAVIOR OF SOME WEAKLY ABSORBED NUCLIDE SPECIES IN GRANITE

摘要

摘要: 采用实验室模拟方法研究了99TcO-4和HTO在某花岗岩中的扩散行为,获得了扩散系数。并对99TcO-4,HTO以及文献中报道的一些弱吸附性放射性物种在花岗岩中的扩散系数与分子量的关系进行了初步分析。分析表明,在花岗岩中,99TcO-4,HTO,125I-,36Cl-等弱吸附性放射性物种的扩散系数与相应物种的分子量的平方根近似成反比关系。

Abstract: The diffusion behavior of))~99)TcO~-4 and HTO in granite slice samples is investigated by laboratory simulation method. The apparent diffusion coefficients of))~99)TcO~-4 and HTO in the granite are obtained. In comparison, the relation of the apparent diffusion coefficients of))~99)TcO~-4 and HTO in the granite and the diffusion coefficients of some other nuclide species in granites reported by other scientists to the inverse ratio of the square root of their molecular mass is analyzed. The analysis indicates that for the main species of some wealky absorbed nuclide species, such as))~99)TcO~-4,HTO,~125)I~-,~36) Cl~- et al., the ratio of the apparent diffusion coefficient seems to be inversely related to the ratio of the square root of the molecular mass.
