摘要
研制了花岗岩单裂隙扩散实验装置 ,用12 5 I、134Cs进行了核素扩散实验 ,求得扩散系数并测定了裂隙表面的放射性活度分布。
An experimental installation simulating nuclide diffusion in granite with single fracture is developed. The experiment of 125 I -, 134 Cs + diffusion in granite rock with single fracture is made. Based on given conditions, the diffusion coefficient and radioactive strength distribution on nuclide adsorption by its surface are obtained.
