放射性固体废物的处置已成为世界各国密切关心,也是亟待解决的一个问题。1980年美国Erdal等就粘土对裂变产物Ce,Sr,Ba,Eu,U,Am等核素的吸附情况进行了研究。1985年瑞典Torstenfel等对Sr,Tc,I,Ce,Th,U,Np,Pu,Am等核素在粘土中的迁移、扩散情况作了探讨。英国、芬兰、瑞典均对混凝土对多种核素的吸附和扩散作用进行过研究。白庆中等和庄慧娥等对放射性核素Sr,Cs在地质介质中的吸附和迁移规律也进行了研究。
The disposal of radioactive solid waste has become a matter of close concern among all countries in the world and is also an issue to be solved urgently. In 1980, Erdal et al. Studied the adsorption of fission products Ce, Sr, Ba, Eu, U, Am and other nuclides by clay. In 1985, Torstenfel in Sweden discussed the migration and diffusion of Sr, Tc, I, Ce, Th, U, Np, Pu and Am in clay. Britain, Finland and Sweden have studied the adsorption and diffusion of concrete to various radionuclides. Bai Qingzhong and Zhuang Huai E and other radionuclides Sr, Cs adsorption in the geological medium and the law also conducted a study.
