本文报道了深层页岩与含放射性 Cs、Sr 的地下水作用的研究结果和页岩对水泥混合浆液滤出水中核素的吸附试验结果。试验表明,在常压恒温下,不同深度页岩对地下水中 Sr 和 Cs 的分配系数K_d 值分别为34—52和1672—8993mL/g,对滤出水中放射性的吸附率为67—78%。用静态试验法研究核素迁移,可在较短的时间里获得结果,为放射性废物浅地层埋藏或地下处置的选址和环境安全评价提供参数。
This paper reports the results of the study on the interaction between deep shale and groundwater containing radioactive Cs and Sr, and the adsorption results of shale on the radionuclides in cement mixed slurries. The results showed that the K_d values of Sr and Cs in groundwater were 34-52 and 1672-8993 mL / g, respectively, at different temperatures and shales, and the adsorption rates of radioactivity to filtered water were 67-78%. Static tests can be used to study the migration of radionuclides and results can be obtained in a relatively short period of time, providing parameters for site selection and environmental safety assessment of shallow burial or underground disposal of radioactive waste.
