摘　　要：本文采用静态和碎岩柱实验技术研究了放射性Sr和Cs在核废物处置库待选点花岗岩上的吸附与阻滞。结果表明:花岗岩对Sr的吸附为线性吸附,对Cs的吸附为非线性吸附。花岗岩对Cs的阻滞能力要比对Sr的阻滞能力好。The sorption and retardation of radioactive strontium and cesium on the granite from the candidate site for nuclear waste repository have been studied in this paper by means of batch and crushed rock column techniques. The results show that sorption of strontium on the granite is linear and sorption of cesium on the granite is non-linear. The retardation capacity of the granite to cesium is better than to strontium.
