摘要

///Through static state attracts experiment, the adsorption properties of the wall rocks for Uranium, Strontium, Cesium were studied, and then the safety coefficients of the landfill sites and the necessity of establishing corresponding geochemistry barberries were assessed. The results show that the natural barrier made up of the wall rocks in site zone and buffer zone was safe to Cesium, but unsafe to Uranium and Strontium. It was necessary that the geochemical engineering barriers of Uranium and Strontium should be set up in site zone. The charges of soils and ionic radius of Sr²⁺, Cs⁺ significantly affect the adsorption properties of the wall rocks for Uranium, Strontium.
