摘要
Abstract
Clay is an excellent material in reducing radon emissions and health risks from uranium tailings.The compactness and moisture content of clay covered on uranium tailings can be altered on site.The effectiveness of earthen thickness for Radon attenuation depends on the compactness and moisture content of clay.When the moisture content of clay is greater than the " classic moisture content",the moisture content will decrease instead with the increase of compactness.The relations between radon attenuation efficiency,compactness,moisture content and thickness of clay are nonlinear.By analyzing these relations,geotechnical parameters are optimized to achieve an optimal effect on clay covering.关键词
