摘要
土壤中氡浓度检测是建筑工程勘察选址、地基设计中控制建筑物室内(尤其是低层)氡气的有效手段,我国规范中室内环境控制已被列为强制项目。通过实测北京市丰台区西南部、房山区东北部、海淀、大兴、石景山区等典型区域百余处工程的地质土壤,分析土壤中氡浓度检测数据,总结北京地区土壤中氡气分布的特点。
The test of radon concentration in soil is the effective means for building engineering survey location and indoor radon control in the design of building foundation (especially low-level) .Indoor environment control in the national standard is listed as mandatory items. In this article, through the measure of almost one hundred typical engineering geology in southwest of Beijing Fengtai district, the northeast of Fangshan district, Haidian district, Daxing district and Shijingshan district and the analysis of radon concentration test data, trying to summarize soil radon distribution characteristics in Beijing area.
