为了确定氡的易发区和评价氡的危险性，在深圳市进行了土壤气氡测量和γ能谱测量相结合的研究。同时，应用统计分析来评估测量结果的分布。本文介绍了氡风险评价的方法。根据土壤气氡浓度（RC）、土壤透气性（Perm.）铀（238U）浓度。结果表明，土壤气RC和氡易发区的分布与铀（238U）的地质分布和当地岩性密切相关。
In order to identify radon-prone areas and evaluate radon risk level, a soil gas radon survey combined with gamma-ray spectrometry measurements was carried out in Shenzhen City, south China. Meanwhile, the statistical analysis was applied to evaluate the distribution of measured results. This paper presents the methodology of the radon risk assessment. A radon risk map was accomplished based on a combination of soil gas radon concentration (RC), soil air permeability (Perm.) and uranium (238U) concentration. The results showed that the distribution of soil gas RC and radon-prone areas were closely related to geologic distribution of uranium (238U) and local lithology.
