氡的地质潜势是环境氡研究的重要内容，也是从地质背景出发快速评价氡浓度水平的有效方法。氡析出率是反映氡地质潜势的最好参数。根据放射性元素分布规律、地质背景及放射性元素衰变等，建立了计算氡析出率的理论公式。理论计算结果表明，北京市区氡的地质潜势分为四个不同的区，不同潜势区中室内氡浓度水平发生相应变化。说明通过氡地质潜势规律研究，可以确定室内氡浓度水平潜在高值区。
The geological potential of radon is an important part of environmental radon research and an effective method for rapid assessment of radon concentration level from the geological background. Radon rate is the best reflection of radon geology potential parameters. According to the rules of radioactive element distribution, the geological background and the decay of radioactive elements, a theoretical formula for calculating the radon exhalation rate has been established. The theoretical calculation results show that the geological potential of radon in Beijing is divided into four different zones, and the indoor radon concentration levels in different potential zones change accordingly. This shows that by studying the law of radon geologic potential, the potentially high value of indoor radon concentration level can be determined.
