The results of monitoring the radon volumetric activity (RVA) in soil air at eight testing sites located in the fault zones and beyond them are presented. The dependence of the changes in radon volumetric activity on the depth of the well, time of day, and meteorological parameters, main of which being temperature, is revealed. Based on the entire set of the collected data, the optimal conditions for conducting the profile radon surveys aimed at identifying the fault zones in platform conditions are determined.

台地区域氡体积活度测量技术

介绍了在位于断层带及其以外的八个测试点监测土壤空气中氡体积活度 (RVA) 的结果。揭示了氡体积活动变化对井深、一天中的时间和气象参数（主要是温度）的依赖性。根据收集到的整套数据，确定进行旨在识别平台条件下断层带的剖面氡调查的最佳条件。
