The study shows how geology and tectonic activity affect the soil gas Rn concentration. The tectonically active zone, namely the Ghuttu region, which is located within the Himalayan seismic belt, was studied to decipher its impact on soil gas Rn concentrations. A soil gas Rn study was performed in the soil at a depth of 30 cm, and it varied from 426 ± 156 Bq m to 24,057 ± 1110 Bq m with an average of 5356.5 ± 1634.6 Bq m and at 60 cm below the soil surface, the concentration varied from 1130 ± 416 Bq m to 30,236 ± 1350 Bq m with an average of 8928.5 ± 2039.5 Bq m. These concentrations vary in soil from −3.4 % to 437.3 % as the depth moves from 30 cm to 60 cm. The variation in uranium content also shows anomalies, and higher values of uranium content in the soil affect the radon concentration in the study area. The average soil gas Rn concentration in the Ghuttu window was found to be higher than that in its surrounding region. This is likely due to transportation from daughter products of uranium. Rn mass exhalation rate measurements were also carried out, and a weak correlation with the soil gas Rn concentration was observed. A significant variation in the mass exhalation rate was noticed in tectonically active areas. This study is vital to understanding the behavior of radon and uranium in tectonic regions.

印度喜马拉雅构造活动带氡输运和铀含量评估

该研究揭示了地质和构造活动如何影响土壤气体 Rn 浓度。研究人员对位于喜马拉雅地震带内的构造活动区（即古图地区）进行了研究，以解读其对土壤气体 Rn 浓度的影响。土壤气体 Rn 研究在 30 cm 深度的土壤中进行，其变化范围为 426 ± 156 Bq m 至 24,057 ± 1110 Bq m，平均为 5356.5 ± 1634.6 Bq m，在土壤表面以下 60 cm 处，浓度范围为 1130 ± 416 Bq m 至 30,236 ± 1350 Bq m，平均值为 8928.5 ± 2039.5 Bq m。随着深度从 30 厘米移动到 60 厘米，土壤中这些浓度从 -3.4% 变化到 437.3%。铀含量的变化也表现出异常，土壤中铀含量的较高值会影响研究区域的氡浓度。古图窗内的平均土壤气体 Rn 浓度高于其周围区域。这可能是由于铀子产品的运输造成的。还进行了 Rn 质量呼气速率测量，观察到与土壤气体 Rn 浓度的弱相关性。在构造活动区域注意到质量呼气率的显着变化。这项研究对于了解构造区域中氡和铀的行为至关重要。
