This study reports the exhalation rates of radon and thoron from surface soil collected from 60 rural sites of district Hisar, Haryana, India. The exhalation rates of Rn (radon) and Rn (thoron) were measured by portable SMART RnDuo (AQTEK SYSTEMS) using a mass accumulation chamber which was equipped with a scintillation material-coated cell. Dose rates due to natural gamma radiations ranged from 0.526 to 1.139 mSv y. The Rn mass exhalation rate in soil samples varied from 0.14 to 94.65 mBq kg h. Thoron surface exhalation rates ranged from 46.42 to 619.88 Bq m h. This study gives an idea about the differences in Rn and Rn exhalation at different locations which may be due to variations in geological features of the locations and characteristics of the topsoil. The findings show that usage of study area soil as building material is safe.
本研究报告了从印度哈里亚纳邦希萨尔区 60 个农村地区采集的表层土壤中氡和钍的排放率。使用配备闪烁材料涂层室的质量累积室，通过便携式 SMART RnDuo（AQTEK SYSTEMS）测量了 Rn（氡）和 Rn（钍）的排放率。由于天然伽马辐射引起的剂量率范围为 0.526 至 1.139 mSv y。土壤样品中的 Rn 质量排放率从 0.14 到 94.65 mBq kg h 不等。钍的表面排放率范围从 46.42 到 619.88 Bq m h。本研究提供了关于不同地点 Rn 和 Rn 排放差异的信息，这可能是由于地点的地质特征和表土特征的变化。研究结果表明，使用研究区域的土壤作为建筑材料是安全的。
