Radionuclide activity of the selected radionuclides 238U, 232Th and 40K was measured in surface soil samples collected from 40 villages of the western part of Yadgir district of Karnataka. A 4″ × 4″ NaI (Tl) detector based on a gamma spectrometer is used for the estimation of radionuclides. The major type of soil in this region is sandy and red. The 222Rn activity concentrations in drinking water were determined by the Emanometry method. The 222Rn activity in ground water is found to vary from 1.73 to 155.6 Bql-1. The total annual effective doses because of 222Rn inhalation and ingestion range from 4.72 to 424.84 μSv y-1 with an average value of 108.8 μSv y-1, respectively. Among the sampling stations, Shahapur and Shorapur soil samples show higher activity values than the Kembhavi and Hunasagi sampling stations soil samples.
在卡纳塔克邦亚德吉尔区西部的 40 个村庄采集了表层土壤样本，测量了所选放射性核素 238U、232Th 和 40K 的放射性核素活度。使用基于伽马谱仪的 4"×4" NaI(Tl)探测器来估算放射性核素。该地区的主要土壤类型为沙质和红色。通过压氡计法测定饮用水中的 222Rn 活度浓度。发现地下水的 222Rn 活度从 1.73 到 155.6 Bq l-1 不等。由于 222Rn 的吸入和摄入，每年的总有效剂量从 4.72 到 424.84 μSv y-1 不等，平均值为 108.8 μSv y-1。在采样站中，Shahapur 和 Shorapur 的土壤样本的活度值高于 Kembhavi 和 Hunasagi 采样站的土壤样本。
