The activity concentrations of 238U, 232Th and 40K were found using high-resolution gamma-ray spectrometry on depth profile samples collected from the Kalaburagi districts. This study aims to ascertain the radioactivity Changes concerning the depth profile. With values of 51.64 ± 0.50 Bq kg-1 for 238U, 58.77 ± 0.23 for 232Th and 313.92 ± 3.57 for 40K, respectively, the depth profile samples of Jayanagar in the Kalaburagi region exhibit significant activity concentrations among the measured values. Moreover, estimates of the K/Th and K/U ratios have been made, based on surface-level collected samples, which may have values that differ from the samples under study.
在卡拉巴格地区采集的深度剖面样本上，使用高分辨率伽马能谱法发现了 238U、232Th 和 40K 的活度浓度。本研究旨在确定放射性随深度剖面的变化。在卡拉巴格地区 Jayanagar 的深度剖面样本中，238U 的活度浓度分别为 51.64±0.50 Bq·kg-1，232Th 为 58.77±0.23，40K 为 313.92±3.57，其活度浓度值在测量值中属于较高水平。此外，还根据表层采集的样本估算了 K/Th 和 K/U 比值，这些比值可能与研究中的样本有所不同。
