Surface soil samples were collected from Konya, Turkey and natural activity concentrations were determined using the ɤ-ray spectroscopy system with HPGe detector. The activity concentrations of Ra, Th and K were found to vary from 14.07 ± 0.71 Bq kg dw to 67.27 ± 1.62 Bq kg dw, 10.19 ± 2.60 Bq kg dw to 46.09 ± 0.76 Bq kg dw and 107.87 ± 13.32 Bq kg dw to 605.95 ± 11.34 Bq kg dry weight (dw), respectively. The radiological hazard parameters such as Ra, D, AEDE, ELCR, AGDE, H, H, and Iɤ evaluated the radiological risk for the public and environment. The mean values of D, AEDE and ELCR are lower than the world average value of 57 nGy h, 70 μSv y, 0.29 × 10 respectively. The activity concentration distribution maps of Ra, Th and K and the radiological maps of the radiological hazard parameters were plotted using the Surfer programme. Cluster analysis was carried out to indicate the similarity between the variables.
从土耳其科尼亚采集了表层土壤样本，并使用带有 HPGe 探测器的γ射线能谱系统测定了其自然放射性活度浓度。结果表明，镭、钍和钾的活度浓度分别在 14.07±0.71 Bq kg dw 至 67.27±1.62 Bq kg dw、10.19±2.60 Bq kg dw 至 46.09±0.76 Bq kg dw 和 107.87±13.32 Bq kg dw 至 605.95±11.34 Bq kg dw 之间变化。通过评估镭、剂量率、有效剂量当量、平均有效剂量当量、公众有效剂量当量、个人有效剂量当量、公众年有效剂量当量、公众年有效剂量和内照射指数等辐射危害参数，评估了这些地区的公众和环境所面临的辐射风险。这些参数的平均值均低于世界平均值，其中剂量率、有效剂量当量和公众年有效剂量当量分别为 57 nGy h、70 μSv y 和 0.29×10。利用 Surfer 程序绘制了镭、钍和钾的活度浓度分布图以及辐射危害参数的辐射图。并通过聚类分析来表示变量之间的相似性。
