In this study, the levels of the natural and artificial radioactivity in soil samples collected from surrounding of Karaman in Turkey were measured. Activity concentrations of the concerned radionuclides were determined by gamma-ray spectrometry using a high-purity germanium detector with a relative efficiency of 40 % at 1.332 MeV. The results obtained for the (238)U series ((226)Ra, (214)Pb and (214)Bi), (232)Th series ((228)Ac), (40)K and fission product (137)Cs are discussed. To evaluate the radiological hazard of radioactivity in samples, the radium equivalent activity (Raeq), the absorbed dose rate (D), the annual effective dose and the external (Hex) and internal hazard index (Hin) were calculated and presented in comparison with the data collected from different areas in the world and Turkey.
在本研究中，对从土耳其卡拉曼周边采集的土壤样本中的天然和人工放射性水平进行了测量。使用相对效率在1.332 MeV时为40%的高纯锗探测器，通过伽马射线能谱法测定了相关放射性核素的活度浓度。讨论了针对（238）U系列（（226）Ra、（214）Pb和（214）Bi）、（232）Th系列（（228）Ac）、（40）K和裂变产物（137）Cs所获得的结果。为评估样本中放射性的辐射危害，计算了镭当量活度（Raeq）、吸收剂量率（D）、年有效剂量以及外照射（Hex）和内照射危害指数（Hin），并与从世界不同地区和土耳其收集的数据进行了比较。
