The concentrations and distribution of natural and anthropogenic radionuclides in soils from around the Kestanbol (Canakkale), Turkey were investigated with an aim of evaluating the environmental radioactivity and radiological health hazard. Concentrations of radionuclides in the samples were determined by gamma ray spectrometer using HPGe detector. In the soils in general, the concentration of (232)Th was found to be higher than that of the (238)U and the activities of (232)Th and (238)U in this area are higher than the world average. (137)Cs was observed in all the samples, ranging from 0.37 +/- 0.22 to 36.03 +/- 0.54 Bq kg(-1). The mean radium equivalent activity, external hazard index and terrestrial absorbed dose rate for the area under study are 498 Bq kg(-1), 1.4 and 219 nGy h(-1), respectively. The annual effective dose to the public was found to be 269 muSv. The present data were compared with data obtained from different countries.
为评估环境放射性和放射健康危害，对土耳其凯斯唐博尔（恰纳卡莱）周边土壤中天然和人为放射性核素的浓度及分布进行了调查。利用高纯锗探测器通过伽马射线光谱仪测定样品中放射性核素的浓度。总体而言，在土壤中发现钍-232的浓度高于铀-238，该地区钍-232和铀-238的活度高于世界平均水平。在所有样品中均检测到铯-137，其活度范围为0.37±0.22至36.03±0.54 Bq kg⁻¹。研究区域的镭当量活度均值、外照射危害指数和陆地吸收剂量率分别为498 Bq kg⁻¹、1.4和219 nGy h⁻¹。发现公众的年有效剂量为269 μSv。将目前的数据与从不同国家获得的数据进行了比较。
