The concentrations of natural radionuclides in surface soils around Adana, Turkey were determined using gamma ray spectrometry with an HPGe detector. The natural gamma ray radioactivity of the terrestrial radionuclides in air was calculated throughout different areas of Adana. The average activity concentrations of (238)U, (232)Th and (40)K were found to be 17.6, 21.1 and 297.5 Bq kg(-1), respectively. Outdoor gamma dose measurements in air 1m above ground level were determined by using a portable gamma scintillation detector. The gamma dose measurements in air were taken from the same places where soil samples were taken. Average outdoor gamma dose rates in sample stations were determined as 67 nGy h(-1). The annual effective dose to the public was found to be 82 microSv.
利用配备高纯锗探测器的伽马射线能谱仪测定了土耳其阿达纳周边表层土壤中天然放射性核素的浓度。计算了阿达纳不同区域空气中陆地放射性核素的天然伽马射线放射性。发现（238）U、（232）Th和（40）K的平均活度浓度分别为17.6、21.1和297.5 Bq kg⁻¹。使用便携式伽马闪烁探测器测定了地面上方1米处空气中的室外伽马剂量。空气中的伽马剂量测量是在采集土壤样品的相同地点进行的。样本站的平均室外伽马剂量率确定为67 nGy h⁻¹。发现公众的年有效剂量为82微希沃特。
