In this study, the activity concentrations of terrestrial and anthropogenic radionuclides in the soil samples collected from Bafra Kızılırmak Delta were measured by using gamma spectrometry with an NaI(Tl) detector. The average values of activity concentrations of (238)U, (232)Th and (40)K were found to be 37.2±2.8, 33.7±3.1 and 413.0±59.8 Bq kg(-1), respectively. (137)Cs was also measured in some samples. It has a mean value of 13.8±1.0 Bq kg(-1). From the activity concentrations, the absorbed gamma dose rates in outdoor and the corresponding annual effective dose rates and external hazard index (Hex) were estimated.
在本研究中，使用配备碘化钠（铊）探测器的伽马能谱仪，对从巴夫拉基兹尔马克三角洲采集的土壤样本中的天然和人为放射性核素活度浓度进行了测量。发现（238）U、（232）Th和（40）K的活度浓度平均值分别为37.2±2.8、33.7±3.1和413.0±59.8 Bq kg⁻¹。还对部分样本测量了（137）Cs，其平均值为13.8±1.0 Bq kg⁻¹。根据活度浓度，估算了室外的吸收伽马剂量率以及相应的年有效剂量率和外照射危害指数（Hex）。
