Natural background gamma radiation was measured along roads in the environs of Çanakkale region by using a car-borne spectrometer system with a plastic gamma radiation detector. In addition, activity concentrations of ²³⁸U, ²²⁶Ra, ²³²Th and ⁴⁰K in soil samples from the Çanakkale region were determined by using a gamma spectrometer with an HPGe detector. A total of 92,856 data of the background gamma dose rate were collected for the Çanakkale region. The background gamma dose rate of the Çanakkale region was mapped using ArcGIS software, applying the geostatistical inverse distance-weighted method. The average and population-weighted average of the gamma dose are 55.4 and 40.6 nGy h⁻¹, respectively. The corresponding average annual effective dose to the public ranged from 26.6 to 96.8 µSv.
利用配备塑料伽马辐射探测器的车载光谱仪系统,对恰纳卡莱地区周边道路沿线的天然本底伽马辐射进行了测量。此外,使用配备高纯锗探测器的伽马光谱仪测定了恰纳卡莱地区土壤样品中²³⁸U、²²⁶Ra、²³²Th和⁴⁰K的活度浓度。共收集了恰纳卡莱地区92,856个本底伽马剂量率数据。运用地理统计反距离加权法,使用ArcGIS软件绘制了恰纳卡莱地区的本底伽马剂量率图。伽马剂量的平均值和人口加权平均值分别为55.4和40.6 nGy h⁻¹。公众相应的年平均有效剂量范围为26.6至96.8 µSv。
