Saveh_Soil_Radioactivity_Data_Baseline

Gamma spectrometry raw data and radiological hazard parameters for soil samples collected from Saveh, Iran This dataset contains the raw gamma spectrometry results and derived radiological parameters for surface soil samples collected from seven locations in Saveh, Iran. The activity concentrations of naturally occurring radionuclides including Ra-226, Th-232 and K-40 were measured using a high-purity germanium (HPGe) detector with 40% relative efficiency and a counting time of 86400 seconds. The dataset includes: • Raw activity concentrations (Bq/kg) and their combined uncertainties • Geographic coordinates of sampling locations • Representative gamma peak information (energy, emission probability and net counts) • Absorbed dose rate in air (nGy/h) • Annual effective dose (mSv/y) Activity concentrations were calculated using standard gamma spectrometry equations based on net peak area, detector efficiency, gamma emission probability and counting time. Combined uncertainties include counting statistics, efficiency calibration uncertainty, gamma emission probability and peak fitting uncertainty. This dataset supports the results and conclusions presented in the associated research article and enables reproducibility of the radiological assessment.伊朗萨韦赫地区土壤样品的γ能谱（Gamma Spectrometry）原始数据与放射危害参数 本数据集涵盖伊朗萨韦赫地区7个采样点表层土壤样品的γ能谱原始测试结果及衍生放射学参数。研究采用相对效率为40%的高纯锗（HPGe）探测器，以86400秒的计数时长，对天然放射性核素镭-226（Ra-226）、钍-232（Th-232）及钾-40（K-40）的活度浓度进行了测定。 本数据集包含以下内容： • 原始活度浓度（单位：贝可/千克，Bq/kg）及其合成不确定度 • 采样点的地理坐标 • 典型γ能谱峰信息（能量、发射概率与净计数） • 空气中吸收剂量率（单位：纳戈瑞/小时，nGy/h） • 年有效剂量（单位：毫希沃特/年，mSv/y） 活度浓度的计算基于净峰面积、探测器效率、γ射线发射概率与计数时长，采用标准γ能谱分析公式完成。合成不确定度涵盖计数统计误差、效率刻度不确定度、γ射线发射概率不确定度及峰拟合不确定度。 本数据集可为相关研究论文中的结果与结论提供支撑，并可实现放射学评估的可重复性研究。
