Research on Simulation Calibration Method for In-situ Measurement of Surface Radioactivity in Nuclear Emergency Based on HPGe γ Spectrometer

This data set provides data support for the paper " Research on Simulation Calibration Method for In-situ Measurement of Surface Radioactivity in Nuclear Emergency Based on HPGe γ Spectrometer", including the codes and running results of Monte Carlo simulation. The simulation object is the detection efficiency of the spectrometer when the HPGe γ spectrometer is erected at a height of 1 m from the ground, and the radioactive point sources with different energy γ rays located at different positions. The horizontal distance extends from 0m to 5m with an interval of 20cm. The ray energy includes 228 keV, 364 keV, 530 keV, 662 keV, 1173 keV, 1332 keV, 1691 keV.本数据集为论文《基于HPGe γ能谱仪的核应急现场表面放射性原位测量模拟校准方法研究》提供数据支撑，包含蒙特卡洛（Monte Carlo）模拟的代码与运行结果。本次模拟的对象为HPGe γ能谱仪距地面1m高度架设时，不同位置、不同能量γ射线的放射性点源对应的探测器探测效率。其中，点源与探测器的水平距离跨度为0m至5m，步长为20cm；射线能量涵盖228 keV、364 keV、530 keV、662 keV、1173 keV、1332 keV、1691 keV。
