A hybrid sourceless efficiency calibration method for detecting nonuniform and irregular radioactive sources

The data set is mainly the Monte Carlo simulation data and the hybrid sourceless efficiency calibration method calculation data, and through the processing of the experimental data to get the relevant result analysis diagram. It mainly includes relative error of the geometric efficiency between the cylindrical detector and the equivalent spherical detector for gamma rays at 609 keV, relative error of the geometric efficiency between the cuboid detector and the equivalent spherical detector for gamma rays at 609 keV, relative errors in the full energy peak efficiency of the cuboid detector for the small cells between the Monte Carlo simulation and the analytical calculation, relative errors in the full energy peak efficiency of the cylindrical detector for the small cells between the Monte Carlo simulation and the analytical calculation, the full energy peak efficiency of the validation experiment.本数据集主要包含蒙特卡洛（Monte Carlo）模拟数据与混合无源效率校准方法计算数据，并通过实验数据处理得到相关结果分析图。具体涵盖以下内容：609 keV伽马射线下圆柱形探测器与等效球形探测器（equivalent spherical detector）的几何效率（geometric efficiency）相对误差；609 keV伽马射线下长方体探测器与等效球形探测器的几何效率相对误差；针对小型样品池的长方体探测器全能峰效率（full energy peak efficiency）在蒙特卡洛模拟与解析计算间的相对误差；针对小型样品池的圆柱形探测器全能峰效率在蒙特卡洛模拟与解析计算间的相对误差；以及验证实验的全能峰效率。
