摘要

将Geant4模拟应用于校正体积γ射线源检测中的重合求和（CS）效应，并将该技术应用于152Eu标准源。放射源是一个圆柱形、矩形和Marinelli烧杯，每个烧杯的体积不同。放射性核素轨道（RT）包括符合和和无符合和的单能轨道。将两种方法得到的结果与实验数据和改进的圆柱γ射线源KORSUM程序进行了比较。比较表明，本研究所采用的方法对大体积γ射线源的重合求和校正是有用的。此外，与依赖于总效率计算的技术相比，该技术所需的计算时间要少得多。

Coincidence Summing Factor Calculation for Volumetric γ-ray Sources Using Geant4 Simulation

Geant4 simulation was applied to correct the coincidence summing (CS) effect in detecting a volumetric γ-ray sources, and this technique was applied to a152Eu standard sources. The radioactive sources were a liquid cylindrical, rectangular, and Marinelli beaker shapes of different volume for each one. Radionuclide track (RT) including coincidence summing and monoenergetic track without coincidence summing. The results obtained from two approaches compared with the experimental data and the modified KORSUM code for cylindrical γ-ray source. The comparison showed that the adopted method in this investigation is useful for coincidence summing corrections for a voluminous γ-ray sources.Moreover, this technique requires far less computation time than the techniques that depend on the calculation of total efficiency.
