摘要
利用蒙特卡罗工具Geant4模拟了^(137)Cs和^(60)Co这两种放射源的几何形状以及探测距离这两个因素对γ射线在NaI(Tl)闪烁体探测器内能量沉积的影响。研究结果表明,当放射源的几何形状不一样时,不同的核素在峰总比达到最大时的探测距离不一样,模拟结果为放射性测量提供了参考。
By using Mont Carlo kit Geant4 it has been studied that both the shape of source and detecting distance are able to affect the deposited energy in NaI (Tl) scintillation detector. The simulation shows that the measurement distance of radionuclides with reaching maximum peak - to - gross ratio varies with different geometry of sources.
