摘要

灵敏度是 γ 射线密度测量系统设计的重要目标之一

本文利用 Monte Carlo 数值方法模拟分析了影响系统灵敏度的各种因素

探讨了提高灵敏度的相关措施。对于设计利用γ 射线与物质相互作用原理探测相关物理量的其他仪器设备也有一定的指导意义。

Abstract

This article analyzed the relationship between sensitivity of a γ -ray density meter and the radiation source. All work was based on the numeric simulation by GEANT4 system. We conclude that a lower energy radiation source gives higher sensitivity

and the position and collimation characteristic of the source have little influence on sensitivity of the system.
