水样γ能谱三种测量方法探测效率对比的模拟分析

Water sample γ simulation analysis of detection efficiency comparison of three energy spectrum measurement methods

作为在有效时间分析水、空气等放射性物质种类的应用技术,γ能谱测量技术可以针对核应急事件评估,修复环境诸多内容,提供准确数据支持。本文以此为切入点,借助MCNP4C软件,将水样作为研究对象,并对三种γ能谱测量技术从探测效率方面进行对比。井型NaI(TI)探测器在本实验中拥有最佳探测效率,在未来核应急快速监测中具有较强的应用价值。

As an application technology for analyzing the types of radioactive substances such as water and air at an effective time,γ energy spectrum measurement technology can provide accurate data support for nuclear emergency assessment and environmental repair. Taking this as the starting point, this paper takes the water sample as the research object with the help of MCNP4 C software, the γenergy spectrum measurement technology is compared in terms of detection efficiency. The well NaI(TI) detector has the best detection efficiency in this experiment and has strong application value in the rapid monitoring of nuclear emergency in the future.
