摘要
构建了一套基于时间戳的时间间隔分析法放射性核素监测装置,包含复合晶体探测器、核信号模拟处理电路、具有时间戳功能的高速数据采集卡等硬件部分,上位机界面基于C#语言的开发而成,获取时间间隔分布统计信息,实现监测级联衰变的目标放射性核素浓度.实验结果表明:该装置结构简单、能够在多核素混合场条件下提取需要测量的核素,有较强的实用价值.
Abstract
This thesis constructs a set of time interval analysis radionuclide monitoring device based on time stamp,which contains hardware parts such as composite crystal detector,nuclear signal analog processing circuit,high-speed data acquisition card with time stamp function,etc.The upper computer interface is developed based on the C#language,which obtains the statistical information of time interval distribution and realizes the monitoring of the concentration of the target radionuclide in the cascade decay.The experimental results show that the device is simple in structure,capable of extracting the nuclides to be measured under the condition of multi-nuclide mixed field,and has strong practical value.
