摘　　要：通道式辐射监测系统主要用于检测车辆通过通道时车中是否含有放射性物质。其控制系统的功能是确定系统在什么情况下报警,其中的核心是报警阈值的确定。控制系统分为现场控制系统和中央控制系统。文中先是通过理论分析得出相关的计算方法,最后通过实验确定计算方法是有效的并把相关数据和国家标准相比较,确定系统指标是达到国家相关标准的。The channel radiation detection system is mainly used for detecting radioactive substances in the car through the channel. Its control system is to determine under which circumstances the system alarms. The core is the alarm threshold value determination. The control system is divided into field control system and central control system. In the first, the paper gets the calculation method through theoretical analysis. Finally the method is proved to be effective by experiment. Related data is compared to national standard. The result shows that the system index is up to national standards.
