车辆γ监测系统测量下限优化设计

车辆γ监测系统广泛布置于核电厂、海关、钢厂及安保场所出入口,用于监测出入车辆是否携带放射性物质或受到放射性沾染。将3套车辆γ监测系统进行组合设置,车辆通过时γ监测系统报警信号与报警信号产生的时序逻辑顺序进行复合判断。应用车辆γ监测通道组合设置及修改报警阈值,能有效地降低车辆γ监测系统的测量下限。

Vehicle Gamma Monitoring System Lower Limit Detection Optimization

The vehicle gamma monitoring system is widely deployed in nuclear power plant, customs, steel mills and places of security passageway., used to monitor access to the vehicle carrying radioactive materials or radioactive contamination.The new design uses the 3 sets of vehicle gamma monitoring systems combined.When the vehicle passes, the radiation monitoring systems use the alarm signals and the signals on the temporal logic sequence of composite judgment to make decision.Using the combination of vehicle gamma monitoring systems and modified the alarm threshold can effectively reduce the lower limit detect of the vehicle gamma monitoring system.
