研制的用于核设施周围环境γ辐射和事故应急连续监测系统由高气压电离室、集成化弱电流放大器、Ｖ－Ｆ变换器和智能化数据记录仪组成。通过标准ＲＳ－２３２－Ｃ接口转储到计算机上进行数据处理和绘图。该系统具有超阈报警，采集记录探测器输出信号和温度等功能。采用了高绝缘自动量程转换开关，测量范围为１０ｎＧｙ·ｈ－１－２０ｍＧｙ·ｈ－１。监测系统经长时间现场考验，工作性能稳定。
Developed for nuclear environment surrounding γ radiation and accident emergency monitoring system consists of high pressure ionization chamber, integrated weak current amplifier, V-F converter and intelligent data logger. Data is processed and plotted onto a computer via a standard RS-232-C interface. The system has a threshold alarm, capture and record the detector output signal and temperature and other functions. Using a high insulation automatic range switch, the measurement range of 10nGy · h-1-20mGy · h-1. Monitoring system for a long time on-site test, work performance and stability.
