Abstract

Early Warning Environmental Radiation Monitoring Station, used ONLINE environmental radiation monitoring and early warning network, has high sensitive radiation detection and it can send the alarm signal quickly by the internet network to the emergency management office. Its gamma probes are one NaI(Tl) detector and three GM detectors. The NaI(TL) detector is used to monitor spectrum environmental radiation and identify the isotopes, the other are used to detect high dose rate of gamma rays. This instrument must tolerate a wide range of ambient temperature and strong temperature slopes when used in outdoor. However, the gain of photomultiplier tube, amplifier and ADC must be stabilized by pulsed LEDs used as precision reference light sources.
