REN300A on-line radiation safety alarm is a new type of x-gamma radiation continuous monitoring and alarm device. It uses a special designed preamplifier circuit. It has the characteristics of high sensitivity, easy operation, automatic display and ultra-threshold alarm. It can give the radiation dose rate of x-gamma in real time. Considering the need of field operation and emergency response, the host computer is installed in the radiation field to realize real-time monitoring and local alarm, and the automatic monitoring of the general control room is realized by RS485 communication. RenriArea radiation area monitoring software can be selected according to field requirements. The software can store historical data of 30 probes for more than 5 years continuously, and provide real-time data acquisition and spectra.
The instrument is widely used in radioactive waste depots, industrial non-destructive testing, gamma knife treatment, isotope application, gamma irradiation, hospital X-ray diagnosis, accelerator, Xray device, nuclear power plant and other radioactive sites. It reminds staff that the radiation source or radiation device has been working or leaking, so as to protect them from radiation hazards.
