R-online radiation safety alarm is a new type of continuous monitoring and alarm device for x - γ radiation. It adopts a specially designed preamplifier circuit, which has the characteristics of high sensitivity, easy operation, automatic display, data storage, and over threshold alarm. It can provide real-time x - γ radiation dose rate. Considering the needs of on-site operation, rapid emergency response, and convenient maintenance, a host is installed on site to achieve real-time monitoring and local alarm. Radiation area monitoring software can be selected according to on-site requirements, which can continuously store historical data of 30 probes for more than 5 years.


Typical applications:
The R-online radiation safety alarm is mainly used to monitor radioactive sites with radiation sources. By measuring the radiation dose rate, it reminds workers that the radiation source or radiation device is in a working or leaking state, protecting them from radiation hazards. Applicable places:
Radiation protection monitoring in fields such as environmental monitoring, health and epidemic prevention, hospital gamma knife treatment, isotope application, gamma irradiation, hospital X-ray diagnosis, cobalt treatment, non-destructive testing, import and export inspection, radiation medicine, building materials, petrochemicals, geological survey, docks, ports, scrap steel, nuclear laboratories, etc.
Performance advantages:
1. The R-online radiation safety alarm adopts a high-speed embedded microprocessor and a graphical dot matrix 160 × 160 LCD display with user-friendly input
2. Chinese menu style operating interface.
3. Three alarm modes, suitable for the needs of various radiation safety alarm locations.
4. A host can host more than 30 detectors.
5. Multiple interface outputs and inputs, can form interlocking systems with X-Ray or lead doors, etc.
6. Real time sampling, data is processed and refreshed quickly every second.
7. Calendar clock function, with fault self recovery function.
8. Detector malfunction indication
9. Data can be output to other devices
10. Wall mounted main control box, easy to install.
11. Communication method: Standard RS485 interface, MODBUS communication protocol, transmission distance up to 800 meters.
Optional GPRS wireless network transmission for remote networking (optional).
12. Can be combined with radiation area monitoring software to form an online x - γ radiation monitoring system.
