- Model PM520 - Radiation Monitoring System


Radiation Monitoring System PM520 is designed for continuous gamma and neutron radiation monitoring of different facilities where radioactive sources are stored or processed.

PM520 can be deployed in several separate locations or in passageways outdoors. Apart from other systems, PM520 has flexible configuration and uses up to 8 wall-mounted Gamma and Neutron Probes of different sensitivities and measurement ranges, main processing unit and remote PC for operation monitoring control with maximum distance between probes and unit up 1000 m. This configuration allows extending the range of controlled area with possibility of transferring measurement data to the single coordination center.

Radiation Monitoring System can be used in different areas: nuclear facilities, waste management, areas and buildings with limited access, border/airport check points, places of storage and use of nuclear materials.

PM520 main processing unit has two independent alarm thresholds ATTENTION and DANGER. It processes dose rate measurements from distributed radiation probes over the area and alerts users if thresholds are above the average background by visual and sound alarms. Thus PM520 can be used even by untrained personnel.

Thresholds can be calculated automatically during self-calibration or user programmable. Optionally, PM520 can be supplied with PC control unit with the installed Configuration Software for the adjusting settings, sensitivity and alarming thresholds of particular detectors. Additionally PM520 can be equipped with external alarming devices and has possibility for integration into Customer security system.

PM520 represents multipurpose system with configurable design that can be customized to solve various radiation protection tasks on the Customer facilities.
