Radiation Portal Monitoring System

The RS-400 system is a 4 PMT based super-coincidence, fully digital, radiation portal monitoring system.

The system is specially designed to overcome the difficult operating conditions experienced by many industries, including steel and scrap facilities, that need to monitor incoming, or outgoing, shipments for potential radioactive contamination.

The RS-400 offers extremely high sensitivity performance with minimum false and nuisance alarms due to it’s advanced digital design and spectral analysis. This system uses large volume detectors for optimum vehicle coverage. Typically, long detectors suffer substantially from signal loss using conventional technology, as a result RSI has developed a 4PMT technology utilising PMTs at both ends of the detector for greatly improved signal collection and spectral shape.

The system is fully modular which makes it easily configurable to suit local logistics and permits fast, easy maintenance. The system operates independently and has direct Ethernet connectivity to plant networks allowing for a fully integrated plant design with RSO overview on all installed systems. USB/Serial connectivity also enables system configuration to suit user needs for local displays, local or network printers, scale computer integration etc.
