RADIATION PORTAL MONITORS are dedicated for detection and localisation of radioactive and nuclear materials (gamma) in medicine institutions, disposal facilities, scrap processing sites, incineration plants, conveyor and baggage systems.

A special feature of the system is the signalization of threshold overflow. Alarm levels in the Search Mode are derived from the ambient background. When the instrument runs through background calibration, it acquires a background reading and calculates the alarm levels automatically based on the value of n coefficient set by the user.
