SPIR-IDENT system is a movable radiation monitoring system, developed for vehicle, helicopter and aircraft.

It is a ruggerized and friendly deployable equipment with the higher existing capability for both detection and identification or radioactive sources.

This system especially allows to detect artificial gamma isotopes among varying natural isotopes when used as an airborne or carborne system for the purpose of contamination evaluation and unattended source search.

SPIR-IDENT also exists as pedestrian portal monitor.
