Pedestrian RMDS

Radioactive Material Detector System


    RMDS Portal is an Advanced Spectroscopy Portal (ASP) designed for walk through and second tier (static) scanning. The system at it various versions integrates up to 8 NaI(T1) (Gamma) and 2 3He (Neutron) detectors into two pillars. RMDS was designed specifically for Homeland Security Applications, taking into consideration the rigorous challenging demands of this evolving market. RMDS are primarily intended to be placed at border crossings and airports. The system is also suitable for mass population inspection, in case of nuclear accident or radiological terroristic act. RMDS is designed to fully comply with the ANSI N42.38 standard.
