AT2329 Radiation Portal Monitor

Highly sensitive non-intrusive system providing continuous radiation monitoring to detect gamma and neutron radiation sources and nuclear materials inside vehicles and cargo crossing the checkpoints.

Smart detection units with large-volume detectors and efficient algorithms allow fast and precise detection of radiation sources with definition of its type (categorization) as a natural or an artificial.


  • ANSI N42.35 compliant
  • Gamma and neutron sensitive channels
  • Categorization (differentiation) of radiation sources into natural and artificial
  • High reliability and lifetime
  • Backup power source
  • Automatic data logging
  • Parallel operation with CCTV
