Vehicle Radiation Monitors (based on AT2327 Alarm Dosimeter)

Detection of gamma and neutron radiation sources in vehicles crossing access control points.

 

  • Screening of the rear wall of the gamma radiation detection unit by lead plates
  • Automatic adjustment of set threshold levels according to changes in natural radiation background
  • Modular system design
  • High reliability and self-check function
  • Backup power source
  • Automatic data logging
  • Optional CCTV connectivity
