AT6101C, AT6101CM Spectroscopic Backpacks

Inconspicuous search and detection of radiation sources with radionuclide identification and classification.

An effective technical solution to prevent illegal traffic of radioactive materials, investigation of potentially contaminated terrains, and security survey at mass events.

  • High reliability and proven customer satisfaction
  • 20 hours of operation time, memory for 130 hours of scan time
  • Rugged Android smartphone (4.7″ or 6″) for control and indication
  • Automatic simultaneous gamma and neutron radiation scanning with radionuclide identification
  • Continuous recording of scanning data with GPS-referencing for further analysis
  • Expandable dose rate measuring range of gamma radiation to 10 Sv/h
  • “GARM” software for further data processing and analysis
