• Backpack detection system can be used turned on behind a windshield in a moving vehicle as a radiation detection system
• Easy user interface (automatic/manual reset background, automatic /manual start/stop radionuclides dentification)
• Gamma-ray detector based on NaI crystal
• The Neutrons detector based on two He-3 tubes (BDKN-05)
• System is scalable in volume and in number of detectors
• MCA, voltage divider and LED stabilization system in the tube base
• Highly-sensitive detection at a distance of both gamma and neutron sources (1-25) nSv/hr above background gamma and 40 nSv/hr for neutrons of Cf-252 using both gamma and neutron detectors simultaneously
• Data collection unit pocket size handheld PC (HPC)
• Connection to HPC via Bluetooth interface
• Data evaluation software on HPC: Real time spectrum recording, dose rate calculation and isotope identification, audio alarms if elevated radiation, sound pattern depending of the isotope identified
• Integrated GPS positioning
• Storing spectra and count rates for about 40 hours of scanning
• Fast response time (update 300 ms)
• Alarm annunciation: Audio signal, voice output on HPC speaker or wireless headset, visual indication on HPC’s screen
• HPC is used as an external panel that is placed in a bag on a belt without cable’s connections
