The modular system adapts to different needs, allowing for a scalable operation dependent upon the types of traffic moving through the portal.
  • Large area plastic scintillation detectors for Γ radiation detection with data transfer via RS 485 from the detector array to the operators room up to 1000mUV-stabilized PE panel housing stays corrosion free even under demanding conditions
  • Low energetic radiation can penetrate PE material easily; not shielded from the sensitive large area gamma radiation detector
  • Immediate separation between NORM and artificial radiation through NBR (Natural Background Rejection) technology
  • Optional moderated He3 counting tube Neutron radiation detectors
  • Effective false alarm suppression through automatic background radiation learning and SIGMA alarm threshold setting
  • ADF (Advanced Digital Filter), an intelligent ratemeter function with a self adjusting time constant, providing automatic adaption to the velocity of a moving source or detector and to the variable intensity of radiation
  • Recognition of objects plus speed alarm triggering
  • Control of traffic lights, audible alarm indication via horn or visible via alarm lights
  • Windows™ XP based controller model FHT 8000 with 32 bit SGS2 software package
  • Automated protocol printing also on a network printer
