Measures 511 keV annihilation photons to determine the concentration of positrons in the duct or stack. With each radioactive decay, F-18 or other, PET-nuclides emit a positron which annihilates via the simultaneous emission of two 511keV gamma quanta under 180°.
  • Extremely low coincidence background
  • Signal-to-background ratio enhanced between 1 and 2 orders of magnitude (as compared to standard counting systems)
  • Detection limits well below 1 kBq/m3
  • Total rejection of gammas from outside the active detection volume
  • No lead shielding necessary
  • Easy calibration using a point source (i.e. Ge-68) on the outer surface of the duct
  • Large scintillation detectors are mounted outside the stack
  • Versatile Windows based software for operation and report generation
  • Graphic display of last 24 hours/6 days
  • Immediate alarm generation
  • Optional DDE exchange with monitoring program
  • Optional data export to spread sheet program
  • Optional advanced long term data storage and display program “NetView”
  • Sturdy aluminum frame
  • Stainless steel fittings
  • Corrosion free
  • Suitable for indoor and outdoor applications
  • White, UV-stabilized PVC cover panels with increased impact strength
  • Variable height with easily adjustable feet
