Scintillation Detectors

Scintillation detectors with NaI(Tl), LaBr₃(Ce), CeBr₃ or SrI₂ crystals for gamma spectrometry from 20 keV to 3 MeV.

Applications include radiation monitoring, radiation logging in boreholes, scintillation spectrometry, detection of alpha and beta radiation, tomography and high-energy physics. The scintillator crystal is optically connected to a photomultiplier tube.

  • Crystal materials such as NaI(Tl), LaBr₃(Ce), CeBr₃ or SrI₂, depending on customer requirements
  • Energy range 20 keV to 3 MeV
  • LaBr₃ and SrI₂ for high resolution, CeBr₃ and SrI₂ for low background and MDA
  • Crystal and photomultiplier tube wrapped in an antimagnetic screen in a sealed aluminium case
