  • High light output
  • Available in single crystal & polycrystalline form
  • No significant self absorption of scintillation light
  • Emission spectrum well matched with the sensitivity curve of photomultiplier tubes (PMTs) with bialkali photocathodes

The tellur doped sodium iodine scintillation detector is a hermetically sealed assembly which includes NaI(Tl) crystal, a photomultiplier tube, an internal magnetic/ light shield, an aluminum housing, and a 14-pin connector. It provides high efficiency and uniform response on both the cylindrical and well configurations. These detectors have a proven record of long term reliability and stability. They are widely used for radiation detection.
