Sodium Iodide crystals doped with Thallium (or NaI(Tl) crystals) have a very high scintillation or luminescence efficiency and a good energy resolution, NaI(Tl) scintillators has the largest light-out and an emission range well matched to photomultipliers with bialkali photocathodes at a high efficiency, and combination with its easy availability of variety size and geometries and low cost, NaI(Tl) scintillators has become most widely used scintillators. NaI(Tl) crystals is a kind of highly hygroscopic materials, it must be put in a hermetical sealing housing in using.

The rectangular shaped NaI(Tl) scintillator is an usual type of GAMMA ray detector, Its NaI(Tl) crystal is rectangular shaped and encapsulated in aluminum or steel cases with an optical windows for Photomultiplier Tube (PMT) coupling. The Photomultiplier Tube (PMT) could be integrated to NaI(Tl) crystals if it is required. Rectangular shaped NaI(Tl) scintillators are widely used for in scintillation measurement or scintillation spectrometer detector for ordinary GAMMA ray.  Hangzhou Shalom EO offers the stocked standard rectangular NaI(Tl) scintilaltion crystals and detectors with fast delivery, and we also offers the customized NaI(Tl) crystals upon cusomer's request.
