PRODUCT:  NaI(Tl)



Introduction:

NaI(Tl) crystal is the most widely used scintillation material, it is growed based on NaI substrate doped certain concentration thallium, and among scintillators, it has the greatest light output, convenient emission range coincident with maximum efficiency region of photomultiplier(PMT) with bialkali photocatodes, and no obvious self absorption in glow wavelength, for X rays and γ rays both have a good resolution。
