Monocrystalline sodium iodide activated with thallium NaI (Tl), is currently the most common of all scintillator materials. The scintillator NaI (Tl) differs high light yield. For the formation of a single photon therein spent about 25 eV. The luminescence spectrum is in good agreement with the spectral sensitivity bialkali photocathode of photomultiplier tubes. The scintillator NaI (Tl) has high transparency to the light of their own emitting. A large value of Z iodine in the crystals NaI (Tl) results in a high detection efficiency of the gamma radiation. The decay time of light is constant for crystal NaI (Tl), is approximately 0.23 microseconds. Conventional charge-sensitive preamplifiers convert it into a voltage pulse output with a rise time of approximately 0.5 microseconds.
