06 Jul 2020 Description NaI(Tl) or sodium iodide doped with thallium: NaI(Tl) is by far the most widely used scintillator material. It is available in single crystal form or the more rugged polycrystalline form (used in high vibration environments, e.g. wireline logging in the oil industry). Crystals with a higher level of doping are used in X-ray detectors with high spectrometric quality. Other applications include nuclear medicine, basic research, environmental monitoring, and aerial surveys. Sodium iodide can be used both as single crystals and as polycrystals for this purpose. The iodine provides most of the stopping power in sodium iodide (since it has a high Z = 53). These crystalline scintillators are characterized by high density, high atomic number, and pulse decay times of approximately 1 microsecond (~ 10-6 sec). The wavelength of maximum emission is 415 nm. NaI(Tl) is the most widely used scintillation material.Sodium iodide activated with a trace amount of thallium converts about 15% of fast particle energy into light, a figure that is the highest among commonly used scintillation materials. The high atomic number of the iodine component ensures that large crystals of sodium iodide will fully absorb the energy of a large fraction of all incident gamma rays. NaI(Tl) detectors have other advantages, very large crystals can be grown and raw material is not expensive, which makes high efficiency for gamma ray detection is easily achieved. Sodium Iodide Thallium-doped crystals have a very high luminescence (scintillation) efficiency and are available in a wide variety of sizes and geometries. Because of all its advatnages, NaI(Tl) detectors became very soon one of the most convenient options for many applications, from radiology to environmental monitoring. Parameter
