        description:

        Introduction: NaI (TI) is a kind of scintillation crystal with good performance. It is grown by host material sodium iodide doped with appropriate percentage of thallium. The main emission wavelength is 415nm, which well matched with the working wavelength of photomultiplier tubes (PMTs). It  has very high luminescence efficiency and exhibits no significant self absorption of the scintillation light and has good resolution ability to X-ray and γ-ray.

         

        Main Advantage:

        1.Has highest luminescence efficiency among the current scintillation crystals.

        2.The emission wavelength(415nm)match well with the working wavelength of photomultiplier tubes (PMTs).

        3.Low cost.

        4.High hygroscopic.

        5. Main ApplicationOil well logging, geophysical survey, nuclear medicine, environmental monitoring, high-energy physics, etc.
