Overview

Sodium iodide crystal is a kind of scintillation crystal with excellent performance. It is grown with NaI as the substrate material mixed with TI of appropriate concentration, and it has a maximum emission wavelength of 415 nm, matching well with the photocathode of the photomultiplier tubes, having high luminous efficiency and good resolving power of X rays and gamma rays.
