NaI(Tl) Scintillation Crystal Radioactive / Nucleonics Level Gauge
NaI(Tl) Scintillator Crystal Radioactive / Nucleonics Level Gauge
The emission maximum of NaI(Tl) crystal is well matched to the sensitivity curve of photomultiplier tubes (PMTs) with bialkali photocathodes.
NaI(Tl) is susceptible to radiation damage, i.e. prolonged exposure to intense radiation degrades the scintillation performance. The crystal should not be exposed to ultraviolet radiation from fluorescent lamps or sunlight.
Scintillation crystals of NaI(Tl) are routinely grown with a potassium content of less than 0.5 ppm, and are appropriate for low background applications. NaI(Tl) crystals are widely used for radiation detection: in nuclear medicine, for environmental monitoring, in nuclear physics, aerial survey, well logging and in many other applications.
