General Encapsulated NaI(Tl) Scintillator
The general encapsulated NaI(Tl) scintillator is a Gamma-ray detector whose NaI(Tl) crystal is cut into a cylinder and housed in aluminum cases.
For measurements, the radiation can enter from one face of the cylinder or the side, and light output can be obtained from the optical window mounted at the other face.
General encapsulated NaI(Tl) scintillator is used for scintillation measurement or scintillation spectrometer detector for ordinary Gamma-ray because its shape enables it to obtain a uniform light output and the best energy resolution.
