Scintillator – this material, which emits light when it absorbs ionizing radiation. There are quite a few scintillators of various chemical compositions.: NaI, CsI(OF), CsI(Already) CdWo4, CdF2, BGO, ZnS(Ag).

Characteristics of scintillators

afterglow: it's a period of time, during which the scintillator emits light after the termination of irradiation with ionizing radiation.

hygroscopicity: scintillator reacts with water. Some scintillators are hydroscopic, which makes it impossible to use them in wet conditions..

Wavelength of emitted light: different scintillators have different light characteristics of emitted light.

Density: the possibility of processing the scintillator depends on the density.
