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

Scintillator characteristics

Afterglow: this is a period of time, during which the scintillator emits light after the cessation of exposure to ionizing radiation.

Hydroscopicity: the scintillator reacts with water. Some scintillators are hydroscopic, which leads to the impossibility of their use in wet conditions.

Emitted light wavelength: different scintillators have different light characteristics of the emitted light.

Density: the density depends on the ability to process the scintillator.
