A scintillator is a material characterized by the spontaneous emission of electromagnetic radiation, when exposed to ionizing radiation. This behaviour is exploited in scintillation detectors in which a sensor (such as a silicon photomultiplier) is coupled to the material in order to detect the emitted radition.
