It makes use of a scintillator, which is a material which emits light upon excitation from a radiation source. The scintillation counter adds a light detecting device like a photodetector, charge-coupled device camera, or photodiode to allow the user to measure the output light from the scintillator and convert it into an electrical signal. The signal can then be analyzed to determine the intensity and energy level of the radiation source.
