Abstract:
A radiation detection system comprising:a scintillator for emitting flashes of light in response to radiation impinging upon the scintillator;a light sensing device positioned proximate the scintillator to receive the flashes of light, the light sensing device producing an electrical output having a magnitude correlated to the light produced by the crystal;a light source for emitting photons into the scintillator that are not detectable by the light sensing device but which cause the scintillator to fluoresce at a wavelength detectable by the light sensing device; anda processor that monitors the scintillator output attributable to the photon emitting light source and effects adjustment of the gain of the system in response to changes in the scintillator output attributable to the photon emitting light source.
