Abstract

A radiation detector may include a scintillator, a light source, and a sensor. The scintillator may include various scintillation materials capable of converting non-visible radiation (incoming radiation) into visible light. The sensor may be placed in adjacent or in close proximity to the scintillator, such that any converted visible light may be detected or measured by the sensor. The light source may be placed in adjacent or in close proximity to the scintillator, such that light from the light source may interact with defects in the scintillator to minimize interference on the conversion of non-visible radiation into visible light caused by the defects.
