Abstract

Example embodiments of a radiation detection system including a detector is described. The detector can include a scintillator, a sensor, and a light source. The radiation detection system can further include a controller programmed to control the light source to expose the scintillator to a light to saturate traps in the scintillator. In some embodiments, the detector can further include a second light source, and the controller is programmed to control the second light source to expose the scintillator to a second light to detrap afterglow traps in the scintillator.
