When ordinary table salt is irradiated, it turns brown due to “color centers” (defects) in the excited-state crystal structure. When the irradiated salt is heated on a hot plate, it gives off flashes of light and turns white as the excited-state crystal returns to the ground state. The thermal fluorescence of irradiated table salt is used to illustrate crystal defects.
