Radioluminescence
Encyclopedia : R : RA : RAD : Radioluminescence
Radioluminescence is the phenomenon by which luminescence is produced in a material by the bombardment of ionizing radiation such as beta particles. An example of a common radioluminescent material is the tritium-excited luminous paints used on watch dials and gun sights, another is the now-disused mixture of radium and copper-doped zinc sulfide paint used historically to paint clock dials.
