Tritium radioluminescence is the use of gaseous tritium, a radioactive isotope of hydrogen, to create visible light.Tritium emits electrons through beta decay and, when they interact with a phosphor material, light is emitted through the process of phosphorescence.The overall process of using a radioactive material to excite a phosphor and ultimately generate light is called radioluminescence. 3.
