  3. Tritium radioluminescence - Wikipedia

    en.wikipedia.org/wiki/Tritium_radioluminescence

    Tritium is the only radiation source used in radioluminescent light sources today due to its low radiological toxicity and commercial availability. [3] Various preparations of the phosphor compound can be used to produce different colors of light. For example, doping zinc sulfide phosphor with different metals can change the emission wavelength ...

  4. Radioluminescence - Wikipedia

    en.wikipedia.org/wiki/Radioluminescence

    The continuous radioactive decay of the isotope's atoms releases radiation particles which strike the molecules of the phosphor, causing them to emit light. The constant bombardment by radioactive particles causes the chemical breakdown of many types of phosphor, so radioluminescent paints lose some of their luminosity during their working life.

    Chemiluminescence kites, [17] emergency lighting, glow sticks [18] (party decorations). Combustion analysis: Certain free radical species (such as • CH and • OH) give off radiation at specific wavelengths. The heat release rate is calculated by measuring the amount of light radiated from a flame at those wavelengths. [19] Children's toys.
