    Does anyone remember the 'Beta Lights' popular in the 1980's? These were phosphorescent lined glass vials filled with Tritium (Hydrogen 3), which decays with the emission of a Beta particle (electron) into Helium 3, with a half life of 14 years or so. The phosphorescent light was usually green, though there was no reason not to use the white found in florescent lights, as a fast electron crashing into the phosphorescent material is what causes the light emission in both.
