In the case of these items and all other self-contained, tritium-driven glow materials, the radiation from the tritium simply excites a luminescent phosphor coating, causing it to glow.</p>MutholiniSun, 16 Dec 2007 13:06:03 -0000http://www.ohgizmo.com/2007/12/12/litroenergy-promises-12-years-of-free-glowy/#comment-1764931<p>How about mounting this above toilets so we don't have to wiz by ecco-location in the middle of the night?</p>TroyWed, 12 Dec 2007 14:18:34 -0000
