Where do I get Tritium?

[inuboi8]

there is some faintly radioactive substance they put in pistol sights so that you can see the 3 dots at night, they literally let off their own glow and they havnet given any NRA members cancer i forget what its called tho...try a google search that deals with luminecent gun sight paints

The pistol sites are tritium, the sights are drilled and have small vials of tritium in them. I have a set on one of my guns.

Beta emitters give off electrons.

I'm aware. But electrons are known for exciting phosphors. That's the basis behind the CRT monitor, AND the tritium vials.
