Radioluminescent 1.2 Curie 4" x .2" Tritium vials are simply tritium gas filled thin glass vials whose inner surface are coated with a phosphor. The "gaseous tritium light source" vial shown here is 1.5 years old.

Radioluminescence is the phenomenon by which luminescence is produced in a material by the bombardment of ionizing radiation such as beta particles. Examples of common radioluminescent products are the tritium-excited light sources used on watch dials and gun sights, and the now-disused mixture of radium and copper-doped zinc sulfide luminous paint used historically to paint clock dials.
