Tritium Light Sources

I want one, definitely.

So far the only source i found for that in europe would be ordering over ebay from great brittain which yields pretty high transport costs.
Imagine a small light that glows for more than 10 years constantly
I would feel like Frodo, when he received the light of Eärendil.
Tritium gas ( H3 ) is a radioactive form of ordinary Hydrogen gas ( H2 ).
High pressure Tritium gas is sealed inside these small borosilicate glass vials, and continuously emits low energy Beta radiation (electrons). These electrons impact a special phosphor coating on the inside of the tube, which in turn emits a visible GREEN glow.

tritium is hazardous when you drink it, eat it, breathe it in or you absorb it through your skin.
Tritium is not considered an external hazard, but is an internal one. It has a radioactive half life of about 12 years which means it stays around in the environment for a long time. It has the unusual properties of extremely rapid transport in the environment, quick uptake by humans, fast exchange mechanisms with other hydrogen atoms, and the ability to bind with organic molecules during cell formation and cell metabolism.
The key words here are "very weak" - the beta particles are unable to penetrate even thin layers of solid material and are easily stopped by human skin. A report by the Public Health Division of the Department of Human Services in Victoria, Australia on the effects of wearing a plastic watch containing tritium concluded that the health implications were negligible. Rather more prejudicial to physical well-being is the other common use of tritium, as outlined by the Federation of American Scientists
