It would seem that Horace is thinking of a large amount of tritium. Sure. For that, absolutely not amateur, and the cost would be very high and the regulation strict, anyway. Tritium is *really* not cheap, I'm sure.
I expect the best source of tritium for an amateur experiment would be a tritium exit sign. Look up "tritium exit sign" on Google and you will see. They cost about $140. There are 2 million in use in the U.S. See:

Naturally, there is only a small amount of tritium in them, but as Abd noted, a small amount is what you want.
It is probably against the law to break them apart to get at the tritium. Unfortunately, it does not take much to stop the particles from it, as everyone here knows.
Tritium wrist watches are also available. - Jed
