The United Radium Corp did develop a radio-luminiscent powder about a hundred years ago which would pigment a paint so to apply to watch dials. The radio source was of course radium with a halflife= 1500y. so radium powder mixed with the phorsphor would make an everlasting glow. Unfortuntely several women got sick and died and they sued that company's pants off. Using encapsulated tritium may sound safer, not a beta emitter, but still dangerous if such particulate is inhaled or ingested. If lead paint is banned surely will this for consumer use.
I do see this possibley being used as a sign (that said company also painted EXIT signs too) as well as a safety tape for poweroutages.
