Was wondering about the use of tritium as "lume" and stumbled over this article.Thought I'd share it.

Yes, interesting indeed. I knew little about lume and now I know a little more thanks to the OP.

Good read. Thanks for posting it. I remember reading a story about the "radium girls" in the past but it did not cover the lume history to present day.

I have a marathon dial with tritium tubes that i'm selling on the bay.   Even has tritium glass tubes on the hour and minute hands.  I think they last 25 years and these are about 8 years old.
