According to the article referenced by John Ruum, the tritium would be

Getting tritium to emit alpha particles would be a really neat trick, and
worthy of a Nobel Prize :-)

Errr... ummm... beta particles, I meant beta particles.

I guess that they must be very low energy beta particles, because if
they were able to penetrate the glass, they'd never have gone on the
market, even in the 70s.
