Movement contamination from tritium subs?

[Pure_class]

Any risk in working with a movement that may have once been in a tritium dialed sub? Say 1520 or 3135 etc. I know working with the dials one needs to be careful or should leave to a professional. Just wondering if any small particles were to have ever come in contact with the movement during disassembly if it could pose any health issues. Once a movement is serviced and cleaned would it rid any possible issue of this anyways?

Minutia....I wouldn't give it a second thought.

Are you sure you're not thinking of radium dials? The hazard associated with tritium dials is truly miniscule.

I know of the older radium dials were horrible to work with and still are, I actually did think Tritium is also dangerous to work with, but didn't realize it doesn't pose much of a threat. I assume because most tritium is well past the 12.5 years of half life..

Tritium is an inhalation/ingestion hazard. You would need to find a lot of it and eat it for there to be any issue.

The Lume, itself, is not tritium. Tritium is a very small part that is mixed with the lume paint. It is more likely that you will stab yourself with a screwdriver while working on a watch than ingest any tritium.
