Although Tritium does produce ionizing (beta IIRC) radiation, it's pretty weak compared to most radioactive materials. Typically you ingest it as tritiated water, but you can also breath it. As long as it's not in your body pinging around in your tissues, you should be relatively safe. Don't go breaking it open and eating the stuff even if it leaves your body in about a month... <img src="/images/graemlins/smile.gif" alt="" /> If it does break open, handle it with chem gloves and dispose of properly. For the most part don't handle it, breath it or ingest it, and it shouldn't pose any problems in it's sealed tube.

I purchased some thru eBay from the dealer Raven-Tech I have also purchased some from him outside of eBay. I receive them in 4 days from the U.K. (Not bad huh). Everyone who sees them wants them. My girlfriend wears them out to the club and gets alot of attention. Boring me just uses them on my key chain and EDC kit like Sgt Mike.

BTW...the 3 main uses for tritium in the U.S. is (was?) in watches, gun sights and EXIT signs.

Dread

Ive also purchased from Raven-Tech and can recommend them.
