Well that settles it for me. If my dad, Randy and Doug Hodder aren't worried about the old mantles, that's good enough for me. I'm exposed to so many chemicals and flavor oil aromas in my work that a little radiation can't hurt.

Dad worked at nuke plants for many years as a pipe support engineer. His first scientific calculator was an HP that cost almost $500, same thing today is like 10 bucks.
The reality is that with all of the time I spent working on nuclear subs, including a few sea trials while under reactor power, my dosimeter never registered anything higher than the background noise that we all get from the sun. When we were buying the house and had a home inspection done the sellers were quite surprised to find that their basement had high levels of radon. Knocked $1k off the sales price in order to have a system put in; has only cost the price of running a 60 watt bulb for the 13 years we've been here (cheap insurance). Another thing the home inspector said was to NOT use a charcoal filter in the whole house water filter (we have a drilled well); said it would concentrate any radiation and create a bigger hazard than if we just took the standard background exposure. So I just use the normal cotton wound filters.
Anyway, when I use the older mantles I won't go out of my way to suck in the fumes during initial burn and light off. But then again I wouldn't have been huffing them anyway, so all is good.
Where does the time go? I need to spend some time looking for a replacement globe.
