The amounts [if any] would be like americium in a smoke detector - traces of traces. Anything greater would run way more than $69. I am still looking for some old clock with radium painted dial - tritium gun sights go to half intensity in 11 years, but radium ones [glass encased] would last for centuries.
I was the RSO for a company, and people used to send me _things_ in the interoffice mail for disposal. They were bringing them in from home, and were careful to use a blank interoffice envelope. I resented it.
All kinds of stuff used to show up: The radium dial clocks, Corell Ware, OLD vaseline glass loaded with uranium (NOT like the recent stuff), WWII surplus lenses made with thorium flint glass that were BIG and hot, Coleman mantles, thoriated W TIG electrodes, etc..etc.
They say it is best not to orally moisten the tip of your brush when you refurb your sights.
How odd that you would mention that, GSlob! There was a story about two years ago about a High-School kid who got his hands on an old bottle of Radium paint, found inside an old clock. The story would have ended there, with any ordinary kid just painting things that glowed in the dark.
But this 13 year old senior was building a replica of an enrichment device as a science project, and decided to see if he could actually do it!
The details I remember are sketchy, but when the Haz-Mat people were done, the kid had a full-boat college scholarship, and his parents needed a new car and garage! Seems the re-rod in the floor was radioactive too.
I'll see if I can find that story and reference it for you. I would have kept it ... and I now realize that it was more like five years ago. Bookmarked - see ya later. Stay well..................FRegards
