These people love to collect radioactive glass. Are they nuts?

Far be it from me to claim that someone is nuts because of what they collect.

I have full three display cases of Lego minifigures hanging on my wall. If you happen to want to hang out with radioactive glass in your display cases, who am I to judge?

I've hard of vaseline glass and knew it was also known as uranium glass because of the uranium oxide in the glass. I hadn't heard of it being called canary glass, though, and I was never quite sure of the radiation dosage that any collectors would be receiving.

Luckily, this article, from Collectors Weekly clears that right up.
