One of the great weaknesses from the Green side (my side) is the uninformed emotional response to risk. I have a camera lens that will make a geiger counter scream. My wife wears a beautiful Chinese medallion made of mercury.
Lots of thorium glass was used in the 50’s & 60’s. I used to own a couple like that but didn’t want to deal with the yellowing the radiation causes. Has your lens turned yellow?
