    Remember when folks wore watches with radioactive paint on them? Good times.

        Yeah, unfortunately most of the danger fell on the (usually female) factory workers who painted the radium on. Fun fact, we do absolutely still use radioactive shit to make watches glow today, it’s just much less dangerous and sealed in tiny vials. Also it’s a gas that won’t eventually flake and turn into super fine particulate, like the radium paints of yore.

      It was more a problem of licking the little brushes than wearing the teeny bit on the wrist.
