Oh this did make me remember the story about the "Radium Girls" painting clock dials. Do a DDG search for articles & joo tube to watch some videos. Poor broads got fucked up and over by that shit. I think their is also a movie about it called... Radium Girls. Another somewhat related story to the girls is "The Radioactive Boy Scout". Again, some quick interwebs searching will tell you that story, hekken wild shit.
