I once had the pleasure of seeing Terry Pratchett speak, at the first Penguicon, near Detroit, MI. (Somewhen between 2006 and 2009, I think)

He told us, among other things, of working at a facility where they had to wear some sort of dosimeter, and were not allowed to leave the base without treatment if the card turned black, or something like that.

Then he mentioned one of the workers who turned up too hot to get IN to the base.

Turned out, he'd acquired some old aircraft instruments that used radium paint for nighttime visibility, and had been messing around with them.

Fun times!

Wow, that's a great story. Way too young...
