@adamd I have a sticker on my satchel, which I got from Malki! (the Wondermark guy) at the World Science Fiction Convention in Spokane (or Mordor), with the radiation trefoil & the legend “Keep Clear! I don’t think this thing is nuclear-powered, but I can’t rule it out.” Haven’t had a problem taking through Airport Stupidity yet.
@adamd Also, this page (from the Oak Ridge Associated Universities) has the canonical More Than You Ever Wanted To Know :
