The iconic radiation symbol is bad design.
It was doodled in 1946 to look a bit like an atom. The problem is it doesn't seem very threatening to folks who encounter it without knowing the meaning, which has actually killed people. There is an alternate symbol & scarier warnings. pic.twitter.com/jHSCDTFdf8

The alternate symbol: to go to the fun and cool Halloween party, run this way!
