“New international radiation symbol.” was penned precisely on 21 February, 2007 01:38 PM, which happened to be a Wednesday. but you know what? dullneon.com's random notes has now moved to a new location.

This new symbol was “developed by human factor experts, graphic artists, and radiation protection experts, was tested by the Gallup Institute on a total of 1 650 individuals in Brazil, Mexico, Morocco, Kenya, Saudi Arabia, China, India, Thailand, Poland, Ukraine and the United States”.
If they had asked me, I’d have said it looked like it says “Run before the triangular sperm thing from the fan hits your head”.
