![]() The three-bladed radiation warning symbol, as we currently know it, was "doodled" out at the University of California Radiation Laboratory in Berkeley sometime in 1946 by a small group of people. The Office of Civil Defense originally intended fallout shelters to use the radiation warning symbol with the circle in the center and the three blades, but this idea was rejected because a fallout shelter represents safety whereas the radiation warning symbol represents a hazard. The general form is very similar to the above however there is no central circle. The civil defense symbol for a fallout shelter consists of a circle divided into six sections, three black and three yellow. For more information about the latter, view the collection item Civil Defense Fallout Shelter Sign. The radiation warning symbol should not be confused with the civil defense symbol designed to identify fallout shelters.
