Nuclear powered Round Fridge Magnet


Nuclear Powered Round Fridge Magnet

The radiation warning symbol should not be confused with the civil defense symbol designed to identify fallout shelters. 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. A design which is supposed to represent activity radiating from an atom. The first signs printed at Berkeley had a magenta symbol on a blue background. Blue was not supposed to be used on warning signs, and it faded, especially outdoors. The use of yellow was standardized in early 1948. All sorts of variations on the Berkeley design were suggested and implemented during the 1940s and early 1950s. Especially common were signs that incorporated straight or wavy arrows between, or inside, the propeller blades. By the late 50s, ANSI standards and federal regulations had codified the version of the warning sign used today. Present regulations also permit the use of black as a substitute for magenta. In fact, black on yellow is the most common color combination outside of the U.S.

Perfect for decorating your fridge, toolbox, desk or any where you'll like, this fridge magnet will stick on metal, anywhere you feel you deserve a special decoration spot. The colors contrast beautifully, this is the ideal gift to add style, even in the middle of the kitchen.
