Press Release Summary: The idea for the current radiation warning symbol was developed in 1946 by a small team of scientists at the University of California Radiation Laboratory in Berkeley. Led by Nelson Garden, the head of the Health Chemistry Group at the Radiation Laboratory, the group produced an idea that they all agreed on. The symbol they designed was a small solid circle with what looks like three propeller blades equally spaced around the circle. The reason for their choice of symbol has remained a mystery over time. In a letter written in 1995 by Paul Frame, a doctor at Oak Ridge Institute for Science and Education, he describes his belief that the symbol takes after the Japanese battle flag, which has a circle representing the sun in the middle with rays radiating out from it, because, after all the radiation warning symbol came along within a couple of years of WWII.
Others believe that it is just a variation of the many symbols used to depict radiation before that time. Some of those early symbols were very similar to this three bladed design. One had a small circle in the center and then four lightning bolts surrounding it pointing out from the center much like the propellers. Others were just small lightning bolts in a circular formation. In a letter written in 1952, Nelson Garden did describe his first thought when his group produced the idea, "a design which was supposed to represent activity radiating from an atom," though it is still unknown if this is the true reason for its development.
Not only did the group of scientists have to think of an idea for this symbol that was not supposed to be similar to anything else, but they also had to come up with a color scheme, one that would stand out to everyone. Their original idea was a magenta symbol placed on a blue background. This received criticism because many believed that the blue would not be visible enough. However, Garden said in a letter he wrote in 1948, "The use of a blue background was selected because there is very little blue color used in most of the areas where radioactive work would be carried out." He then explained his reason for not using yellow, classic for a warning sign because of its easy visibility, "the very fact that . . . the high visibility yellow stands out most prominently has led to extensive use of this color and it is very common." Garden continued to press for the use of the blue background, but in 1948, majority of workers denied it, complaining that the blue faded out very quickly during the daytime and was not visible during the night.
The design was then taken to Oak Ridge National Lab where various color schemes were produced and tested in order to see which scheme would be the most visible at a distance of twenty feet. The color plan they finally decided on was keeping the circle and propellers magenta (with the option if making them black instead, standard for a warning sign), and changing the blue background to the classical yellow. In their tests the yellow background was clearly the most visible, ending the search for a radiation warning symbol . In the end, the workers who needed the warning symbol felt that it mattered much more to them to have their symbol be more visible as possible than to have it be an original color plan. Nelson Garden and his group created the perfect symbol. It was unmistakable; and with the help of the Oak Ridge National Lab, it was one that easily stood out to the many workers.
