UNIVERSAL RADIATION SYMBOL

radiation symbol

An international symbol used to indicate radioactive sources, containers for radioactive materials, and areas where radioactive materials are stored and used. The presence of this symbol (a magenta or black propeller on a yellow background) on a sign denotes the need for caution to avoid contamination with or undue exposure to atomic radiation. The wording on the sign varies with the level of potential radiation in the area.
