ISO 21482
Technical standard for radiation warning symbols
ISO 21482
ISO 21482 is a technical standard that specifies the design and usage of a "supplemental radiation warning symbol", a warning symbol. It is intended to warn people of the dangers of radiation hazards posed by sealed sources, and encourage the viewer to get away from the source. The symbol's design was the result of a joint project between the International Atomic Energy Agency (IAEA) and International Organization for Standardization (ISO) in the early 2000s. The symbol was formally revealed to the public by the IAEA on 15 February 2007.
