=?DIN_66003?Q?International_use_of_radiation_symbol?=



We have a non-US partner in a project who wants to use the radiation
trefoil symbol, or "standard radiation symbol", to denote nonionizing
radiation hazards. Are there any international guidelines, IAEA or
otherwise, for the use of the trefoil symbol? Is it common practice in
other countries to use the trefoil for nonionizing radiation?
