A diagram that explains the difference between the existing radiation warning symbol, the 'trefoil', or ISO 7010 - W003 - Radioactive material or ionizing radiation (The larger, yellow symbol), and ISO 21482's supplemental radiation warning symbol. (The smaller red symbol visible in panel 2.).
Panel 1: An individual is opening the housing of a piece of machinery containing a radioactive source, marked with a radiation trefoil symbol.
Panel 2: The individual running away, after opening up the housing, revealing a radioactive source, and the ISO 21482 safety symbol inside the machine, near the radioactive source (represented as a black rectangle with a white trefoil symbol.)
