English: The new supplementary ionizing radiation warning symbol launched on 15 February 2007 by the International Atomic Energy Agency (IAEA) and the International Organization for Standardization (ISO). Contains radiating waves, a skull and crossbones and a running person, on a red triangle.
The symbol is intended to be used inside equipment housings, as a warning to stop dismantling a device and get away from it. The symbol is not intended to be visible during normal use of the equipment. It is also not intended for use on building doors or walls, vehicles, or transportation containers.
