This image displays the standard ISO 361 radiation warning symbol-a bright yellow equilateral triangle with a thick black border, containing a black trefoil (three-bladed propeller) centered on a circle. The design is standardized by the IAEA and used globally to denote the presence of ionizing radiation sources, including in nuclear facilities, medical imaging, and transport of radioactive substances.

Used on signage, equipment labels, packaging, and safety documentation to alert personnel and the public to radiation risks; matches user intent for hazard identification, safety training, regulatory compliance, or educational content.
