Radioactive Symbol - International Ionizing Radiation Warning Sign #228559 (License: Personal Use)

This image displays the standard ISO 361 radiation warning symbol: a central circle with three equally spaced magenta blades radiating outward at 60-degree angles, set against a white background and enclosed in a black border. Adopted globally since 1946 and standardized by the IAEA and ISO, it alerts personnel and the public to the presence of radioactive substances or ionizing radiation sources. The high-contrast magenta (or black in some variants) ensures visibility and immediate recognition in hazardous environments.

Used on containers, doors, equipment, and signage in nuclear facilities, medical imaging labs, research centers, and transport packaging to warn of radiation risks; matches user intent for safety education, regulatory compliance, or hazard identification.
