Radioactive Warning Symbol - Universal Hazard Sign for Ionizing Radiation #2216056 (License: Personal Use)

This image displays the standard ISO 361 radiation warning symbol: a bright yellow circle with three magenta blades arranged in a trefoil pattern around a central magenta circle. Designed in 1946 at the University of California, Berkeley, it conveys immediate danger from ionizing radiation and is mandated on containers, equipment, and facilities handling radioactive materials. Its high-contrast color scheme ensures visibility and recognition across languages and cultures.

Used on signage, packaging, and safety documentation for nuclear facilities, medical radiology departments, industrial radiography, and transport of radioactive substances. Matches user intent for hazard identification, safety training, regulatory compliance, or educational content about radiation risks.
