Radiation Hazard Symbol - Universal Warning Sign for Ionizing Radiation #228677 (License: Personal Use)

This image displays the internationally standardized radiation hazard symbol, known as the trefoil, consisting of three black curved blades spaced at 120-degree intervals around a central circle, set against a vivid yellow background. Designed in 1946 at the University of California, Berkeley, it is used to mark radioactive materials, equipment, or areas where ionizing radiation poses a risk to health. Its high-contrast design ensures immediate recognition and compliance with safety regulations worldwide.

This image is typically used on safety signage, educational materials, regulatory documentation, and emergency response guides to indicate radiation hazards. It matches user intent for identifying, understanding, or communicating radiation risks in industrial, medical, or scientific contexts.
