Radioactive Warning Symbol - Universal Hazard Sign for Ionizing Radiation #191479 (License: Personal Use)

This image displays the standard ISO 361 radiation warning symbol: a bright yellow circle with three black equilateral triangles spaced at 120-degree intervals around a central black circle, forming a trefoil pattern. The high-contrast design ensures visibility and immediate recognition, critical for hazard communication in nuclear energy, medical radiology, research labs, and hazardous material transport. It was first introduced by the United States in 1946 and later standardized by the IAEA and ISO.

This image is typically used on safety signage, educational materials, regulatory documentation, and digital interfaces related to nuclear safety, radiation protection, or hazardous material handling. It matches user intent for identifying, understanding, or complying with radiation safety protocols.
