Radioactive Warning Symbol - International Ionizing Radiation Hazard Sign #1207221 (License: Personal Use)

This image displays the standard ISO 361 radiation warning symbol: a bright yellow equilateral triangle with a thick black border, containing a central black circle and three black扇-shaped blades spaced at 120 degrees. Designed in 1946 at the University of California, Berkeley, it is universally recognized under IAEA and OSHA standards to denote areas, materials, or devices emitting ionizing radiation. The high-contrast color scheme ensures visibility and immediate recognition even from a distance.

Used on containers, doors, equipment, and signage in nuclear facilities, medical imaging labs, research centers, and transport vehicles carrying radioactive materials; serves to warn personnel and the public of radiation hazards and support regulatory compliance (e.g., OSHA 1910.1096, IAEA Safety Standards).
