Radiation Hazard Symbol - Universal Warning Sign for Ionizing Radiation #3821476 (License: Personal Use)

The image displays the internationally recognized radiation hazard symbol (trefoil), consisting of a black three-bladed propeller-like design centered in a yellow equilateral triangle with a black border. Adopted in 1946 at the University of California, Berkeley, it signifies the presence of radioactive materials or ionizing radiation fields requiring caution and protective measures. Its high-contrast color scheme ensures visibility and immediate recognition across languages and cultures.

Used in nuclear facilities, medical imaging departments, laboratories, transport containers, and emergency response signage; this image serves users seeking safety information, regulatory compliance details, or educational content about radiation risks.
