Radioactive Symbol - Universal Ionizing Radiation Warning Sign #3893045 (License: Personal Use)

This image displays the standard ISO 361 radiation warning symbol: a yellow circle with a black border, containing three magenta (or black) 60-degree sectors radiating from a central magenta circle. Designed in 1946 at the University of California, Berkeley, it signifies the presence of ionizing radiation sources such as nuclear materials, X-ray equipment, or contaminated zones. The high-contrast color scheme ensures visibility and immediate recognition under varied lighting conditions.

Commonly used on signage near nuclear facilities, medical imaging rooms, laboratories, transport containers for radioactive materials, and emergency response kits. Matches user intent for safety education, regulatory compliance, hazard identification, or technical documentation.
