Radiation Hazard Symbol - Universal Warning Sign for Ionizing Radiation #3893047 (License: Personal Use)

This image displays the standard ISO 361 radiation hazard symbol: a yellow circle with a black central dot and three equidistant black blades forming a trefoil pattern. Designed in 1946 at UC Berkeley, it signifies the presence of ionizing radiation and is mandated by regulatory bodies like the IAEA and OSHA. The high-contrast color scheme ensures visibility and immediate recognition in hazardous environments.

Commonly used on containers, doors, equipment, and signage in nuclear facilities, medical imaging labs, research centers, and transport vehicles carrying radioactive substances. Matches user intent for safety education, regulatory compliance, or hazard identification resources.
