Radioactive Warning Symbol - Universal Radiation Hazard Sign #75970 (License: Personal Use)

This image shows the internationally standardized ionizing radiation warning symbol, featuring a black trefoil (three-bladed propeller) centered on a yellow equilateral triangle with a thick black border. Adopted by the IAEA and ISO, it signals the presence of potentially hazardous ionizing radiation sources. The high-contrast design ensures visibility and immediate recognition in safety-critical environments.

Used on signage, packaging, and equipment in nuclear facilities, medical radiology departments, laboratories, and transport containers to alert personnel and the public to radiation risks. Matches user intent for safety education, regulatory compliance, or hazard identification resources.
