Radiation Hazard Symbol - Universal Warning Sign for Ionizing Radiation #2216210 (License: Personal Use)

This image shows the classic radiation hazard symbol (trefoil), consisting of three black blades arranged symmetrically around a central circle, enclosed within a black-outlined equilateral triangle on a bright yellow background. The high-contrast design ensures maximum visibility and immediate recognition in safety-critical environments such as nuclear facilities, medical imaging labs, and industrial radiography sites.

Used on signage, equipment labels, and safety documentation to alert personnel and the public to the presence of radioactive substances or radiation-emitting devices; matches user intent for safety compliance, hazard identification, or educational reference.
