Radioactive Warning Sign - Universal Symbol for Ionizing Radiation Hazard #5604 (License: Personal Use)

This image shows the standard ISO 361 radiation warning symbol: a yellow equilateral triangle with a thick black border, containing a black trefoil (three-bladed propeller) centered on a circle. The design is standardized by the IAEA and used globally to denote areas, materials, or devices emitting ionizing radiation that may pose health risks. Its high-contrast color scheme ensures visibility and immediate recognition in emergency or industrial settings.

This image is commonly used in safety manuals, nuclear facility signage, educational content about radiation, regulatory compliance guides, and emergency response training. It matches user intent for identifying hazards, understanding safety symbols, or preparing safety documentation.
