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

This image displays the standard ISO 361 radiation warning symbol: a bright yellow equilateral triangle with a thick black border, enclosing a black trefoil (three-bladed propeller) centered on a circle. The design ensures high visibility and immediate recognition, critical for preventing accidental exposure in labs, nuclear facilities, medical imaging centers, and transport contexts. Its standardized form is mandated by IAEA and OSHA guidelines worldwide.

Used on containers, doors, equipment, and signage where radioactive substances or ionizing radiation sources are present. Matches user intent for safety education, regulatory compliance documentation, emergency response training, or scientific communication about radiation hazards.
