What symbol identifies a radioactive material?

The trefoil symbol, which consists of three blades radiating from a central point, is specifically designed to identify radioactive materials. This symbol conveys a clear and recognized visual warning that the material may be hazardous due to its radiation emissions. The use of the trefoil symbol is standardized internationally, ensuring that individuals who encounter it can immediately recognize the potential dangers associated with exposure to radioactivity.

This symbol serves an important purpose in safety communication, alerting workers and the public to take necessary precautions when handling or being near radioactive materials. Its design makes it easily distinguishable from other hazard symbols used for different types of materials, reinforcing its unique association with the hazards presented by radioactive substances.
