Which HAZMAT class does radioactive materials fall under?

Radioactive materials are classified under Class 7 of the Hazardous Materials Transportation regulations. This classification specifically identifies the unique nature of radioactive materials, which emit ionizing radiation that can pose serious health risks to humans and the environment.

Class 7 covers substances that emit radiation, including both the materials themselves and their packaging under specific conditions. This classification is crucial for the safe handling, transportation, and disposal of radioactive materials, ensuring that responders are aware of potential hazards associated with exposure. The handling of these materials requires stringent safety measures to protect against radiation exposure, which is not applicable to the other hazard classes listed.
