Which body regulates the transportation of radioactive materials?

The regulation of the transportation of radioactive materials is primarily the responsibility of the United States Department of Transportation (USDOT). This agency has established regulations to ensure the safe and secure transport of hazardous materials, including radioactive substances. The USDOT sets standards for packaging, labeling, and documentation, which are crucial for mitigating risks associated with the transportation of these materials.

While other organizations play important roles in related areas—such as the Environmental Protection Agency (EPA), which focuses on the environmental impact and safety of hazardous substances, and the Nuclear Regulatory Commission (NRC), which oversees the overall regulation of nuclear materials including their use, the actual logistics and safety of transportation fall under the jurisdiction of the USDOT. Additionally, the Occupational Safety and Health Administration (OSHA) is concerned with worker safety rather than the specifics of transportation regulations for radioactive materials.
