What regulatory document provides guidelines for the transportation of radioactive materials?

The correct answer is Title 49 of the Code of Federal Regulations (CFR), which outlines the regulations specific to the transportation of hazardous materials, including radioactive substances. This set of regulations is established by the Department of Transportation in the United States and provides detailed guidelines on packaging, labeling, and proper transportation procedures to ensure safety and compliance during the transport of radioactive materials.

Understanding this framework is essential for anyone involved with the transportation of radioactive materials, as it addresses technical requirements and safety measures necessary to protect public health and the environment while facilitating the safe movement of such materials.
