What are the requirements for Type A packages?

Type A packages are specifically designed to safely contain and transport radioactive materials. The primary requirement for these packages is that they must be able to retain containment under transport conditions. This means that they should adequately protect both the contents from loss or release and the environment from contamination, even during normal transport scenarios, which might include physical shocks, vibrations, or temperature changes.

The focus on containment is critical because it ensures that any radioactive material remains securely enclosed, minimizing the risk of exposure to the public and the environment during transport. Regulations governing Type A packages mandate rigorous standards for structural integrity and performance tests to confirm their capability to withstand various conditions without leaking or breaking.

While packages must be marked as hazardous and may have specific labeling requirements, such as indicating the weight of the contents, the definitive characteristic that sets the requirements for Type A packages apart is their ability to retain containment and ensure safety during transportation. Fireproof and explosion-proof features are more aligned with other categories of packaging, particularly for materials that pose additional risks beyond radiation.
