What type of materials are typically transported in Type C radioactive containers?

Type C radioactive containers are specifically designed to transport materials that require a high level of safety due to their radioactive nature and potential hazards during air transportation. These containers are constructed to meet stringent design and performance standards mandated by regulations, particularly for air shipments, where the risk of accidents can be greater due to altitude changes, variations in pressure, and other factors unique to airborne transportation.

In the context of transporting radioactive materials, the primary focus is on ensuring that containment is maintained under a variety of conditions that may occur during air travel. The robust design of Type C containers helps prevent the release of radioactive materials, even in the event of an accident or incident during flight. Therefore, it is critical that the materials transported in such containers adhere to the specifications for safe transport defined by regulatory bodies.

While other options like solid waste, liquid food products, and compressed gases may require specialized containers for different reasons, they do not align with the specific protocols established for the handling and transport of radioactive materials intended for air travel.
