Which packaging type is indicated by the words 'TYPE C' and includes a trefoil symbol as shown?

• A. Type A Packaging
• B. Type C Packaging
• C. Type B Packaging
• D. Radioactive Overpack

Answer: (B)

Seeing the words TYPE C together with the trefoil symbol tells you this packaging is designed for air transport of radioactive materials. The Type C designation is specific to packaging certified for air shipments, with the necessary containment, shielding, and impact protection that such transport requires. The trefoil marks the presence of radioactivity, confirming the material inside is radioactive. This makes it the correct choice because it matches both the label and the intended mode of transport. Other options refer to different packaging categories or to generic radioactive containment: Type A is for lower-hazard quantities not typically used for air transport; Type B covers higher activity but not specifically designated for air shipment in the same way; a radioactive overpack is just an outer container and not a standalone Type C packaging.
