What type of packaging is used for high activity, radioactive materials, transported by aircraft?

• A. Type A
• B. Type B
• C. Type D
• D. Type C

Answer: (D)

High-activity radioactive materials shipped by air require the most robust containment, designed to survive the stresses of flight and potential accidents. Type C packaging is specifically developed for air transport of these highly active or sensitive materials, with stringent testing and certification to ensure containment, shielding, and safety during flight.

Type A packaging is intended for lower activity and simpler forms, with lighter testing. Type B packaging can handle substantial activity and is robust, but it isn’t designated specifically for the flight-only, extreme-conditions requirements that Type C packaging provides. Type D isn’t a standard category for these classifications.
