Which packaging is used for more highly radioactive shipments, including steel reinforced concrete casks, lead pipe, and heavy-gauge metal drums?

Which packaging is used for more highly radioactive shipments, including steel reinforced concrete casks, lead pipe, and heavy-gauge metal drums?

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

Answer: (D)

The main idea is matching packaging strength to the level of radioactivity being shipped. For highly radioactive materials, the strongest packaging is Type B. Type B packages are built to withstand severe accident conditions—like drops, crushes, punctures, and immersion—without releasing their contents. The examples you mentioned, such as steel reinforced concrete casks, lead-shielded containers, and heavy-gauge metal drums, are classic Type B designs because they provide substantial shielding and structural integrity to keep radiation contained even in serious transport incidents. By comparison, Type A packaging is intended for smaller quantities and normal transport conditions, Type C is aimed at certain high-activity air shipments with extra requirements, and Type D covers other specialized cases. This is why Type B is the correct choice for more highly radioactive shipments.
