Shipping radioactive materials in a metal drum is classified as which type of packaging?

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

Answer: (A)

Shipping radioactive materials in a metal drum is classified as Type A packaging because Type A packaging is designed for the transport of radioactive materials that do not exceed specific activity limits. This type of packaging must be capable of withstanding normal shipping conditions such as impact and vibration without releasing any radioactive material.

Type A packaging typically includes strong materials, like metal drums, which provide sufficient shielding and containment for low-level radioactive wastes or limited quantities of more radioactive contents. It ensures safety for handlers, the public, and the environment during transportation.

As for the other types of packaging, Type B is intended for larger quantities of radioactive materials that pose a greater risk and require more robust containment methods, suitable for severe accident conditions; Type C is designed for air transport of high-activity materials, necessitating even stricter performance standards; and Type D is not commonly recognized in the classification of HAZMAT transport packaging. Therefore, Type A is the correct classification for shipping radioactive materials in a metal drum under standard conditions.
