The shipping of radioactive materials in a metal drum is Type ____ packaging.

• A. C
• B. A
• C. B
• D. D

Answer: (B)

Dropping or rough handling is factored into how we choose packaging for radioactive materials, with different types providing different levels of protection. A metal drum used to ship radioactive material is Type A packaging. This level is designed for smaller quantities or materials with moderate hazard and is built to withstand normal transport and minor accident scenarios. It uses an inner containment plus absorbent and an outer sturdy container, like the drum, but it isn’t intended to endure the most severe accidents. More robust options exist for heavier or more dangerous shipments (Type B) and for certain air shipments (Type C). So, the metal drum fits Type A packaging because it’s suitable for lower-risk, routine transport.
