Which packaging is described as used for low-level radiation shipments with an inner vessel of glass, plastics or metal and an outer container of plastic, rubber or vermiculite?

Which packaging is described as used for low-level radiation shipments with an inner vessel of glass, plastics or metal and an outer container of plastic, rubber or vermiculite?

• A. Type A
• B. Type B
• C. Type C
• D. DOT 407

Answer: (D)

This describes Type A packaging for radioactive materials. Type A is used for shipments of low-level radioactivity and is built with an inner vessel (made of glass, plastic, or metal) that holds the material, surrounded by an outer container that can be plastic, rubber, or an insulating/absorbent material such as vermiculite. The outer layer provides protection against leaks and helps absorb any minor leaks or shocks during transport, while the inner vessel remains leak-tight under normal conditions. Higher levels of radioactivity require Type B or Type C packaging, which are much more robust and undergo stricter performance testing. DOT 407, on the other hand, is a designation for packaging used for flammable liquids, not radioactive materials, so it doesn’t fit this scenario.
