Which of the following is NOT a type of radioactive packaging?

The correct answer is that Type D is not a recognized category of radioactive packaging. In the context of the transportation of radioactive materials, the packaging types are specifically classified to ensure safety and compliance with regulations set by bodies such as the International Atomic Energy Agency (IAEA) and the Department of Transportation (DOT).

Type A packaging is designed for materials with higher levels of radioactivity and requires testing to confirm it can withstand potential accidents during transport. Type C packaging is intended for the transport of radioactive materials that may be exposed to air transport conditions, which includes higher levels of radiation and potential damage during transit. The term "Industrial" packaging typically refers to a form of packaging used for materials that do not exceed certain limits of radioactivity, allowing for the transport of lesser hazardous materials.

On the other hand, "Type D" packaging does not exist within the established classification for radioactive materials, which underscores that it does not fit into the recognized categorization needed for ensuring safe transport of these materials. Understanding these classifications is critical for hazardous materials technicians, as it guides appropriate handling and transportation protocols for various types of radioactive materials.
