In unzoned areas, which statement is true about radioactive transport and contamination?

• A. Not allowed to transport radioactive materials
• B. Contains the highest contamination risk
• C. Radioactive material may be transported through. Expected to be free of contamination
• D. Plastic sheeting is required

Answer: (C)

In unzoned areas, moving radioactive material is allowed under proper regulatory controls, and the shipment is expected to remain free of contamination. This means packages and transport vessels are designed to prevent release or transfer of radioactivity, with cleanliness checks and decontamination procedures in place if any contamination is detected. The idea isn’t that unzoned areas are unsafe or off-limits, but that safe transport relies on containment, monitoring, and adherence to procedures so the material doesn’t contaminate surfaces or the environment. The other statements oversimplify the situation: transport is permitted with controls, contamination risk varies by source and handling, and plastic sheeting isn’t a universal requirement for all transports.
