Packaging used for transport with extremely low levels of radioactivity that present no risk to the public or environment is:

• A. Excepted
• B. Concrete Box
• C. Industrial
• D. Type B

Answer: (A)

When radioactivity is extremely low and presents no risk to people or the environment, the shipment is handled with excepted packaging. This category is designed for materials whose activity falls so far below regulatory thresholds that the hazard is negligible, so the packaging can be very simple and is largely exempt from the standard radiological packaging requirements. The focus is on safety through minimal risk, rather than on heavy shielding or extensive testing.

In contrast, higher-activity materials require more robust options like Type A or Type B packaging, which involve tested designs and shielding for containment. Type C is used for certain air shipments with even greater hazard. Industrial packaging sits between these, used for low-activity materials that still need some controls but not the full Type A/B requirements.
