Type B packaging for radioactive material is best described as

• A. A spherical plastic package used for small quantities
• B. Cylindrical or box-like cask packaging made of rigid metal designed to perform under hypothetical accident conditions
• C. A wooden crate with no shielding
• D. A simple fiberboard box with minimal protection

Answer: (B)

Type B packaging is the robust, containment-and-sh shielding solution used for higher-activity radioactive materials during transport. It must be capable of withstanding hypothetical accident conditions—like severe impacts, crush scenarios, external fires, and immersion—without releasing its contents. The design is typically a rigid metal cask, cylindrical or box-like, engineered to keep the material contained and to limit radiation exposure to people and the environment even in severe conditions.

The other descriptions describe far less protection: a simple spherical plastic package for small quantities or a wooden crate, or a basic fiberboard box with minimal protection, would not meet Type B standards because they lack the necessary containment, shielding, and accident-resistance features.
