Which description accurately defines the physical requirements of Special Form radioactive material?

• A. It must be able to break under impact
• B. It must be dispersible in water
• C. It must not break or shatter under impact or bending and have at least 5 mm in one dimension
• D. It must be a liquid solution

Answer: (C)

Special Form material is defined by its ability to stay intact and not release its contents during transport, even under rough conditions. To achieve that, it must be a solid piece that does not break or shatter when subjected to impact or bending, and it must meet a minimum size requirement of 5 mm in at least one dimension. This combination ensures the material remains a discrete, non-dispersible unit rather than a fragile or dispersible substance. The other descriptions contradict this safety intent: breaking under impact would risk releasing material, dispersibility in water would enable spread, and being a liquid solution does not meet the solid encapsulated form required for Special Form.
