IATA Training Practice Exam

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

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

Correct Answer:

It must not break or shatter under impact or bending and have at least 5 mm in one dimension

Explanation:

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.
