Which term is a recognized category of radioactive material characteristics?

• A. Fissile
• B. Low Specific Activity Material (LSA)
• C. Radioactive Material
• D. Special Form

Answer: (D)

Special Form is the term used to describe how the radioactive material is presented for transport. It refers to a solid, hermetically sealed form that is designed to not disperse its contents if the outer packaging is damaged. This specific presentation is a formal category in transport regulations, with defined criteria and testing, which is why it’s recognized as a distinct material characteristic. The other terms describe different aspects: fissile relates to the material’s ability to sustain a nuclear chain reaction and governs criticality safety, not the transport form; Low Specific Activity Material (LSA) is a separate classification about activity per mass and how that affects packaging requirements; and Radioactive Material is a broad umbrella term, not a specific form category. Therefore, Special Form best fits the idea of a recognized category of radioactive material characteristics used in transport regulation.
