Which test is used to evaluate Special Form radioactive material?

• A. Impact test
• B. Bending test
• C. Leaching and volumetric assessment
• D. Heat test

Answer: (A)

The key idea here is that Special Form radioactive material must stay in one piece and not disperse if an accident occurs during transport. This is all about mechanical integrity under impact. The impact test directly checks how the material behaves when subjected to a sudden, high-energy shock—like a drop or collision—to see if it remains intact or fragments, which would risk dispersal. If the material survives the impact without breaking apart, it meets the requirement for Special Form.

The other tests don’t target this specific risk. A bending test looks at behavior under flexural stress, not the sudden shock of an accident. Leaching and volumetric assessment evaluates whether material could leach out into the environment, which is more relevant to liquids or porous forms than to a solid, intact form. A heat test simulates high temperatures, but it doesn't assess the risk of dispersal due to impact. Therefore, the impact test is the appropriate evaluation for Special Form material.
