Which statement describes water with tritium concentration up to 0.8 TBq/L?

• A. Water with tritium concentration up to 0.8 TBq/L
• B. LSA-2
• C. Surface Contaminated Object
• D. Fissile Material

Answer: (A)

Understanding how a sample is described helps you see why this option fits. When water contains tritium, the description used is just the concentration in the water. Saying “water with tritium concentration up to 0.8 TBq/L” directly describes the material itself. The other options refer to broad categories or different kinds of materials: LSA-2 is a classification for low specific activity materials (typically solids), a Surface Contaminated Object refers to an object with removable surface contamination, and Fissile Material is something that can sustain a nuclear chain reaction. None of those describe the water sample in terms of its tritium concentration, so the straightforward description of the water is the appropriate choice.
