Which of the following is a CBRN reconnaissance task?

• A. Detect
• B. Measure
• C. Observe
• D. Analyze

Answer: (B)

Measuring is the act of determining the level, concentration, or dose rate of a CBRN hazard at a specific location. In reconnaissance, you need quantitative data to assess risk, compare against thresholds, and guide decisions about movement, isolation, or decontamination. Detecting signals the presence of a hazard, and observing gathers situational context, but neither gives the actual magnitude. Analyzing comes after collecting data to interpret results. Because the task asked for obtaining numeric information about the CBRN environment, measuring is the most direct and essential reconnaissance action.
