Which of the following lists the CBRN surveillance techniques?

• A. Periodic, Critical Node, Continuous, Area Array
• B. Periodic, Critical Node, Random, Area Array
• C. Periodic, Critical Node, Continuous, Random
• D. Periodic, Continuous, Area Array, Random

Answer: (A)

In CBRN surveillance, a robust approach combines timing, coverage, and focus on high-risk locations. Periodic monitoring provides regular data points to track changes and establish baselines. Continuous surveillance ensures immediate detection as events unfold, reducing the time to respond. Focusing on critical nodes targets locations where a release would have the most impact or where detection and containment are most challenging. An area array means deploying a network of sensors across a geographic area to achieve broad, spatial coverage and timely alerts across that space. Putting these elements together gives a surveillance plan that is systematic, timely, and spatially comprehensive. The other options fall short because they replace area-wide sensor coverage with random sampling or omit the emphasis on critical locations, which weakens reliability and rapid detection.
