What task involves the act of locating CBRN hazards?

The act of locating CBRN hazards is best described as detection. Detection involves the use of various tools and techniques to find or identify the presence of chemical, biological, radiological, or nuclear hazards in a given area. This task is crucial in reconnaissance operations because it allows for the early identification of potential threats, enabling appropriate measures to be taken to mitigate risks to personnel and the environment.

Monitoring typically refers to the continuous observation of environmental conditions, which may include overseeing CBRN hazards, but does not specifically entail the active searching or locating of such hazards. Identifying is closely related to detection but usually follows the detection phase, aiming to confirm the type and nature of the hazard found. Assessing involves evaluating the impact or consequences of detected hazards, thus taking the process a step further after detection has already occurred.
