In CBRN reconnaissance, to detect means to determine whether a hazard is present in the environment. It’s about answering yes or no: is there a CBRN threat here? This initial signal is what triggers protective actions and sets up further steps. It does not require or imply identifying what the hazard is, how much of it is present, or exactly where it lies. Those tasks—identifying the specific substance, quantifying its amount, and locating its precise position—come after detection, once the team knows a hazard exists. For example, a detector might beep or show a warning indicating a hazardous presence nearby; that confirms detection and prompts safety measures, while additional analysis would be needed to name the substance, estimate concentration, or map its location.
