Which situation prompts continuous monitoring to begin?

The initiation of continuous monitoring is critical following a confirmed nuclear detonation in the area. This event creates an environment laden with potential radioactive contaminants, rendering immediate and sustained monitoring essential to evaluate the extent of the hazard and potential exposure to personnel. The confirmation of a nuclear detonation indicates the release of radiological materials, necessitating a proactive approach to ensure safety and to inform decision-making processes. Continuous monitoring allows for real-time data collection, helping to assess radiation levels and guide operational responses effectively.

On the other hand, periodic monitoring alone may suggest safety but does not account for unexpected hazards that could arise from a nuclear blast. Completing a mission might indicate a need for assessment, but it does not inherently trigger the need for continuous observation. Similarly, being located far from headquarters could complicate communication or support logistics, but does not inherently prompt continuous monitoring; it’s the presence of a confirmed nuclear threat that drives that urgency.
