Guides 161 and 162 pertain to what hazard, for which specific protection is listed?

• A. High-level radiation
• B. Medium-level radiation
• C. No radiation hazard
• D. Low level and low to moderate level radiation

Answer: (D)

The question tests your ability to map ERG guide numbers to the type and intensity of a hazard and the protective actions they call for. Guides 161 and 162 are the sections in the Emergency Response Guidebook that deal with radiological hazards, specifically for low-level and low-to-moderate radiation. That’s why the correct choice points to a low-level to moderate radiological situation.

This level of radiation calls for protective actions focused on minimising exposure—like maximizing distance from the source and limiting time exposed—with appropriate PPE as dictated by the situation. It’s not describing a high-level radiation incident that would require more extreme protection, and it’s not saying there is no radiation hazard.
