Which of the following is provided as an example of a lower tier area?

• A. Flight line
• B. Parks
• C. Recreational areas
• D. Hospitals

Answer: (B)

Lower tier areas are spaces where exposure to non-ionizing radiation is low and access is broadly unrestricted, typically public outdoor environments with few or no nearby high-power sources. Parks fit this well because they are open, public areas with minimal exposure to strong RF sources and no mandatory access restrictions. In contrast, a flight line involves proximity to high-power radar and transmitter equipment, which increases exposure, and hospitals contain sensitive equipment and controlled zones, making them higher tier. Recreational areas is a broader category, but parks are the clearest example of a lower tier setting.
