What is the THAAD radar personnel-denied occupancy zone?

• A. 100 meters
• B. 200 meters
• C. 50 meters
• D. 300 meters

Answer: (A)

The key idea is that a radar system like THAAD creates a high-power RF field, so there must be a safety buffer where personnel are not allowed to occupy during operation. This personnel-denied occupancy zone protects people from RF exposure and from any potential beam mispointing or reflections near the antenna. For THAAD, that protective radius is 100 meters. This distance provides a conservative safety margin to keep exposure within occupational limits while still allowing the system to operate effectively. A smaller distance would risk unsafe exposure levels, while a larger one would unduly restrict access and hinder maintenance or movement around the site.
