Another name for the hot zone is the ______.

• A. Exclusion zone
• B. Clean zone
• C. Restricted zone
• D. Safety zone

Answer: (A)

The hot zone is the area closest to the release where contamination and exposure are at their highest, and access is strictly controlled. The term exclusion zone captures this idea because it communicates that entry is off-limits to anyone not authorized and properly protected. A clean zone implies no contamination, which isn’t the center of the hazard; a restricted zone is a general access limit and doesn’t specifically indicate the highly contaminated core; a safety zone is too vague and doesn’t convey the need for exclusion. So, exclusion zone best matches the hot zone’s level of danger and access control.
