An area, outside of a restricted area, access to which can be limited by the licensee for any reason is defined as?

• A. limited area
• B. controlled area
• C. uncontrolled area
• D. declared area

Answer: (B)

Access control categories in radiation safety distinguish how entry is managed to protect people from exposure. An area outside a restricted area where the licensee can limit access for any reason is called a controlled area. This designation lets the licensee set entry requirements, signage, and monitoring to keep occupational exposure as low as reasonably achievable, without the stricter controls of a restricted area. An unrestricted area has no such access restrictions, and a declared area isn’t the term used for this context.
