In radiology facility terminology, an area outside restricted area but with access limited by the licensee is known as which area?

• A. Limited area
• B. Controlled area
• C. Uncontrolled area
• D. Declared area

Answer: (B)

In radiology facilities, how spaces are labeled hinges on who can enter and how exposure is controlled. A controlled area is any space where entry is restricted by the licensee for radiation protection purposes, but it isn’t the most tightly restricted zone. Since the area described is outside the restricted zone yet still has entry limited by the licensee, it fits the definition of a controlled area. This labeling helps ensure that staff entering the space have appropriate training and monitoring, while the general public isn’t exposed to unnecessary radiation. Unrestricted areas have no entry controls, and the term declared area is used in other contexts to designate dose planning zones, not the situation described.
