A controlled area is one that is

• A. restricted to access by nonradiation workers
• B. monitored by survey meters
• C. occupied by radiation workers
• D. occupied by the general population

Answer: (C)

A controlled area is designated because there is potential for occupational exposure to radiation, so entry is controlled and access is limited to trained, authorized personnel. The best answer fits because it reflects that the space is used for radiation work and is kept under supervision for safety. It isn’t defined simply by having survey meters, nor by restricting it to nonradiation workers or by being occupied by the general population. The defining idea is that radiation work occurs there and access is controlled for those who are trained to work with it.
