Which description defines a radiologically controlled area (RCA)?

Which description defines a radiologically controlled area (RCA)?

• A. An area designated by RP in which additional controls are prescribed due to increased risk from exposure to radiation or radioactive material
• B. An area where no radiation is present
• C. An area for general public access
• D. An area with only administrative controls

Answer: (A)

A radiologically controlled area is an area designated by Radiation Protection where there is potential radiation exposure, so extra controls are put in place to keep dose and contamination under control. This means radiation or radioactive material may be present, and access is restricted with specific measures (training, authorized entry, monitoring, shielding, signage, and other controls) to reduce exposure risk. The description that matches this is the one stating it is designated by RP and that additional controls are prescribed due to increased risk from exposure to radiation or radioactive material. The other options describe areas with no radiation, areas open to the general public, or areas relying on only administrative controls, none of which fully capture the need for both designation and added controls.
