Which area would require a higher level of monitoring due to radiation exposure?

Radiologically Controlled Areas are designated spaces where the potential for radiation exposure exists, necessitating a higher level of monitoring. These areas are specifically established to ensure that personnel and the public are protected from harmful levels of radiation. Due to the nature of activities conducted in these zones—such as handling radioactive materials or working with radiation-producing equipment—consistent and rigorous monitoring protocols are implemented to track radiation levels and ensure they remain within safe limits.

In contrast, unrestricted areas and public access areas typically have lower radiation levels and do not pose significant risks of exposure, thus requiring less stringent monitoring. Storage areas, while they may contain radioactive materials, may not always require the same level of continuous radiation surveillance as radiologically controlled areas unless they are actively accessed or used in operations. Therefore, the designation of Radiologically Controlled Areas reflects their critical need for thorough monitoring due to the inherent risks associated with potential radiation exposure.
