Who is authorized to provide clearance for visitors to enter radiologically controlled areas?

In the context of radiologically controlled areas, it is crucial to maintain strict access control to safeguard both personnel and the environment from potential radiation hazards. The clearance for visitors to enter these areas is specifically reserved for individuals who possess a thorough understanding of the safety protocols and the associated risks.

Authorized personnel are typically trained and certified professionals, such as radiation safety officers or designated supervisors, who have the expertise to evaluate the safety and compliance standards necessary for visitors. Their role includes ensuring that all safety measures are in place before granting access and that visitors are well informed about the necessary precautions. This ensures that only those who have been properly vetted and instructed on safety procedures can enter areas where exposure to radiation may occur.

Other choices do not possess the required authority or training to grant such access, which is critical in maintaining a safe working environment.
