Who is the Radiation Protection Supervisor (RPS) in a dental practice?

• A. A patient
• B. A dental nurse
• C. A trained person in the practice responsible for ensuring compliance with radiation regulations
• D. The receptionist

Answer: (C)

The Radiation Protection Supervisor is a trained person in the practice who is formally responsible for ensuring compliance with radiation regulations. This role involves overseeing the use of X-ray equipment, making sure staff have appropriate training, enforcing local rules, arranging or performing quality assurance checks, monitoring patient doses, maintaining records, and liaising with the Radiation Protection Advisor as needed. A patient or a receptionist wouldn’t have the training or authority for this responsibility. A dental nurse could take on the role if they have the necessary training and formal appointment, but the essential point is that the person is a trained member of the practice charged with ensuring regulatory compliance.
