Which of the following is not a responsibility of the radiation safety officer?

The selection of scheduling patient appointments as the correct answer reveals an understanding of the role and responsibilities assigned to a radiation safety officer (RSO). The RSO primarily focuses on maintaining safety standards regarding radiation exposure within the clinical or dental setting. This includes making sure that all staff members are properly trained on radiation safety protocols, conducting regular checks and monitoring of radiation-emitting equipment to ensure it is functioning effectively and safely, and supervising compliance with established safety regulations to mitigate any potential risks.

In contrast, scheduling patient appointments falls outside the RSO's core responsibilities. Such administrative tasks are typically managed by front office staff or appointment coordinators who handle the logistics of patient flow rather than focusing on the technical and regulatory aspects of radiation safety. Therefore, this element does not align with the duties designated to the RSO, making it the correct choice.
