The privileging authority in fixed and nonfixed dental facilities is required to appoint a Radiation Safety Officer (RSO). The RSO is responsible for overseeing the use of radiation and ensuring that dental facilities comply with all relevant health and safety regulations. This individual makes sure that appropriate safety programs are in place, helps develop and maintain radiation safety protocols, conducts regular safety audits, and provides training to dental professionals on how to properly use X-ray equipment and how to protect themselves and their patients from unnecessary exposure.
