Who may be present in the room during radiographic exposure?
In the case of a single-chair room, persons must not be present in the room during a radiographic exposure unless their presence is necessary for conduct of the examinations. Persons present must be located behind a shield allowing a view of the patient and the “exposure on” indicator, or wearing protective apron, or at least 2 m from the source of scattered radiation, i.e. the patients head, and not in line with the primary beam [RPS 10]. In the case of the multi-chair room, there should be adequate shielding between the chairs.
