During fluoroscopic procedures, which position best reduces operator exposure?

• A. Behind the image intensifier
• B. Behind the tube side
• C. In front of the patient
• D. Beside the patient

Answer: (A)

During fluoroscopy, most operator exposure comes from scatter radiation produced as the X-ray beam passes through the patient. Standing behind the image intensifier puts a strong barrier between you and that scatter, and places you away from the primary beam path, significantly reducing the dose you receive. Being on the tube side, in front of the patient, or beside the patient keeps you closer to the scatter or even toward the primary beam, which increases exposure. So, positioning yourself behind the image intensifier is the best way to minimize exposure.
