Distance is key to providing protection during fluoroscopy,because radiation exposure follows the inverse square law.(e.g.,the exposure at 2 m from the source will be only one-fourth as much as the exposure at 1 m distance.)When positioning the patient relative to the fluoroscopy image intensifier/C-arm,the patient should be placed as far away from the _______________ and as close to the __________as possible for optimal image quality and minimum radiation dose to the patient's body.
A) fluoroscope; lead shield
B) image intensifier; X-ray tube
C) X-ray tube; image intensifier
D) beam; radiologist
