X-ray Examinations

X-rays account for 5 percent of total radiation exposure.

X-rays from an x-ray machine pass through the area of the patient's body being examined and are then detected with film. By far, x-rays account for most of the exposures from medical uses of radiation.

The parts of the body most often x-rayed are the teeth, chest, and limbs, each accounting for about a quarter of the total number of examinations.
