Precautions while using X Rays
How do X rays produce an image
As the radiation penetrates the body, it is absorbed in varying amounts by different body tissues. Bones absorb maximum X ray radiation while lung tissue absorbs very little, allowing most of the X ray beam to pass through the lung. Thus when one does the Chest X ray the lungs appear black and bone appear white in color.
