Main Page | See live article | Alphabetical index Radiography is the creation of radiographs, photographss made by exposing a photographic film or plate to X-rays. Since X-rays penetrate solid objects, but are slightly attenuated by them, the picture resulting from the exposure reveals the internal structure of the object. The most common use of radiography is in the medical field (where it is known as medical imaging), but veterinarians and engineers also use radiography.
