Ispitivanje pomoću Rendgenovih zrakova; naročito: izrađivanje fotografskih slika (radiograma) pomoću Rendgenovog aparata. (lat.-grč.)
1. Photography that uses other kinds of radiation than visible light.
2. The process of making a radiograph; producing an image on a radiosensitive surface by radiation other than visible light; SYN. skiagraphy.
Making and study of X-ray photographs. Branch of science concerned with the use of radiation (particularly X-rays) to produce images on photographic film or fluorescent screens. X-rays penetrate matter according to its nature, density, and thickness. In doing so they can cast shadows on photographic film, producing a radiograph. Radiography is widely used in medicine for examining bones and tissues and in industry for examining solid materials; for example, to check welded seams in pipelines
Nondestructive method of internal examination in which metal objects are exposed to a beam of X-ray or gamma radiation; differences in thickness, density, or absorption caused by internal defects or inclusions are apparent in the shadow image produced on a fluorescent screen or photographic film placed behind the object.
