Radiography

n. X-ray photography, photographic technique for imaging solid bodies with X-rays

Radiography is the use of certain types of electromagnetic radiation—usually ionizing—to view objects. The use of non-ionizing radiations (visible light and ultraviolet light) to view objects should be considered as a normal “optical” method (e.g., light microscopy). The modification of an object through the use of ionizing radiation is not radiography. Depending on the nature of the object and the intended outcome it can be radiotherapy, food irradiation, or radiation processing. [1]

Noun
1. the process of making a radiograph; producing an image on a radiosensitive surface by radiation other than visible light
(synonym) skiagraphy
(hypernym) photography
(hyponym) autoradiography
2. photography that uses other kinds of radiation than visible light
(hypernym) photography, picture taking
(hyponym) roentgenography, X-ray photography

Film records (radiographs) of internal structures of the body. Radiography is made possible by X-rays (or gamma rays) passing through the body to act on a specially sensitized film.

The making of a shadow image on photographic film by the action of ionizing radiation.
