What equipment is needed for x-ray radiography

It is not clear whether you are referring to medical or industrial radiography. But both need two parts of the equipment, namely, the source of radiation and the receiving part.

The two parts of a medical X-ray are the medical radiograph and the film (or in the case of DR, the IP image board and IP reader).

In the case of industrial flaw detection, the two parts are the flaw detector and the film.

If you go further, the equipment needed is a viewing light to see the film and a washer to develop the film.

If you go further, you will need a viewing light for the film and a film washer.
