An image produced on photosensitive film by exposing the film to radiation and then processing it is called what?

• A. Radiograph
• B. Radiation
• C. Photon
• D. Primary Beam

Answer: (A)

In radiography, the image that appears on photosensitive film after it has been exposed to X-ray radiation and processed is called a radiograph. The radiograph is the visible record of the internal structures based on how different tissues attenuate the X-ray beam and how that attenuation is captured by the film during developing and fixing.

Radiation refers to the energy emitted as X-rays, not a picture. A photon is the smallest unit of that energy—a particle of light, including X-rays. The primary beam is the initial X-ray radiation leaving the tube before it interacts with the patient. None of these create the image itself; the radiograph is the produced image after exposure and processing.
