Which term is the coating on x-ray film that contains energy-sensitive crystals?

• A. Emulsion
• B. Digital Image
• C. Digitized
• D. Film Speed

Answer: (A)

In radiographic film, the coating that contains the energy-sensitive crystals is called the emulsion. This gelatin layer houses silver halide crystals that respond to X-ray exposure. When the film is exposed (often with help from an intensifying screen that converts X-rays to light), those crystals undergo a change that stores the image as a latent, invisible mark. During processing, the exposed crystals are developed into visible metallic silver, forming the radiographic image, while unexposed crystals are removed. The other terms refer to digital concepts or to the film’s overall sensitivity, not to the coating itself.
