List the standard processing steps for film radiographs and the purpose of each step.

• A. Develop (reduces exposed silver halide to metallic silver producing a visible image), Rinse (stops development), Fixer (removes unexposed silver halide and hardens the emulsion), Wash (removes chemicals), Dry.
• B. Rinse, Develop, Dry, Wash
• C. Develop, Fixer, Rinse, Dry, Wash
• D. Dry, Wash, Develop, Rinse, Fixer

Answer: (A)

Film radiograph processing is about turning a latent image into a permanent, visible one through a sequence of chemical steps. First, development uses a developing agent to reduce the exposed silver halide crystals in the emulsion to metallic silver. This creates the dark areas that form the image, while unexposed crystals stay mostly untouched, so they don’t create image density. A rinse follows to wash away most of the developer and to halt further development, helping to prevent overdevelopment and controlling image contrast. Next comes fixation, which removes the unexposed silver halide crystals from the emulsion and hardens the gelatin. This step locks the image in place and makes it insensitive to light, so the film won’t darken when exposed to ambient light. Washing then removes all residual fixer and developer chemicals from the film, preventing chemical reactions that could stain or damage the emulsion over time and ensuring long-term stability. Finally, drying eliminates moisture so the film can be handled, viewed, and stored without smearing or sticking.
