What is the correct order for processing analogue radiography?

• A. washing, drying, developing, fixing
• B. developing, fixing, washing and drying
• C. fixing, developing, washing, drying
• D. drying, washing, developing, fixing

Answer: (B)

The processing order for analogue radiography follows the sequence needed to turn a latent image into a stable, usable film. The film first enters the developer, which reduces exposed silver halide crystals to metallic silver, creating the visible image. Next, the fixer removes unexposed silver halide and fixes the image in place so it won’t continue to darken. After fixation, washing cleans away residual chemicals to prevent ongoing reaction and reduce artifacts. Finally, the film is dried so it can be handled and viewed without moisture affecting the image. If any step comes before its proper place (for example, fixing before developing or drying before washing), the image would not form correctly or could be damaged by residual chemicals.
