What does the washing step accomplish?

• A. Removes fixer
• B. Removes unexposed crystals
• C. Develops latent image
• D. Dries the film

Answer: (D)

The washing step is meant to remove fixer from the film and rinse away residual chemicals and byproducts left in the emulsion after fixation. This prevents ongoing chemical activity that could degrade the image, cause discoloration, or reduce archival stability. Development happens during the developing step, and drying occurs in a separate final step after washing. Washing does not remove unexposed crystals; those grains stay in the emulsion, while the fixer is what needs to be washed away to stabilize the radiographic image.
