Radiology Practice Test

Are Developer and fixer solutions sterilizing agents?

1. Yes

2. No

3. Sometimes

4. Depends on the type of solution

The correct answer is: No

The designation of developer and fixer solutions in radiography as non-sterilizing agents is accurate. These solutions are specifically formulated for the chemical processing of radiographic films, where the developer works to reduce exposed silver halide crystals to metallic silver, while the fixer removes unexposed crystals, ensuring that the image is preserved. Both developer and fixer solutions do not possess sterilizing properties, as their primary function is not to eliminate all forms of microbial life. Instead, they are designed to facilitate the imaging process. Therefore, the conclusion that these solutions do not serve as sterilizing agents is well-supported, as their roles are fundamentally tied to film development rather than disinfection or sterilization in a clinical or surgical context.
