What can developer solution or cigarette ashes produce on the radiographs?

• A. fogging
• B. artifacts (LIGHT SPOTS)
• C. increased density
• D. improved contrast

Answer: (B)

Foreign material in the film processing path can show up as artifacts on radiographs. When foreign matter like cigarette ashes or contaminants in the developer interacts with the film, it blocks development in small, localized areas. That interference prevents the silver halide from developing normally, so those spots light up on the final image as light spots that don’t reflect any actual anatomy. This differs from fogging, which is a general, uniform darkening of the image caused by stray light or pervasive chemical issues, or from a true change in patient density, which would affect broader areas. So the familiar outcome is artifacts, appearing as light spots on the radiograph.
