Which of the following is the correct sequence of dark room processing of a radiograph
1) Rinsing, fixing, developing, washing and drying
2) Developing, rinsing, fixing, washing and drying
3) Washing, fixing, developing, drying and rinsing
4) None of the above
Radiology
Answer: 2
The traditional darkroom processing sequence for radiographs is as follows:
Developing: This step involves immersing the film in a
developing solution to reveal the latent image captured on the film.
Rinsing: This step is crucial to halt the development
process, preventing further exposure to the chemical in the developer.
Fixing: The film is then placed in the fixer solution
to stabilize the image and make it insensitive to light.
Washing: The film must be washed to remove any residual
chemicals before drying.
Drying: Finally, the film is dried for use.
