In steps in developing film first step is
1) Stirring the solution
2) Washing of film
3) Dip in developer
4) Dip in fixer
Radiology
Answer: 1
The first step in developing radiographic film is to ensure that the developing solution is well-mixed and at the correct temperature, which is achieved by stirring the solution (option 1). This ensures uniformity in the chemical reaction that will occur during the development process.
Washing the film (option 2) occurs after development to remove excess chemicals, while dipping in developer (option 3) is the actual step that follows stirring. Dipping in fixer (option 4) is the final step to stabilize the image.
