What is the correct sequence of operations during radiograph processing?

The correct sequence of operations during radiograph processing begins with the developer, which plays a crucial role in converting exposed silver crystals into black metallic silver. This process creates the visible image on the radiograph. Once this development step is complete, the fixer is applied to the film. The fixer's primary function is to dissolve unexposed silver crystals that were not affected during the development process. By removing these unexposed crystals, the fixer ensures that the final image is stable and will not change or deteriorate when exposed to light.

Understanding this sequence is essential for anyone involved in radiography, as it highlights how the interactions between the developer and fixer lead to the formation of a clear and permanent image.
