What happens if a radiographic image is placed in the fixer before the developer?

If a radiographic image is placed in the fixer before the developer, it will result in a completely blank image. The fixer is designed to remove unexposed silver halide crystals from the film, so without the development step, there will be no latent image to reveal. Essentially, the film will be washed and rendered unusable for diagnostic purposes. Proper processing order is crucial for obtaining a usable radiographic image.
