Xray Processing Flashcards
What is the first step of the X-ray processing cycle?
Developer
What are the active developing agents on the developer solution?
Hydroquinone
Phenindone
What do the active agents in developer solution do?
Reduce exposed silver bromine crystals to metallic silver, which is deposited on the film and appears black
Why should a lid always be kept on the developer solution?
To reduce oxidation
What ways are used to reduce oxidation of the developer solution?
Preservatives in the solution
Keeping a lid on the solution
What is the pH of the developer solution?
9.6-10.0
What is used to maintain the pH of the developer solution?
An accelerator
How is chemical fogging reduced in the developer stage?
Using a restrainer
What does a restrainer in the developer do?
Improve the selectivity of the developer, ensuring that a minimal number of unexposed silver halide crystals are reduced
What builds up as the developer solution is used?
Calcium sludge
What is used to prevent the build up of calcium sludge in the developer solution?
A sequestering agent is added
What solvent for all the developer chemicals to be devolved in?
Water
