|
Acetic Acid |
A chemical in the fixer solution that provides the acid medium to stop further development by neutralizing the alkali of the developer.
|
|
|
Acidifier |
A chemical (acetic acid) in the fixer solution that neutralizes the alkali in the developer solution and stops further action of the developer. |
|
|
Activator |
A chemical (usually sodium carbonate) in the developer solution that causes the emulsion on the radiographic film to swell. Initiates the reducing action of the developing agents. Sodium carbonate makes the developer alkaline. |
|
|
Automatic Processor |
A machine that develops, fixes, washes, and dries radiographic film.
|
|
|
Darkroom |
A light-tight room with special safelighting where x-ray film is handled and processed. |
|
|
Daylight loader |
A light-shielded compartment attached to an automatic processor so films can be unwrapped in a room with a white light. |
|
|
Developer |
The chemical solution used in film processing that makes the latent image visible.
|
|
|
Elon |
Developer reducing agent that converts exposed silver halide crystals to black metallic silver. Builds up gray tones in the image. |
|
|
Film Feed Slot |
Opening in an automatic film processor where the film is inserted for processing. |
|
|
Film Hanger |
A stainless steel hanger equipped with clips used to hold films during manual processing. |
|
|
Film Recovery Slot |
Opening in automatic film processing unit where the finished radiograph exist at the completion of the processing cycle.
|
|
|
Fixer |
A solution of chemicals that stops the action of the developer and makes the image permanently visible. |
|
|
Fixing Agent |
Sodium thiosulfate, also known as “hypo” or hyposulfite of sodium. It is one of several chemical ingredients in the fixer solution and functions to remove all unexposed and any remaining undeveloped silver bromide grains from the emulsion. |
|
|
Hardening Agent |
Potassium alum, one of the chemicals of the fixing solution. Functions to shrink and harden wet emulsion. |
|
|
Hydroquinone |
Reduces (converts) exposed silver halide crystals to black metallic silver. Slowly builds up black tones and contrast.
|
|
|
Latent Image |
The invisible image produced when the film is exposed to x-ray photons. Image remains invisible until the film is processed. |
|
|
LED (light-emitting diode) |
A semiconductor device that emits lighting when electrical current passes through it. Used for safelighting the darkroom. |
