The first step in manual film processing is:
development
rinsing
fixing
washing
drying
In manual film processing, the rinsing step is necessary because it:
removes the silver halide crystals from the emulsion
slows down the fixing process
removed the developer from the film and stops the development process
reduces the energized silver halide crystals to black metallic silver
The film emulsion is hardened during:
development
rinsing
fixing
washing
drying
The hydroquinone in the developer brings out the _______ tones, whereas the elon in the developer brings out the _____ tones on a dental radiograph.
balck; white
white; black
gray: gray
black; gray
The size of the darkroom is determined by the following factors except:
volume of radiographs processed
type of processing equipment used
humidity level of the room
number of persons using the room
Any light leaks of white light into the darkroom will cause
film fogging
film reticulation
overdevelopment of films
underdevelopment of films
Unopened boxes of radiographic film should not be stored in the darkrooms because
chemical fumes from the processing solutions may fog the film
continued exposure to the safelight is not recommended
the box may have a tear that may exposure the film
processing solutions could splash onto the box
The thermometer for manual processing should be placed in the
developer solution
water bath
fixer solution
all of the answers are correct
A replenisher is added to the processing solutions to:
compensate for the loss of solution strength
ensure uniform results between solution changes
compensate for the loss of volume of solution
compensate for oxidation
all of the answers are correct
How often should the processor be cleaned?
once per week
once per month
once per day
whenever the solutions are changed
