Lesson 2 Flashcards
is a specialized area where exposed
radiographic films are processed.
Dark Room
It is designed to be completely devoid of white light to prevent film fogging, ensuring that the film retains its
diagnostic quality
Dark Room
what are the qualities of a good processing room
- Adjacent to exposure room
- No windows
- Accessible to plumbing and electrical service
- Away from damp or hot areas
- Proper film handling
- Proper illumination and ventilation
This minimizes the risk of film exposure to light or radiation during transport and ensures efficient workflow.
Adjacent to exposure room
Any exposure to white light can lead to film fogging, reducing image quality. If ventilation is necessary, lightproof vents should be used
No windows
Running water is essential for manual film processing to rinse and fix the films properly. Electrical access is needed
for automatic processors and safelights.
Accessible to plumbing and electrical service
Excessive heat and humidity can cause film fogging and degrade the quality of the chemicals used in film processing.
Ideal temperature control should be maintained.
Away from damp or hot areas
Storage racks and proper handling techniques must be in place to prevent film scratches, pressure marks, or
accidental exposure to external light sources.
Proper film handling
While the darkroom must be free of white light, safelights (using red or amber filters) should be used to provide
adequate visibility for technicians. Proper ventilation helps remove chemical fumes from developers and fixers, which can be harmful if accumulated.
Proper illumination and ventilation
is required to prevent radiation
leakage.
Shielding
Since darkrooms are often adjacent to radiographic rooms, shielding is required to prevent radiation leakage.
Lead Shielding
Recommended lead thickness for shielding is:
1.6mm (1/16 inch) lead
should be adequate to prevent
overcrowding, ensuring efficient workflow and film
handling
Darkroom size or Size of the Darkroom
What is the DARKROOM SIZE AND CAPACITY
15x9.5 ft 200 Radiograph
help in maintaining an organized and
efficient workflow, ensuring high-quality radiographs for diagnostic use.
