RT110 Quiz Flashcards
Recommended lead thickness for shielding:
1.6 mm (1/16 inch) lead
a specialized area where exposed radiographic films are processed. It is designed to be completely devoid of white light to prevent film fogging, ensuring that the film retains its diagnostic quality
Darkroom
DARKROOM SIZE AND CAPACITY
15x9.5 FT 200 Radiograph
These divisions help in maintaining an organized and efficient workflow, ensuring high-quality radiographs for diagnostic use.
Darkroom divisions
Ensures that chemicals, safelights, and film processing conditions are maintained at optimal levels. Regularly checks for any film artifacts, chemical contamination, or processor malfunctions.
QUALITY CONTROL SECTION
A designated area for storing processed films and patient records. Proper film archiving methods must be used to ensure easy retrieval and prevent film deterioration
FILE ROOM
Contains a film viewing area where processed radiographs are inspected for quality before storage or diagnosis.
VIEWER SIDE
A type of dark room entrance which is Simple and effective for small departments
Single door
Type of dark room entrance that Ensures continuous processing without interruptions
LIGHT LOCK OR DOUBLE DOOR SYSTEM
A darkroom entrance that Provides better air circulation and eliminates odor
LABYRINTH OR MAZE ENTRANCE
A darkroom entrance tha is considered the most effective design for uninterrupted workflow
REVOLVING DOOR
An illuminator that is used For maintenance activities
White light
Provides low-intensity illumination that allows technicians to handle films safely without causing fogging.
-For safe film handling
SAFE LIGHT
-Used during the hardening and washing stages of processing to inspect film progress.
-Must be turned on only when necessary.
-Ensure that no open box of film is on the dry side and that no film is under the developer solution or stop bath before switching it on.
-For checking films in fixer
Wet Film Illuminator
Used for blue-sensitive films (calcium-tungstate screens). It transmits wavelengths longer than 550 nm.
Amber filter
Used for green-sensitive films (rare-earth screens). It transmits light above 600 nm, preventing fogging
Red filter
Prevents light reflection
Wall Finish
HUMIDITY CONTROL
40-60%
Leads to reduced contrast and increased fog in radiographs.
Above 60%
Increases the risk of static artifacts, which appear as unwanted marks on the film
Below 40%
High temperatures reduce image contrast and increase film fog.
19.44-20°C
or
(67 degree F - 68 degree F)
A film could be stored for a long period if the temperature maintained
10°C
Or
(50 degree F)
Air movement in the darkroom should be maintained at
15 to 25 feet per minute
-The primary workspace for handling films.
-A small table, typically 28 inches long and 17 inches wide, though size may vary based on darkroom dimensions.
-Used for loading and unloading films into cassettes and hangers.
Height: Must be 3 feet for comfortable use
