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
Loading bench
-Located under the loading bench for convenient access.
-Made of metal with separate compartments to store different film sizes.
-Stores open boxes of film, allowing for quick and easy loading into cassettes
FILM BIN
-Positioned above the loading bench for easy retrieval.
-Hangers are arranged on two parallel bars, with handles placed on top.
-Different hanger sizes should be organized properly for efficiency.
Storage of hanger
-Mounted above the loading bench for storing unopened film boxes.
-Also includes space for cassette storage.
-Acts as alternative storage when a film bin is unavailable
Storage compartments
-A compartmentalized box for exposed and unexposed films.
-Installed through the wall between the darkroom and exposure room.
CASSETTE TRANSFER CABINET (PASS BOX)
-Should be placed near the loading bench for convenience.
-If using a film bin, it should be positioned close by.
If not, it should be placed under the bench to save space
WASTE RECEPTACLE
Positioned on the side of the darkroom, near the loading bench.
Divided into two sections:
Upper portion: Stores various film boxes.
Lower portion: Stores chemical solutions for film processing.
STORAGE CABINET
A machine that automates film processing through different stages, including developing, fixing, washing, and drying.
AUTOMATION (AUTOMATIC PROCESSOR)
Used for manual film processing, positioned opposite the loading bench to prevent solution splashes in the Dry Section
PROCESSING TANK
PARTS OF PROCESSING TANK
MASTER TANK
INSERT TANK
Acts as a jacket to hold the insert tanks. Provides a water compartment between insert tanks for rinsing and washing films
Master tank
A removable container that holds individual chemical solutions (developer, fixer). Made of stainless steel or hard rubber plastic for durability and resistance to chemicals
Insert tank
Used for rinsing films after fixing, ensuring all residual chemicals are removed.
Allows more films to be processed efficiently within a short period
Wash tank
TYPES OF WASH TANK
SINGLE COMPARTMENT WASH TANK
CASCADE WASH TANK
Fresh water continuously circulates over the film surface. Connected to a water pipe with a drainage hole on the opposite side of the water inlet for excess water removal
SINGLE COMPARTMENT WASH TANK
Divided into two compartments:
First stage: Initial washing.
Second stage: Final washing for complete chemical removal. More effective than a single compartment wash tank. Water flows from bottom to top, preventing contamination.
CASCADE WASH TANK
Stainless steel clips used to hold films during processing.
PROCESSING HANGER
Has crossbars and a rigid frame with four clips. Used for large radiographic films
SHEET FILM HANGER
Specially designed for dental radiographs. Made of stainless steel with attached film clips
DENTAL FILM HANGER
Used for 10mm roll films (fluorography
WHOLE FILM HANGER
Measures the temperature of processing solutions to maintain optimal chemical activity. Helps prevent image distortion due to incorrect temperature.
THERMOMETER
Used for preparing and mixing chemical solutions for film processing.
Requires two separate sets: One for developer, One for fixer.
MIXING EQUIPMENT
Ensures easy pouring of solutions.
Plastic funnel
Used for stirring solutions
Stainless steel or paddle
