What Student Need to Know about Dark Room Procedures In Radio Diagnosis

In radiographic practice provision must be made to handle unprocessed film material outside the protective environment of its cassette. All film material used in radiography is sensitive to white light with resultant film fogging and to avoid this when handling unprocessed film it is usual to provide 1. A film handling room from which white light can be excluded when required. Historically, such a room is called the radiographic darkroom 2. Light sources within the darkroom providing a visible light spectrum outside the range of spectral sensitivity of the film being handled. Proper film processing is vital to the production of a quality radiograph. Many believe that the use of appropriate exposure factors is the only component necessary to produce a “good” film. This is far from the truth. The production of a good-quality radiograph depends on many factors, one of which is film processing. When manual processing was the norm in human hospitals, it was said that 90% of all poor-quality radio
