Film Processing: The Darkroom, Silver Recovery and Pollution,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

Fundamentals of Radiographic Imaging,cal diagnostic tools. At the time of discovery it was quickly realized that X-rays could be used to produce an image of the internal structures of the human body either on a photographic plate or a screen which emits light when bombarded with X-rays. This new method of imaging was an immense step fo

Is it possible by altering the voltage and the mA to increase the amount of information in the image and is it then possible to see this

Control of Film Stocks,m storage conditions and the possible effects on the image when these conditions are not met. A certain degree of latitude is possible in film storage conditions and to this end it is necessary to understand the principles and methods involved in the setting up and use of a film store.

Intensifying Screens,tensifying screen is used facing and in contact with the emulsion side of the film. Paired intensifying screens are used with duplitized screen-type film. In all cases, the emission spectrum of the screens is matched to the spectral sensitivity of the film emulsion. Intensifying screens intensify th

Automatic Exposure Control,ssociated with the choice of exposure factors but unfortunately introduces new problems not apparent with manual exposure selection. Several devices are available but basically only two methods are used, phototiming and ionization timing. Phototiming is used for automatic exposure control for both l
