A gamma-ray fog tends to reduce the effeciive contrast and speed of a photographic material and to increase the graininess. The consequences of the first two effects can be minimized by proper choice of printing-paper grade and by increasing camera exposure, with the result that the increase of graininess may be the limiting factor. A film for use in the presence of gamma rays should have as low a speed as lens and exposure-time requirements will permit. Additional desirable features are: a high ratio of light to gamma-ray sensitivity, a high contrast, and a long density range over which the useful gradient is maintained. (auth)
