Paper Abstract

Fogging of radiographic films can be characterized by a photographically equivalent radiographic exposure dose (Ex-eq). It is shown that within the limits of the experiments Ex-eq is independent of the moment of fogging i.e. before or after the radiographic imaging, and of the radiation intensity levels in the radiographic beam in case of no-screenexposure, but is dependent in case of an exposure with fluorescent screens and fogging by light. A dependent Ex-eq causes apparent sensitometric anomalies. The study warns against darkroom light fogging mainly when unloading cassettes.
