The problem of latent-image fading in dosimetric film is usually avoided by exposing a set of calibration films to a known source of gamma or x-radiation simultaneously with the exposure of experimental films to an unknown source. Both the experimental and calibration films are then developed together avoiding any difference in fading. This procedure breaks down if the unknown radiation intensity is very high while the calibration source intensity is very low, requiring comparatively long calibration exposures. Experiments were conducted in an effort to eliminate the above latent-image fading problem.
