摘要

The effect of natural background radiation is one of the most important determining factors for shelf life of high speed color negative films. Namely, high speed color negative films are inclined to suffer from increase in fog, decrease in speed and determination in graininess during their preservation. This damage is caused mostly by natural background radiation. We divided natural background radiation into three components: cosmic rays, environmental radiation, and self-contamination, and determined the fraction of the contribution of each component to this damage.
