What occurs when humidity rises above 60%?

When humidity rises above 60%, films can become sticky due to the moisture in the air interacting with the emulsion layer on the film. High humidity can lead to the absorption of water into the film, which can degrade its quality by making it tacky. This stickiness can cause difficulties during handling, processing, and storage of the film, potentially ruining exposed images or causing jams in film transport systems.

Proper handling and storage conditions for radiographic films require maintaining humidity levels between specific ranges to prevent issues such as stickiness or other degradation. Balancing humidity is crucial in preserving the integrity of the films and ensuring optimal image quality for radiographic purposes.
