What may happen to films left between lead screens for too long in a high-temperature, high-humidity atmosphere?

In a high-temperature, high-humidity atmosphere, films left between lead screens for an extended period are likely to become fogged due to the moisture in the environment. Fogging occurs when the emulsion layer on the radiographic film absorbs moisture, leading to a reduction in image quality. This phenomenon can create a cloudy or indistinct appearance on the film, which obstructs the clarity needed for accurate interpretation of radiographic images.

The fogging effect is exacerbated by prolonged exposure to unfavorable storage conditions, which can cause chemical changes in the film emulsion. This is critical for radiographers to understand because maintaining proper storage conditions is essential for preserving the integrity and quality of radiographic films, enabling accurate inspections and evaluations in radiographic testing.
