Why should strong X-ray film be stored in lead containers?

Storing strong X-ray film in lead containers is crucial for minimizing exposure to stray X-rays, which can fog or degrade the quality of the film. Lead acts as a shielding material that absorbs X-ray radiation, preventing it from interacting with the film. This is essential because even a small amount of stray radiation can compromise the integrity of the images produced, leading to misdiagnosis or the need for retakes.

The use of lead containers not only helps to preserve the film's clarity and detail but also extends the lifespan of the film by providing a barrier against unnecessary exposure. This protective measure is critical in ensuring that the diagnostic quality of the X-ray remains intact until it is ready to be used.
