What is the best place to store unexposed x-ray film?

The best place to store unexposed x-ray film is in a lead container. This method offers optimal protection against stray radiation, which can fog or degrade the film, potentially compromising the quality of the images produced later. Lead containers are specifically designed to shield sensitive materials from radiation exposure, ensuring that the film remains unaffected until it is ready for use.

While other storage methods, such as using a darkroom, do provide a controlled environment away from light exposure, they do not necessarily protect against radiation. A puncture-resistant sealed container might protect the film from physical damage and contamination but lacks the necessary shielding against radiation. Storing the film in a warm area could pose a risk, as high temperatures may lead to chemical deterioration over time.

Thus, using a lead container stands out as the most effective way to maintain the integrity and quality of unexposed x-ray film.
