What is a benefit of using barrier films in radiology?

Using barrier films in radiology plays a critical role in infection control. They are specifically designed to prevent contamination of surfaces and equipment that come into contact with patients during radiographic procedures. By serving as a protective barrier, these films help to reduce the risk of transmitting pathogens from patient to equipment or vice versa.

Barrier films are particularly beneficial in settings like dental radiography, where instruments may frequently come in contact with saliva, blood, or other potentially infectious materials. They provide a safe and effective way to maintain a sterile environment, ensuring both patient and staff safety.

While speed, cost, and availability are factors that might influence equipment choices in radiology, the primary concern when using barrier films is their role in preventing cross-contamination, making option B the most relevant benefit in this context.
