Which shielding devices may increase the risk of cross-infection during a radiographic examination?

Contact shields are designed to be placed directly on the patient, which can present a higher risk of cross-infection. Because these shields come into direct contact with the patient's skin, they can harbor pathogens if they are not properly cleaned and disinfected after each use. This increased risk of transmitting infection between patients makes contact shields a concern in terms of infection control during radiographic procedures.

In contrast, lead shields are typically used to intercept radiation without coming into direct contact with the patient, thus minimizing the chances of cross-infection. Shadow shields are often used to block radiation from certain areas while being positioned away from the patient. Flat shields, while they can be placed on patients, generally present lower risk than contact shields when it comes to cross-infection, depending on their usage and the materials involved.
