Which type of shielding is preferred during a surgery for which a sterile procedure is required?

Shadow shielding is preferred during a sterile surgical procedure because it allows for the effective protection of both the patient and the surgical team from radiation exposure while maintaining the sterility of the environment. This type of shielding typically involves the use of a lead shield that is positioned overhead or to the side, casting a "shadow" of protection in the direct path of the radiation source.

Since traditional shielding methods, such as flat lead sheets, lead aprons, and lead gloves, can compromise the sterile field—especially if they come into direct contact with surgical instruments or the patient—shadow shielding is advantageous. It can be adjusted to ensure maximal protection without interfering with the surgical procedure or the sterile environment, thus balancing the need for safety against radiation exposure with the need to maintain strict infection control protocols.
