Lead barriers are employed primarily to protect against scattered radiation. In dental and medical imaging environments, X-ray machines generate radiation that, while focused on the area being examined, can also scatter in various directions. This scattered radiation can expose both patients and healthcare professionals to unnecessary radiation, posing a potential health risk.

Lead, being a dense material, effectively absorbs and blocks this radiation from passing through, thereby significantly reducing exposure levels. The use of lead barriers is a critical safety measure in radiology to ensure that individuals not involved in the procedure are shielded from harmful radiation. Consequently, these barriers help maintain a safe working environment while allowing necessary imaging to be performed.
