What is the thickness of the lead in a lead apron?

The typical thickness of lead in a lead apron is 0.25 mm. This thickness provides an adequate level of protection for healthcare professionals and patients during procedures that involve x-ray exposure. Lead aprons are designed to shield the body's vital organs from the harmful effects of ionizing radiation, and 0.25 mm is generally recognized as the standard minimum thickness necessary to effectively attenuate radiation while maintaining comfort and flexibility for the wearer.

While thicker lead aprons exist, often used in specific high-radiation environments, the standard thickness of 0.25 mm is sufficient for most routine radiological procedures, balancing adequate protection with practicality in terms of weight and wearability.
