In diagnostic imaging, what is the most widely used lead equivalent thickness for lead aprons?

The most widely used lead equivalent thickness for lead aprons in diagnostic imaging is 0.5 mm. This thickness provides a balance between adequate radiation protection and comfort for the wearer.

Lead aprons are designed to reduce exposure to ionizing radiation during procedures such as X-rays and fluoroscopy, and the 0.5 mm thickness has been established as effective for attenuating scattered radiation, which is most commonly encountered in diagnostic imaging settings.

Thicker lead aprons, such as those with a lead equivalence of 1.0 mm or 1.6 mm, may be used in specific situations where higher levels of radiation are anticipated, particularly in interventional procedures or radiation therapy. However, they can be heavier and potentially uncomfortable for the wearer. Conversely, a lead equivalent thickness of 0.4 mm may not provide sufficient protection for certain imaging scenarios, making 0.5 mm the standard for routine diagnostic procedures.
