What dimensions describe an impregnated lead apron?

An impregnated lead apron is designed to provide protection from ionizing radiation, especially in a clinical or procedural environment. The dimensions and thickness of the apron are essential factors that determine its effectiveness and usability.

The correct choice indicates a dimension of 1' X 2' and a thickness of .25 mm. This size is practical for ensuring adequate coverage of vital organs while allowing freedom of movement for the wearer, which is crucial in medical settings. The thickness of .25 mm of lead is a commonly used standard, as it balances protection with comfort. Lead aprons typically aim to reduce exposure to radiation to safe levels while still being lightweight enough that practitioners can wear them without undue fatigue during procedures.

Understanding these specifications is vital because they ensure that the apron provides sufficient attenuation of radiation, which is critical in radiology practices to protect both patients and healthcare workers.
