传统上，用于诊断放射学的防护围裙的吸收特性是以铅当量厚度为单位规定的。当铅是围裙中唯一的高原子序数成分时，这是适当和准确的。然而，在制造轻质防护服的尝试中，一些制造商已经包括在感兴趣的能量范围内具有k个吸收边缘的其他元件，以提供具有更轻重量的等效吸收特性。随着这些其他高原子序数元素的加入，服装的铅当量成为光子能量的函数。这一点必须得到供应商的认可和规定，因为铅防护服用于诊断放射学以外的环境，当规格基于诊断X射线能量范围时，其屏蔽效益可能远低于预期。
Traditionally, the absorption properties of protective aprons used in diagnostic radiology have been specified in units of lead equivalent thickness. This is appropriate and accurate when lead is the only high-atomic-numbered component in the apron. In an attempt to manufacture lightweight protective apparel, however, some manufacturers have included other elements with k absorption edges in the energy range of interest, to provide equivalent absorption properties with less weight. With these other high-atomic-numbered elements added, the lead equivalence of the apparel becomes a function of the photon energy. This must be recognized and specified by the supplier, because lead apparel is used in environments other than diagnostic radiology, where the shielding benefits may be substantially less than expected when specifications are based on the diagnostic x-ray energy range.
