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 light-weight 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.
