First, consider the amount of material needed to provide the same amount of protection as 0.5 mm of lead, which is protection provided by many leaded aprons. At 60 keV (6.0 × 10-2 MeV), the mass attenuation coefficient, µ/ρ, of lead is 5.021 cm 2 g-1. Multiplying by the thickness of 0.05 cm and the density of lead, 11.35 g cm-3, gives 2.85.
