During X-ray diagnostics, lead aprons made of a thin layer of lead are used in order toprotect against the harmful effects of X-ray radiation. Determine, by what factor is the intensity of Xray radiation reduced after passing the apron of thickness 0.5 mm. The mass attenuation coefficientfor a radiation source with an energy of 140 keV is μm = 2 cm2/g. Density of lead ρ = 11.35 g/cm3
