The total mass attenuation coefficients ( μ m ) for SiO 2 {Quartz (1 1 0 1), Quartz (1 1 0 0) and Quartz (0 0 0 1)}, KAlSi 3O 8 {Orthoclase (0 1 0), Orthoclase (1 0 0)}, CaSO 4·2H 2O (gypsum), FeS 2 (pyrite) and Mg 2Si 2O 6 (pyroxene) natural minerals were measured at 22.1, 25.0, 59.5 and 88.0 keV photon energies. The γ- and X-rays were counted by a Si(Li) detector with a resolution of 160 eV at 5.9 keV. Atomic and electronic cross sections ( σ t and σ e ), the effective atomic and electron numbers or electron densities ( Z eff and N eff ) were determined using the obtained μ m values for investigated samples.
