Abstract
This work presents the calculation of the mass attenuation coefficient (μ) of lunar, Martian and terrestrial samples in function of the energy. WinXCOM software was employed to determine the μ values for the samples in the range from 1 keV to 100 GeV. The obtained values were practically the same for energies larger than 100 keV, but marked differences among the samples were observed for energies below 25 keV, which is the energy range of interest for the XRF system used in space probes.
