摘要: Abstract The shielding features of amethyst, chalcedony, crystal rock, milky, pink, flint, and jasper quartz were calculated. seven varieties collected within the territory state Zacatecas in Mexico. Shielding characteristics include linear attenuation coefficients, effective atomic numbers mass interaction coefficients for 1 keV to 100 GeV photons. calculated coherent scattering, photoelectric absorption, Compton pair production occurring electric field nucleus electrons. compared with those Portland concrete widely used as radiation shielding. In low energy region where absorption is dominant total have three resonances due Si, Ca Fe concentration, these are also noticed number. For photons below 60 keV performance can be shield X-ray devices working less than 60 kV.
