The shielding features of amethyst, chalcedony, crystal rock, milky, pink, flint, and jasper quartz were calculated. The seven varieties of quartz were collected within the territory of the state of Zacatecas in Mexico. Shielding characteristics include the linear attenuation coefficients, the effective atomic numbers and the mass interaction coefficients for 1 keV to 100 GeV photons. The interaction coefficients were calculated for the coherent scattering, the photoelectric absorption, the Compton scattering, and the pair production occurring in the electric field of the atomic nucleus and the electrons. The linear attenuation coefficients were compared with those of the Portland concrete widely used as radiation shielding. In the low energy region where the photoelectric absorption is dominant the mass interaction coefficients and the total linear attenuation coefficients have three resonances due to the Si, Ca and Fe concentration, these resonances are also noticed in the effective atomic number. For photons below 60 keV the shielding performance of quartz can be used to shield X-ray devices working with less than 60 kV.
计算了紫水晶、玉髓、水晶岩、乳石英、粉石英、燧石和碧玉石英的屏蔽特性。这七种石英品种是在墨西哥萨卡特卡斯州境内采集的。屏蔽特性包括1keV至100GeV光子的线性衰减系数、有效原子序数和质量相互作用系数。计算了在原子核和电子电场中发生的相干散射、光电吸收、康普顿散射和电子对产生的相互作用系数。将线性衰减系数与广泛用作辐射屏蔽的波特兰水泥的线性衰减系数进行了比较。在光电吸收占主导的低能区域，由于硅、钙和铁的浓度，质量相互作用系数和总线性衰减系数有三个共振，这些共振在有效原子序数中也能观察到。对于能量低于60keV的光子，石英的屏蔽性能可用于屏蔽工作电压低于60kV的X射线设备。
