For gamma and X-rays shielding, it is necessary to have the protection characteristics such as linear attenuation coefficient and buildup factor. These factors have been less studied for sources such as X-rays with a continuous energy spectrum. In this study, the linear attenuation coefficients and flux buildup factors were investigated for X-ray photons (commonly applied in industrial radiography) having a continuous energy spectrum in the endpoint energy range of 75 to 340 keV for different materials, including water, concrete, aluminum, iron, tin, lead and uranium to thicknesses of 10 mean free paths (mfp) using the Monte Carlo calculation. Flux buildup factor values were parameterized as a function of mfp, and the related parameters were quantified for each source-shield configuration. Using the fitting parameters, it is possible to obtain the flux buildup factors for each of the X-ray sources and any desired thickness of the shield.
