摘要：
This study determined the interaction of radiation parameters of four biomaterials as attenuators to measure the transmitted X-rays spectra, the mass attenuation coefficient and the effective atomic number by spectrometric system comprising the CdTe detector. The biomaterial BioOss (R) presented smaller mean energy than the other biomaterials. The mu/rho and Z(eff) of the biomaterials showed their dependence on photon energy. The data obtained from analytical methods of x-ray spectra, mu/rho and Z(eff) using biomaterials as attenuators, demonstrated that these materials could be used as substitutes for dentin, enamel and bone. Further, they are determinants for the characterization of the radiation in tissues or equivalent materials. (C) 2016 Elsevier Ltd. All rights reserved.
