摘要：

Monte Carlo (MC) model based on FLUKA code was used to calculate the mass attenuation coefficients of the widely used non-irradiated normoxic polymer gel dosimeters, namely nMAG and nPAG gels, in polychromatic X-ray field. First, monochromatic beam attenuation was modelled, and the results were validated with NIST reference data and discrepancy was found <1%. In the second part the simulation was repeated with polychromatic X-ray spectra used in the diagnostic and therapeutic medical physics and mass attenuation coefficient values were derived for normoxic polymer gels and water medium for the reference purposes. The data obtained by this work can be used for the analysis of gel dosimeter's behavior in polychromatic photon radiation fields.
