In this study, analysis of radiation parameters (linear attenuation coefficient, mean free path and half value layer) of pumice constituent compounds was carried out. Analyzes were done on the compounds of Al2O3, Fe2O3, SiO2, CaO, K2O and Na2O with a theoretical approach using the XCOM program for gamma photon energies 57Co (0.122 MeV; 0.1365 MeV), 133Ba (0.356 MeV), 54Mn (0.835 MeV), 137Cs (0.662 MeV), 60Co (1.173 MeV; 1.333 MeV), 65Zn (1.1155 MeV), 22Na (0.511 MeV; 1.275 MeV) and 40K (1.461 MeV). The results show that the Fe2O3 compound has the largest linear attenuation coefficient, while the largest for MFP and HVL is Na2O among other compounds.
