Abstract :In the present study, gamma-ray shielding performance was investigated using mass attenuation coefficients and exposure buildup factors for tourmaline datolite, galena, amethyst and hormirad. The mass attenuation coefficients were also calculated using GEANT4 simulation toolkit, compared with XCOM results, a good agreement between XCOM and GEANT4 results was observed. The exposure buildup factors were calculated using GP fitting method for photon energy 0.015 to 15 MeV up to 40 mfp. The hormirad is superior shielding material among than tourmaline, datolite and amethyst whereas galena is the best shielding materials in low photon energy except near to 100 keV. The investigation would be very useful for shielding application of these materials.
