The linear attenuation coefficient and mass attenuation coefficient of the soil samples decrease but half value layer, tenth value layer, mean free path and transmission factor enhance with increment of photon energy. S1 has the maximum radiation protection efficiencies (RPEs) between 0.08 and 15 MeV in the present soil samples while S2 has the minimum RPEs between 0.015 and 0.1 MeV later S6 has the minimum RPEs between 0.15 and 15 MeV. Both effective atomic number (Zeff) and effective electron density (Neff) values decrease gradually up to 1.5 MeV afterwards the Zeff and Neff values gradually enhance up to 15 MeV. Except for 0.05 and 0.06 MeV, the effective conductivity (Ceff) values of S6 are the smallest and S2 has the maximum Ceff values in soil samples. The exposure buildup factors (EBFs) and energy absorption buildup factors (EABFs) descend from 20 to 1 mfp. The fast neutron removal cross sections (FNRCs) of the soil samples decrease as soil depth increases. Consequently, radiation absorption properties and FNRCs vary with chemical content and densities of the soil samples.
