In this paper, the EPICS2017 photoatomic database was used to evaluate the photon mass attenuationcoefficients and buildup factors of soils collected at different depths in the Philippine islands. Theextraction and interpolation of the library was accomplished at the recommended linear-linear scales toobtain the incoherent and total cross section and mass attenuation coefficient. The buildup factors wereevaluated using the G-P fitting method in ANSI/ANS-6.4.3. An agreement was achieved between XCOM,MCNP5, and EPICS2017 for the calculated mass attenuation coefficient values. The buildup factors werereported at several penetration depths within the standard energy grid. The highest values of bothbuildup factor classifications were found in the energy range between 100 and 400 keV where incoherent scattering interaction probabilities are predominant, and least at the region of predominantphotoionization events. The buildup factors were examined as a function of different soil silica contents. The soil samples with larger silica concentrations were found to have higher buildup factor values andhence lower shielding characteristics, while conversely, those with the least silica contents haveincreased shielding characteristics brought by the increased proportions of the abundant heavier oxides.
