| The present study was carried out to estimate gamma radiation shielding properties of natural glass obsidian. For this purpose,linear attenuation coefficient, mass attenuation coefficient, mean free path, half-value layer, tenth-value layer, effective atomicnumber and effective electron number values of obsidian samples in black and brown colors were experimentally measured for661.66, 1172.23 and 1332.48 keV gamma ray energies obtained from 137Cs, and 60Co radioactive sources. Measurements wereperformed at narrow-beam transmission geometry using a NaI(Tl) scintillation detector. In addition, all these parameterswere theoretically calculated by using WinXCOM program in the energy region of 0.015 to 15 MeV. A good agreement wasobserved between theoretical and experimental values. Furthermore, energy absorption and exposure buildup factors (EABF andEBF) of obsidian specimens were determined in the energy range of 0.015 to 15 MeV using G-P fitting method. Finally, itcan be concluded that these naturally occurring volcanic glasses can be used for radiation shielding applications. |
