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 atomic number and effective electron number values of obsidian samples in black and brown colors were experimentally measured for 661.66, 1172.23 and 1332.48 keV gamma ray energies obtained from 137 Cs, and 60 Co radioactive sources. Measurements were performed at narrow-beam transmission geometry using a NaI(Tl) scintillation detector. In addition, all these parameters were theoretically calculated by using WinXCOM program in the energy region of 0.015 to 15 MeV. A good agreement was observed between theoretical and experimental values. Furthermore, energy absorption and exposure buildup factors (EABF and EBF) of obsidian specimens were determined in the energy range of 0.015 to 15 MeV using G-P fitting method. Finally, it can be concluded that these naturally occurring volcanic glasses can be used for radiation shielding applications.

“…The radiation intensity is affected by the distance and direction from the source generation point. The transmitted radiation intensity can be calculated using the thickness and density of the shielding film as follows 21 : Intensity of radiation that passes through the shield, Initial radiation intensity, Linear attenuation coefficient, Shield thickness (µm).…”

Radiation shielding films used in medical institutions are manufactured by mixing polymer materials with eco-friendly shielding materials. However, it is not easy to distribute the shielding material particles uniformly during the process. The uniform distribution of the shielding material particles is key to the reproducibility of the shielding performance of the films. Therefore, in this study, an air pressure mirroring particle dispersion method was developed to maintain a uniform distribution of the shielding material by dispersing the shielding material on a curved reflector through an air nozzle. The particle distribution state, density, and shielding performance of the cross-section and surface of the shielding films developed using the single-sided dispersion, double-dispersion, and air pressure mirroring particle dispersion methods were evaluated. Compared to the conventional single-sided distribution method, the shielding film produced by the air pressure mirroring particle dispersion method increased the particle packing by 41.5%, density by 12.9%, shielding material content by 22.2%, and shielding performance by 21.4%. Thus, the proposed dispersion method enables better shielding performance through uniform dispersion of shielding material, which is the most important parameter in the manufacture of low-dose shielding films.

In this study, it has been investigated of the Compton profiles (CP) of the Ar and O 2 gases using a Compton spectrometer having annular 241 Am radioactive source. The photons emitted from the radioactive source and scattered photons from the samples were recorded using HPGe detector. In order to obtain experimental Compton profiles of the samples the Warwick codes were used. The experimental results obtained were compared with the theoretical results calculated by Hartree-Fock method. The results clearly show that the experimental and theoretical results are in good agreement, especially in the high momentum region. It was observed that while the difference between the experimental and theoretical results of Ar and O 2 gases in the p z = 0 region is about 4%, this difference is below 1% after p z = 2.
