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 stainless steels (SSs) are considered as technologically and industrially important materials because of their almost endless number usage. The SSs can be categorized traditionally into six groups: ferritic, austenitic, ferritic-austenitic, martensitic, martensitic-austenitic and precipitation hardening (PH) stainless steels (Alım et al, 2020a). Because temperature has a deterministic effect on properties and structure of stainless steels, this classification based on their structure was made at room temperature.…”

In this study, it has been focused on the investigation of particle-shielding performances of precipitation-hardening stainless steels (PH-SSs). In line with this focus, the stopping powers and ranges values of four different PH-SSs (15−5PH, 15−7PH, 17−4PH and 17−7PH) for energetic charged particles (proton, electron and alpha particles) were carried out in the kinetic energy range of 0.01-20 MeV. In addition, the fast neutron removal cross-section values of PH-SSs examined for neutrons were calculated at 4.5 MeV. In order to achieve a remarkable conclusion about the particle-absorbing capacities of the PH-SSs investigated, all calculations were also performed for some concretes (steelmagnetite, steel-scrap and ordinary concretes) used as shielding materials in nuclear applications. The results obtained were comparatively presented as a function of kinetic energy of particles. In addition, the results obtained were evaluated in terms of both types of particle and phase structures of materials examined. According to the results obtained, it was observed that the all investigated parameters are independent of phase structures of PH-SSs, that the all calculated parameters for PH-SSs examined are very close to each other, and that the particle-shielding performances of PH-SSs under examination are better than comparison concretes. As a result of the data obtained from this study, it was observed that PH-SSs can be used as an alternative material in areas where particle radiation safety is required because of their superior characteristic and shielding properties.
