A novel vanadium pentoxide doped glasses characterization for radiation shielding applications

Glasses are actively used in various fields, from industry to health. Especially, special doped glasses used in radiation areas may vary depending on the type and energy of the radiation. Glasses made of high-density and effective radiation-absorbing materials generally provide adequate protection against X and gamma rays. As an example, in this study, a 42.5P2O5-42.5B2O3-(15-x)Li2O-xV2O5 (x = 0, 2.5, 5, 10 and 15) glass system was produced using the melt quenching technique. The obtained X-ray patterns indicated that lack of crystalline peaks, verifying the glassy nature of all synthesized glass series. The glass transition temperatures and the glass thermal stability were determined using a Differential Thermal Analysis (TGA). The glass transition temperature and thermal stability was found to deteriorate with increasing V2O5 content. The radiation absorption properties of these glass system produced were investigated with 384 keV, 1173 keV and 1333 keV energized gamma using narrow beam transmission geometry. The NaI(Tl) detector system have been used to obtain γ-ray spectra. According to the obtained mass attenuation coefficients (μm) results, it has been determined that as the V2O5 ratio in the glass increases, it provides more effective results in radiation shielding. When the experimental results are compared with the theoretical XCOM results, there are a good match between the values. Finally, the radiation shielding properties of this produced glass system are compared with previously studied standard glasses to refer to the superiority of the installed systems.
