Comparative investigations of gamma and neutron radiation shielding parameters for different borate and tellurite glass systems using WinXCom program and MCNPX code

In the current study, promising glass composites based on vanadium pentoxide (V2O5)-doped zinc borate (ZnB) were investigated in terms of their nuclear-radiation-shielding dynamics. The mass and linear attenuation coefficient, half-value layer, mean free path, tenth-value layer, effective atomic number, exposure-buildup factor, and energy-absorption-buildup factor were deeply simulated by using MCNPX code, Phy-X PSD code, and WinXcom to study the validation of ZBV1, ZBV2, ZBV3, and ZBV4 based on (100−x)(0.6ZnO-0.4B2O3)(x)(V2O5) (x = 1, 2, 3, 4 mol%) samples against ionizing radiation. The results showed that attenuation competencies of the studied glasses slightly changed while increasing the V2O5 content from 1 mol% to 4 mol%. The domination of ZnO concentration in the composition compared to B2O3 makes ZnO substitution with V2O5 more dominant, leading to a decrease in density. Since density has a significant role in the attenuation of gamma rays, a negative effect was observed. It can be concluded that the aforementioned substitution can negatively affect the shielding competencies of studied glasses.

Prepared Glass

In this study, borosilicate host (H) and seven (S1-S7) samples are prepared by traditional melt-quenching technique. The samples are singly (S1, S2) and doubly (S3-S7) doped with deferent contents of Tb3+ and Dy3+ ions. All samples are analyzed and characterized by XRD (x-ray diffraction), ATR-FTIR (Attenuated total Reflectance-Fourier transform infrared) spectroscopy, TGA/DSC (Thermogravimetric analysis/Differential scanning calorimetry), and Raman spectroscopy. Moreover, the radiation shielding parameters of mentioned glasses such as mass attenuation (?/?), mean free path (MFP), and half-value layer (HVL) are evaluated within the energy of 0.015MeV-15MeV. These parameters are theoretically investigated and evaluated by using XCOM, WINXCOM, and Phy-X programs in addition to the other relevant equations. The ATR-FTIR measurement and Raman spectroscopy results confirmed the unit structure of BO3 and BO4 groups as the main compound as well as the Aluminum-oxide (Al-O-Al) and zinc-oxide (ZnO4) bonds. The transition (Tg), onset crystallization (Tx), crystallization (Tc) temperatures, and weight loss were identified from DSC and TGA findings, respectively. Also, the prepared glass shows good stability against crystallization, as reflected by (?T) variation. Furthermore, the radiation shielding parameter findings show good enhancement of the performance of the samples. However, upon these findings, one can say that these glasses could be used and utilized for radiation shielding purposes.
