Inspection of Radiation Shielding Proficiency and Effect of Gamma-Ray on ESR, Thermal, and FTIR Properties of Modified Borate Bioglasses by CuO

Abstract

This research studied the various properties of copper oxide (CuO)-doped bioactive borate glasses extensively for their applications in different fields. The radiation shielding properties, such as gamma-ray, neutron, electron, and proton radiation shielding, were investigated. Further, the glasses’ mass attenuation coefficients were measured with a NaI(Tl) detector; their derivative gamma shielding parameters were studied theoretically with the Phy-X/PSD program. Every increase in the CuO % increased the fast neutron (Σ R ) gamma attenuation and effective removal cross-sections. Additionally, mass stopping power (MSP) and projected range (PR) for protons and electrons delivered good results in the 10 KeV‒10 MeV kinetic energy range, as computed by the SRIM code. Also, the free-radical densities were measured via electron spin resonance to estimate the absorbed doses during accidental irradiation. The extensive reduction of the dose detection threshold (2 Gy) required the estimation of the signal of the non-irradiated sample. This work also studied the effects of applied microwave power incidence and absorbed dose on Cu-containing borate bioglasses. Finally, the thermal annealing of the emerging peaks, which were due to the irradiation signal-to-noise ratio and energy dependence, was studied to estimate the stabilities of such peaks. This modified material is recommended to detect and monitor the gamma-radiation dose because of its good dosimetric properties. Finally, regarding the presence of the two borate groups, triangular (BO 3 ) and the tetrahedrally coordinated (BO 4 ), in their definite and typical wavenumbers, the FTIR spectra displayed simplified vibrations that were close to those of many bioglasses. This paper provides complementary results for the authors previous research examined this glass for low photon dose measurements using luminescence characteristics .
