Evaluation of physical and radiation shielding properties of Bi2O3–B2O3 glass doped transition metals ions

摘要: Abstract Bismuth borate glasses of formula 60% Bi2O3 and 40% B2O3 doped 0.7 wt % one the transition metal oxides; TiO2, Cr2O3, V2O5 or Fe2O3 were prepared using melting-annealing method. The optical transmittance spectra have been studied reveal UV transmission bands related to different valence states ions. Electrical conductivity many physical parameters also investigated such as; bandgap (Eopt), refractive index (n), reflection loss (RL), molar refractivity (Rm), polarizability (αm), dielectric constants (e), coefficient (T) metallization criterion (M Criterion). effectiveness as radiation protective shield was evaluated calculated by Monte Carlo N-Particle Transport Code (MCNP) Medical Internal Radiation Dose (MIRD) male human model. Many shielding deliberated linear attenuation coefficient, effective removal cross section (ΣR), efficiency (RPE %), tissue weighting factors (Wt), in addition a comparison between experimental simulated gamma coefficients at numerous energies. high stable properties against irradiation. concentration heavy Bi3+ ions presence with their variable configurations, provide behavior decreased life time risk for cancer about five times.
