Abstract The demonstrations impact of CeO 2 on the radiation shielding properties SiO –B O 3 –BaO–Li glasses has been investigated. observed trend in density ρ ranged from 3.127 to 4.022 g/cm³, whereas molar volume V m these decreased. half-value layers (HVL), and mean free paths (MFP) CL reinforce notion that presence Ce ions, particularly , enhances ability glasses’ attenuate gamma rays. effective electron ( N eff ) increases with addition suggesting a correlation between enhancement...
In view of their superior soft tissue contrast compared to computed tomography, magnetic resonance images are commonly involved in stereotactic radiosurgery/radiotherapy applications for target delineation purposes. It is known, however, that geometrically distorted, thus deteriorating dose delivery accuracy. The present work focuses on the assessment geometric distortion inherent used treatment planning and attempts quantitively evaluate consequent impact delivery. distortions 3 clinical...
Abstract Based on the experimental and theoretical radiation attenuation, this study produced tested a composite material made of polyester reinforced with SnO at varied concentrations abbreviated as Pol-SnO x , where = 0–60% steps 20 wt% Also, samples were doped different particle sizes: Micro, Nano, 50% Micro/50% Nano mix to investigate effect size attenuation performance. In photon energy range 0.015–15 MeV, their shielding properties empirically determined using an HPGe detector...
We describe the design of a fixed positron emission tomography (PET)/CT facility and use simulated instantaneous dose-rate plot to visually highlight areas potentially high radiation exposure. also illustrate practical implementation basic protection principles based on distance shielding minimisation time spent in hot areas. Staff whole body doses for 4 years are presented with results an optimisation study analysing dose arising from different phases within each using direct reading...
In an attempt to reutilize marble waste, a new approach is presented in the current study promote its use field of shielding against ionizing radiation. this study, we aimed develop novel and sustainable/eco-friendly lead-free radiation material by improving artificial (AM) produced from waste combined with polyester reinforcing it bismuth oxide (Bi2O3) nanoparticles. Six samples AM doped different concentrations (0%, 5%, 10%, 15%, 20%, 25%) Bi2O3 nanoparticles were prepared. The linear...

Different rock types (syenogranite, alkali feldspar granite and quartz syenite intruded by microgranite dikes veins) were investigated in the Nikeiba region Egypt. The main components of studied intrusive rocks, comprised granites syenite, are plagioclase, amphibole, biotite, K-feldspar different proportions. Ground gamma ray measurements show that syenogranite, have highest radioactivity (K, eU, eTh their ratios) comparison with granite. Geochemically, enriched large-ion lithophile elements...
