| Abstract | ||||
| Cosmic radiation one of the most important challenges scientists have to deal with due to further developing in the space travel. High-energy particles have a bad effect not only on human beings but also on electronics even in microsatellites or unique unmanned spacecraft. The purpose of this work was to investigate particles found in cosmic radiation and how to decrease its impact on organic and inanimate matter. We provide a new developed (Bi2O3-B2O3) glass system incorporated with silica from rice straw ash (RSA) with composition equation{(70-x) [80SiO2 – 20B2O3]- 30Na2O – x Bi2O3}, where x:(0, 5, 10, 15, 20), and explain why this glass can assist protective spaceships or satellites from cosmic radiation by studying glass samples ability to block gamma rays, protons and alpha particles. The purity and chemical composition of the silica are determined using XRF. In addition, WINXCOM software is used theoretically to calculate the shielding parameters like linear attenuation coefficient, half value layer, mean free path and the effective atomic number across a broad range of gamma-ray energies (0.1- 15 MeV). The ion distribution and ionization within glass samples were tracked using TRIM software. | ||||
