Abstract
The mechanical and radiation shielding performance of lead-borate-based glass samples were evaluated The density values range from for BPCB-5 to for BPCB-20. Makishima-Mackenzie’s theory was applied, and mechanical moduli were derived. The increase in BaO content made the microhardness, shear modulus, and Young’s modulus slightly decreased. Simultaneously, radiation shielding parameters were assessed within energies , and . The results of BPCB-20 sample surpasses all other samples in terms of radiation shielding capabilities. The half value layer at were and for BPCB-5, BPCB-10, BPCB-15 and BPCB-20, respectively. The samples BPCB-5 and BPCB-20 have separate radiation shielding effectiveness measurements of and for thickness of the sample. These glass samples are superior to commercial glass that is being adopted in the market such as RS-360, since the HVL for RS-360 at is.
期刊介绍:
Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
