Abstract

In this work, the physically examined sodium lead calcium borate glasses doped with Pr³⁺ at different concentrations have been examined qualitatively to deduce the neutron moderation parameters for collimating the neutron beam in radiography. Physically examined glass samples have a nominal composition matrix of 20Na₂O₃-10PbO-(60-x)B₂O₃-xPr₂O₃ with 10Ca₂O, 10Ba₂O, and 10Sr₂O substitutions. The neutron moderation properties such as effective removal cross section, relative thermal lethargy, average logarithmic energy decrement, absorption cross sections, moderation power, moderation efficiency, shared energy at each collision, and average number of collisions for all the elements, and above-mentioned glass samples have been deduced. In addition, the effective or equivalent atomic number and atomic mass for neutron interaction with the glass samples has been estimated. Obtained an interesting trend with the density of the material and analysed with a code.

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.
