dc.description.abstract In this study, the development and evaluation of new ceramic materials doped with limonite and hematite minerals in terms of their effectiveness in gamma ray and neutron shielding was investigated. The primary aim is to determine gamma-ray shielding parameters for these ceramics, using gamma photon energies emitted from the Barium-133 radioisotope at specific energy levels (81, 160, 223, 302, 356, and 383 keV). Measurements were conducted using a Canberra Ultra Ge detector to detect the intensities of radiations. The mass attenuation coefficient (mu p), half-value thickness (A0.5), mean free path (2) and effective atomic numbers (Zeff) were determined experimentally and theoretically. And, exposure (EBF) and energy absorption (EABF) buildup factor values of ceramics were determined at different mean free paths and photon energies using the EpiXS program. Intercalarily, fast neutron attenuation parameters (ER) of ceramics have also been calculated. The densities of the ceramics increased with the addition of limonite and hematite minerals, ranging from 2.61 g/cm3 to 3.12 g/cm3 as the limonite content increased from 0 wt% to 30 wt %. Similar density variations were observed with the addition of hematite. There is a direct proportional relationship between the density of the ceramics and their shielding effectiveness. The effective atomic numbers (Zeff) were ranked as C G H1 G H2 G H3 G L1 G L2 G L3, indicating that the shielding effectiveness improves with higher doping levels. The L3 ceramic (with 30 % limonite addition) sample exhibited the highest fast neutron removal cross-section values among the tested samples. The findings demonstrate that doping ceramics with limonite and hematite minerals enhances their en_US
