The study investigates the radiation shielding properties of new
types of ceramics undoped and doped with Terbium oxide (Tb4O7).
These materials were analyzed through theoretical calculations
using the WinXCom code. Ceramic content was planned as
40Al2Si2O5(OH)4-30KAlSi3O8-(30-x) SiO2-xTb4O7 where varies from
0 to 30 weight%. The mass attenuation coefficient (μρ), half-value
thickness (0.5), effective atomic numbers (Zeff ), and electron
densities (Nel) were determined theoretically. Also, exposure (EBF)
and energy absorption (EABF) buildup factor values of ceramics were
determined theoretically using the EpiXS program. The theoretical
densities of the ceramics increased with the addition of Tb4O7,
ranging from 2.646 g/cm³ to 4.041 g/cm³ as the Tb4O7 content
increased from 0 wt% to 30 wt%. Increasing the density of a ceramic
material through doping also plays a key role in improving its ability
to absorb and attenuate radiation. The findings demonstrate that
doping ceramics with Tb4O7 enhances their shielding capabilities
against gamma radiation. After this study has established the
necessary infrastructure, the aim is to perform experimental measurements
and compare the results with those of this study. We also
believe that this study will provide the basis for future experimental
studies. We believe this study’s results of this study may be useful in
technological applications.
