In this study, the gamma radiation attenuation features of barium
zirconat, barium titanate (IV), magnesium nitride, barium pyrophosphate
and silicon carbide were studied using the narrow beam geometrical setup
in the energy range of 81 keV-1333 keV. The mass attenuation
coefficients have been measured and then used to obtain half value
layers, mean free paths and effective atomic numbers of the present
materials. It is found that the change in the mass attenuation
coefficient is considerable for low photon energies (between 81 and 276
keV), whereas the change in this parameter is comparatively small
between 303 and 835 keV photon energies. At high energies (1173, 1275
and 1333 keV), the results showed that the mass attenuation coefficient
values for all samples are almost the same which revealed that the
present ceramics does not have a significant effect on the amount of
attenuation of photon at higher energies. The radiation protection
efficiency results revealed that BaZrO3 has the maximum capability in
attenuation of gamma photons followed by BaTiO3 and Ba2P2O7, especially
at low energies.
