dc.description.abstractThis research compares the radiation shielding properties of clay bricks containing rice husk ash, fly ash and shells by gamma spectrometer. Which uses the Ba-133 Cs-137 Na-22 and Co-60 radiation source at the energy values from 0.365 - 1.332 MeV. The results showed that the brick has the content of rice husk ash The coefficient of attenuation is equal to 0.098174 cm2/g at energy 0.365 MeV and decreases to 0.054671 cm2/g when the energy increases to 1.332 MeV. Mon brick with fly ash. The coefficient of attenuation is equal to 0.098278 cm2/g at energy 0.365 MeV and decreases to 0.053406 cm2/g when the energy is increased to 1.332 MeV. It has a coefficient of mass attenuation equal to 0.097982 cm2/g at energy 0.365 MeV and decreases to 0.054221 cm2/g. When the energy increases to 1.332 MeV. Therefore, it can be concluded that Clay bricks that contain fly ash have better radiation barrier properties than clay bricks containing rice husk ash and shells.en_US
