Abstract

• The present work is performed to find out the elemental concentration and gamma attenuation coefficients of Autoclaved Aerated Concrete (AAC) block by using EDXRF method (EDX-720) and gamma spectroscopy method using NaI(Tl) detector for Cs-137 gamma source. The various thicknesses of AAC block samples are used as attenuator for gamma ray intensity in this work. Toxic elements and radioactive nuclides are not detected by EDXRF method. It is highly attenuated to radiation shielding. So, these results will be helpful in the development of radiation shielding technology.
