    The linear attenuation coefficient of clay at varying incident of energies is an important characteristic that needs to be studied and determined prior to using such a material in radiation protection. The linear attenuation coefficient and intensity as well as thickness were determined for natural clay (A) and artificially contaminated clay (B) to assess their use in radiation shielding. A narrow collimated beam of x-rays from sources with varying energies were passed through various thicknesses of clay slabs. The attenuation in the incident intensity of the beam was determined for each thickness of the clay slabs. Linear attenuation coefficients of A and B were compared with that of concrete. The results showed that linear attenuation coefficient value of artificially contaminated clay is higher than concrete by 37 % at 40keV.Therefore, artificially contaminated clay is a good absorber of radiation and can be used as x-ray wall material.
