According to these results, it was seen that clay sand clay mixtures (especially clay and white cement) have higher linear attenuation coefficients than those of the other samples. Also,N4
sample in which micronize clay and white cement is used have higher linear attenuation coefficient than those of the other samples for all energy levels studied.It was determined that N4 has a linear attenuation coefficient of 0.7736 cm1 at Am-241, 0.3779cm1 at Cd-109, 0.0772 cm1 at Tc-99m and 0.0264 cm
