Abstract

In this paper, we use a narrow collimated beam of mono- energetic gamma rays emitted from the radioactive source 137Cs (662 keV) and the system of measuring gamma rays UCS-20 associated with the sodium iodide detector NaI (Tl) to determine the homogeneity of the building materials, Granite, Marble, Cement, Ceramic and Bricks. The homogeneity test was determined from the percentage difference between the transmitted intensity of gamma-rays and the linear attenuation coefficient at different positions for each sample of the material then the percentage of standard deviation was checked.
