Abstract Gamma-ray absorption coefficient in some shielding materials, such as, iron, brass, lead and concrete, is measured experimentally in the present study using a Cs-137 source of energy 0.662 MeV.Two types of concrete samples are used , ordinary concrete and concrete with additive fractional weights of iron or brass or lead materials. Experimental measurements are carried out for single-layer absorbers. The dependence of gamma-ray absorption coefficient on the atomic number, and density of the absorber material is taken into account. The results showed that for concrete, the value of gamma-ray absorption coefficient can be increased if a material of high atomic number ( or density ) is added to it .
