Concrete of various type have been used extensively for the adequate shielding of the radiological equipment using X and gamma rays. In its basic form, concrete is composed of pieces of inert aggregate held together by hardened cement paste. Different concrete types with special cements have been prepared. The linear attenuation coefficients of conventional concrete and concrete with supplementary mineral additives (barite and witherite) at different gamma energies (Co-60: 1.25 MeV, Cs-137: 0.662 MeV, Ir-192: 0.37 MeV) in narrow beam conditions have been measured. This paper includes some experimental data regarding the influence of barite and witherite additives on photon attenuation coefficients of concrete.
