“…The linear and mass attenuation coefficients (μ) for all the three HPC series were measured at photon energy of 0.663 MeV and compared with the results which available in the literature [8], [9], [15]- [17], [22], [31]. The measured results are listed in Table III. It can be seen that the highest mass attenuation coefficient values at 0.663 MeV γ-ray energy obtained from heavy HPCs (BR and HM) and they are close to X-ray mass attenuation coefficient values of NIST [22].…”

“…Reference [9] measured the attenuation coefficients of γ-rays of 12 concrete samples with and without supplementary cementitious materials, at energies of 59.5 and 661 keV. Reference [8] shows that the linear attenuation coefficients (μ) decrease with the increasing the photon energy for their concretes and the linear attenuation coefficient depends on photoelectric effect and Compton scattering at this energy.…”

Abstract-An experimental investigation of radiation shielding properties of high performance concretes (HPCs) was mad under effect of different variables. HPCs were produced from different normal and heavyweight aggregate with three low water-to-cementitious materials ratios (w/cm) to obtain different compressive strengths. The linear attenuation coefficients were measured at 0.663 MeV γ-rays energy of 137 Cs radioactive using NaI (Tl) scintillation detector. It was found that the compressive strength of heavyweight HPCs plays an important role in enhancing the attenuation of γ-rays. The compressive strength and attenuation of γ-rays have a near to linear relation. While in the normal concrete, the strength has no effect on the attenuation of γ-radiation. The mass attenuation coefficients were also compared with the values obtained by the United States National Institute of Standards and Technology (NIST). The comparison showed a reasonable agreement. It was observed that the attenuation of γ-rays is considerably affected by concrete density.Index Terms-High performance concrete, γ-attenuation coefficients, aggregate types, compressive strength, water-to-cementatious materials ratio.

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. Dierent concrete types with special cements have been prepared. The linear attenuation coecients of conventional concrete and concrete with supplementary mineral additives (barite and witherite) at dierent 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 inuence of barite and witherite additives on photon attenuation coecients of concrete.

“…Data on the attenuation of gamma-rays in matter is required for many scientific, engineering, and medical applications [1]. Many studies have recently been carried out on the attenuation coefficients for a number of materials, such as concrete [2][3][4][5], cement [5][6][7][8], glass systems [1,9,10], soil samples [11][12][13] etc. The value of the linear attenuation coefficient depends on the incident photon energy, the atomic number, and the density of the absorber.…”

The linear attenuation coefficients of water and some solid phantom materials, namely of solid water RMI-457, of plastic water, of RW3 solid water, and of Perspex were determined by Monte Carlo calculations, for gammaray photons with energies of 59.5, 80.9, 140.5, 356.5, 661.6, 1173.2, and 1332.5 keV. The calculated values were compared with the experimental results presented by other researchers and with theoretical values obtained using the XCOM database. Good agreement was observed between the calculations, the experimental, and the theoretical values. The results indicate that the process in Monte Carlo code can be followed to determine the equivalency of other materials at several energies. Three shielding factors such as half-value layer, tenth-value layer, and mean free path were calculated at all considered gamma-ray energies.
