Determination of radiation attenuation coefficients of heavyweight- and normal-weight concretes containing colemanite and barite for 0.663MeV γ-rays

Investigation of photon attenuation coefficient of some building materials used in Turkey

“…The chemical composition of these materials, which were necessary input for XCOM calculations, was referred from literature [2][3][4][5]7].…”

“…Radiation shielding materials are investigated for their shielding properties through linear attenuation coefficient being defined as the probability of interaction of radiation with matter in unit path length [1]. In literature building materials were studied by many scientists in terms of their gamma shielding properties [2][3][4][5]. Concrete is commonly used building material in Turkey.…”

Effect of Compressive Strength on γ-Radiation Attenuation Coefficients for High Performance Concrete

“…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 [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. It was concluded that barite was effective at 0.663 keV.…”

“…[6], [7]. Overall, heavyweight concrete has been used where it is necessary to reduce the thickness of radiation shielding, generally because of space considerations [8]- [13]. According to Lee,et al [14] the aggregate of concrete plays an essential role in modifying physical-mechanical properties of concrete; it also affect significantly shielding properties of concrete [2], [6], [15].…”
