Design and Gamma-Ray Attenuation Features of New Concrete Materials for Low- and Moderate-Photons Energy Protection Applications
We aimed, in this investigation, to prepare novel concretes which can be used in gamma-ray shielding applications. The experimental approach was performed using a NaI (Tl) detector to measure the concrete’s shielding features for different energies, ranging from 0.081 MeV to 1.408 MeV. The density o...

| description | We aimed, in this investigation, to prepare novel concretes which can be used in gamma-ray shielding applications. The experimental approach was performed using a NaI (Tl) detector to measure the concrete’s shielding features for different energies, ranging from 0.081 MeV to 1.408 MeV. The density of the fabricated concretes decreased with increasing W/C ratio, where the density decreased by 2.680 g/cm<sup>3</sup>, 2.614 g/cm<sup>3</sup>, and 2.564 g/cm<sup>3</sup> for concretes A, B, and C, respectively, with increases in the W/C ratio of 0.4, 0.6, and 0.8, respectively. When the energy was elevated between 0.08 MeV and 1.408 MeV, the highest values were attained for concrete A, with values ranging between 0.451 cm<sup>−1</sup> and 0.179 cm<sup>−1</sup>. The lowest half-value layer (Δ<sub>0.5</sub>) values were achieved for concrete C, where the Δ<sub>0.5</sub> values varied between 1.53 cm and 3.86 cm between 0.08 MeV and 1.408 MeV. The highest Δ<sub>0.5</sub> values were achieved for concrete A, where the Δ<sub>0.5</sub> varied between 1.77 cm and 4.67 cm between 0.08 MeV and 1.408 MeV. According to this investigation, concrete A has the highest promise in radiation shielding purposes because it has the most desirable properties of the concretes studied. |
