| description | The aim of this study is to investigate the radiation shielding properties of novel concrete samples with bulk Bi<sub>2</sub>O<sub>3</sub> and Bi<sub>2</sub>O<sub>3</sub> nanoparticles (Bi<sub>2</sub>O<sub>3</sub> NP) incorporated into its composition. The mass attenuation coefficient of the concrete samples without Bi<sub>2</sub>O<sub>3</sub> and with 5 and 7 wt% bulk Bi<sub>2</sub>O<sub>3</sub> were experimentally determined and were compared against values obtained using the XCOM and Geant4 simulations. Both methods greatly agree with the experimental values. The linear attenuation coefficients (LAC) of blank concrete (C-0), concrete with 5% bulk Bi<sub>2</sub>O<sub>3</sub> (C-B5), and concrete with 5% nanoparticle Bi<sub>2</sub>O<sub>3</sub> (C-N5) were determined and compared at a wide energy range. We found that the LAC follows the trend of C-0 < C-B5 < C-N5 at all the tested energies. Since both C-B5 and C-N5 have a greater LAC than C-0, these results indicate that the addition of Bi<sub>2</sub>O<sub>3</sub> improves the shielding ability of the concretes. In addition, we investigated the influence of nanoparticle Bi<sub>2</sub>O<sub>3</sub> on the LAC of the concretes. The half-value layer (HVL) for the concretes with bulk Bi<sub>2</sub>O<sub>3</sub> and Bi<sub>2</sub>O<sub>3</sub> nanoparticles is also investigated. At all energies, the C-0 has the greatest HVL, while C-N15 has the least. Thus, C-N15 concrete is the most space efficient, while C-0 is the least space efficient. The radiation protection efficiency (RPE) of the prepared concretes was found to decrease with increasing energy for all five samples. For C-0, the RPE decreased from 63.3% at 0.060 MeV to 13.48% at 1.408 MeV, while for C-N15, the RPE decreased from 87.9 to 15.09% for the same respective energies. Additionally, C-N5 had a greater RPE than C-B5, this result demonstrates that Bi<sub>2</sub>O<sub>3</sub> NP are more efficient at shielding radiation than bulk Bi<sub>2</sub>O<sub>3</sub>. |
