“…Research on RSC with a cathode-ray tube as the aggregate used 62 kg/m 3 of fly ash, which constituted 14.9% of the total binder content [ 65 ]. Another study on RSC with recycled concrete as the aggregate used 798 kg/m 3 of fly ash, which is 64% of the total binder content [ 66 ]. The study also used ground granulated blast furnace slag as the binder, the amount varying from 179–283 kg/m 3 , which is 14–21% of the total binder content.…”

“…A comparison among samples with a natural aggregate also indicates the influence of aggregate sizes on the radiation shielding efficiency. A sample with a coarse-to-fine aggregate ratio of 1.6 had a higher μ compared with samples with a coarse-to-fine aggregate ratio of 0.8–1.18 [ 29 , 66 , 123 ]. This result may be due to the higher surface area of a fine-sized aggregate compared with that of a coarse aggregate, which created a larger interfacial transition zone.…”

Nuclear energy offers a wide range of applications, which include power generation, X-ray imaging, and non-destructive tests, in many economic sectors. However, such applications come with the risk of harmful radiation, thereby requiring shielding to prevent harmful effects on the surrounding environment and users. Concrete has long been used as part of structures in nuclear power plants, X-ray imaging rooms, and radioactive storage. The direction of recent research is headed toward concrete’s ability in attenuating harmful energy radiated from nuclear sources through various alterations to its composition. Radiation shielding concrete (RSC) is a composite-based concrete that was developed in the last few years with heavy natural aggregates such as magnetite or barites. RSC is deemed a superior alternative to many types of traditional normal concrete in terms of shielding against the harmful radiation, and being economical and moldable. Given the merits of RSCs, this article presents a comprehensive review on the subject, considering the classifications, alternative materials, design additives, and type of heavy aggregates used. This literature review also provides critical reviews on RSC performance in terms of radiation shielding characteristics, mechanical strength, and durability. In addition, this work extensively reviews the trends of development research toward a broad understanding of the application possibilities of RSC as an advanced concrete product for producing a robust and green concrete composite for the construction of radiation shielding facilities as a better solution for protection from sources of radiation. Furthermore, this critical review provides a view of the progress made on RSCs and proposes avenues for future research on this hotspot research topic.

“…Several authors have analyzed the factors influencing the radiation shielding for different concrete densities [2][3][4] and for the incorporation of some typical heavy natural aggregates such as barite, magnetite, goethite, serpentine, hematite, ilmenite or limonite [5][6][7][8] . The use of aggregates of a different nature such as galena [9], synthetic aggregates [10], recycled coarse aggregates [11] and steel slags [12] in HDSC can also be found. In general, the influence on radiation shielding of the type of aggregate is greater than its quantity [13].…”

“…Monte Carlo technique that considered as a powerful and reliable computational tool, was used in many studies regarding the characterization of several shielding materials [7][8][9][10][11][12]. In the present work, a computer simulation program based on Monte Carlo method was written to be as virtual experimental system, instead of the real experimental system, concerning evaluation of attenuation properties for studied glass materials.…”

This work aims to introduce an useful computational model, based in Monte Carlo simulation, which can be used in practical application, and this paper presents values determined using a Monte Carlo algorithm for linear attenuation coefficient of lead zinc borate glasses with different percentages of PbO. The simulation results have been verified with predictions from the XCOM program in the studied energy region from 1 keV to 2000 keV and experimental results. Thus, this verification indicated that this research method can be followed to determine the interaction and attenuation of gamma rays with the several energies in different materials. Also, the values of mean free path and the half-value layer were calculated using the values of the linear attenuation coefficient. The dependence of these radiation shielding parameters on the energy of impinging gamma ray and the ratio of substances changes has been examined.
