“…Hence, concrete, being far less toxic, is the first choice in the construction of walls and flooring of radiation facilities. Although other materials such as ceramic (brick) [4] and granite [5] have been tested for their usefulness as shielding materials, their linear attenuation coefficient µ is 0.08 to 0.13 cm −1 for the 60 Co gamma ray source, which is even lower than those of the various heavyweight concrete mixtures (0.15-0.19) [6]. Hence, radioprotective shields for medical radiation facilities such as linear accelerators and for industrial gamma ray sterilization systems are constructed of concrete or concrete with an inserted iron plate.…”

We developed a new ceramic from raw material mainly composed of iron (III) oxide. The measured attenuation coefficient of the ceramic for high-energy gamma rays was in the range 0.268–0.355, which is approximately 40% of that of lead and twice that of concrete. The measured penetrating dose of the ceramic is half of that of concrete. Thus, the novel ceramic material named RASHIX may serve as a novel ceramic alternative for the wide variety of radiation shielding materials used in construction.

“…Additionally, it can be said that nano-CdO can be used as an alternative to PbO to create a more environmentally friendly shielding material. Finally, the present ceramic samples based on red clay were compared with two other materials used as a shielding material in nuclear facilities (concrete [40], and white ceramic [41]) as shown in Figure 7, where the HVL values were…”

We prepared red clays by introducing different percentages of PbO, Bi2O3, and CdO. In order to understand how the introduction of these oxides into red clay influences its attenuation ability, the mass attenuation coefficient of the clays was experimentally measured in a lab using an HPGe detector. The theoretical shielding capability of the material present was obtained using XCOM to verify the accuracy of the experimental results. We found that the experimental and theoretical values agree to a very high degree of precision. The effective atomic number (Zeff) of pure red clay, and red clay with the three metal oxides was determined. The pure red clay had the lowest Zeff of the tested samples, which means that introducing any of these three oxides into the clay will greatly enhance its Zeff, and consequently its attenuation capability. Additionally, the Zeff for red clay with 10 wt% CdO is lower than the Zeff of red clay with 10 wt% Bi2O3 and PbO. We also prepared red clay using 10 wt% CdO nanoparticles and compared its attenuation ability with the red clay prepared with 10 wt% PbO, Bi2O3, and CdO microparticles. We found that the MAC of the red clay with 10 wt% nano-CdO was higher than the MAC of the clay with microparticle samples. Accordingly, nanoparticles could be a useful way to enhance the shielding ability of current radiation shielding materials.

“…In today's world, the radiation term has become a major concern among the scientific community since artificial radiation sources have been exponentially increasing with the developing technological areas [1,2]. From medical diagnosis to industrial non-destructive tests, or from food sterilizations to communication systems the humanity has been facing with variety of irradiation including alpha, beta, gamma, or the like [3][4][5]. In fact, these rays have a strong probability of damage to human health with respect to time, exposure, and duration parameters.…”

In this study, a preliminary theoretical investigation on lithium-zinc-calcium-silicate (LZCS) glass with a composition of (15-x)Li 2 O-10ZnO-10CaO-65SiO 2 -xB 2 O 3 where x: 0, 3, 6, 9, 12, and 15 mol% was performed to understand the effect of B 2 O 3 on physical, optical, and radiation shielding properties. For this purpose, the L15B0 to L0B15 glass series was designed for evaluating glass density (ρ glass ), refractive index (n), mass attenuation coefficient (µ m ), and half-value layer (Δ 0.5 ) parameters. The theoretical calculations showed that the increasing amount of B 2 O 3 increased the overall ρ glass from 2.9195 to 2.9865 g/cm 3 . Further, the addition of B 2 O 3 in substitution for Li 2 O enhanced the n parameter from 1.6882 to 1.7626. Additionally, BatchMaker software aided to investigate viscosity behavior with the increasing temperature. We found out that the melting point of LZCS glass series ascends with the addition of B 2 O 3 , namely from 1309 to 1624 ºC. On the other hand, the newly developed Phy-X/PSD software computations paved the way for ascertaining µ m and Δ 0.5 . According to the µ m computations, one can clearly state that an increasing trend is observable against the increasing photon energy, but the L0B15 possessed an enhanced shielding ability than that of the remaining at all photon energies. Moreover, we found out that the Δ 0.5 increased with respect to the ascending photon energies, however, the Δ 0.5 was effectively improved with the addition of B 2 O 3 in the order of L0B15
