“…For example, long-term exposure to gamma radiation can lead to permanent tissue damage, acute radiation poisoning, cancer, and death in extreme cases. Thus, to prevent workers and patients who are exposed to radiation from these potential side effects, radiation shields are typically used as a protective measure [ 7 , 8 , 9 , 10 ].…”

This paper aims to study the radiation shielding characteristics and buildup factor of some types of granite in Egypt. The mass attenuation coefficient (MAC) for three types of granite (gandola, white halayeb, and red aswani) was experimentally determined, and the experimental results were validated by XCOM software. The relative deviation between the two methods does not exceed 3% in all discussed granite samples, which means that MAC calculated through the experimental and XCOM are in suitable agreement. The effective atomic number (Zeff) varies from 13.64 to 10.69, 13.68 to 10.59, and 13.45 and 10.66 for gandola, white halayeb, and red aswani, respectively. As well as the equivalent atomic number (Zeq) was calculated in a wide range of energy to deduce the exposure (EBF) and energy absorption (EABF) buildup factors for the studied granite materials. The linear attenuation coefficient (LAC), half-value layer (HVL), mean free path (MFP) were calculated at each investigated energy and showed that the most effective shielding ability at high energy was red aswani, while at low energy, the shielding ability was nearly constant for studied granites. The present study forms the first endeavor to obtain the radiation shielding properties of the studied materials to be used in practical applications.

“…However, moisture variation in concretes makes it difficult to predict radiation protection [11]. Much research is devoted to the development of glass-based radiation shielding materials [12][13][14][15][16][17][18]. The degradation of EPDM by γradiation has been extensively studied.…”

A synthetic, ethylene-propylene-diene terpolymer monomer (EPDM) rubber reinforced with carbon-black (N-220) as a filler with the addition of different concentrations of lead powder (0-500 phr), was developed to be used as a radiation shielding against  -rays. Experimental studies on the influence of -radiation on the target samples were carried out using 137 CS (E  = 0.662 Mev) and ( 60 Co with energies of 1.172 Mev and 1.332 Mev). The attenuation coefficient and HVL were improved by two ways; one way by increasing the concentration of lead powder at constant thickness and the other by increasing the thickness of the composite samples at a constant concentration of lead powder. A high attenuation coefficient and HVL was obtained for 400phr lead (μ=0.0852 and 0.141 cm -1 for Eγ = 0.662, and 1.172 Mev respectively). Good results were also obtained for HVL when using 400phr lead (HVL= 8.137, 4.915, and 5.627 cm for Eγ = 0.662, 1.172, and 1.332 Mev respectively). For testing the moderating fast neutron emitted from 239 Pu-9 Be, samples containing 100, 200, and 300 phr lead and 25 phr borax were used. The results showed good enhancement/improvement in the values of the total macroscopic cross section. As a result of using the X.com program, it was found that the values of the linear and mass attenuation coefficients were in a good agreement with the experimentation values for uniform and collimated beams. However, this could not be confirmed for heterogeneous beams.

“…However, other metal oxides can be added to their composition to improve these properties and make them viable for these uses. Metal oxides such as CaO, K 2 O, and Na 2 O act as network modifiers that help stabilize the phosphate glass so its radiation shielding properties can be tested [19,20].…”

The gamma radiation shielding ability for CaO-K2O-Na2O-P2O5 glasses were experimentally determined between 0.0595 and 1.41 MeV. The experimental MAC results were compared with theoretical results obtained from the XCOM software to test the accuracy of the experimental values. Additionally, the effect of increasing the P2O5 in the glass composition, or reducing the Na2O content, was evaluated at varying energies. For the fabricated glasses, the experimental data strongly agreed with the XCOM results. The effective atomic number (Zeff) of the fabricated glasses was also determined. The Zeff values start out at their maximum (12.41–12.55) at the lowest tested energy, 0.0595 MeV, and decrease to 10.69–10.80 at 0.245 MeV. As energy further increases, the Zeff values remain almost constant between 0.344 and 1.41 MeV. The mean free path (MFP) of the fabricated glasses is investigated and we found that the lowest MFP value occurs at the lowest tested energy, 0.0595 MeV, and lies within the range of 1.382–1.486 cm, while the greatest MFP can be found at the highest tested energy, 1.41 MeV, within the range of 8.121–8.656 cm. At all energies, the KCNP40 sample has the lowest MFP, while the KCNP60 sample has the greatest. The half value layer (HVL) for the KCNP-X glasses is determined. For all the selected energies, the HVL values follow the order of KCNP40 < KCNP45 < KCNP50 < KCNP55 < KCNP60. The HVL of the KCNP50 sample increased from 0.996 to 2.663, 3.392, 4.351, and 5.169 cm for energies of 0.0595, 0.245, 0.444, 0.779, and 1.11 MeV, respectively. The radiation protection efficiency (RPE) results reveal that decreasing the P2O5 content in the glasses improves the radiation shielding ability of the samples. Thus, the KCNP40 sample has the best potential for photon attenuation applications.
