“…The nuclear shielding efficiency of the tested rocks was investigated by using the EPICS2017 library. EPICS2017 was found to be a useful method for the evaluation of the mass attenuation coefficients for different materials [ 26 , 27 , 28 , 29 , 30 ]. Previously, Obaid et al [ 26 ] used Monte Carlo simulation via MCNPX and Geant4 to report the μ/ρ values and other parameters for some of the investigated rocks in this work.…”

“…Moreover, Obaid et al [ 6 , 7 ] used an experimental method to report the radiation attenuation factors for some of the investigated rocks in this study. The novelty in this work is that we used the same rocks reported in [ 6 , 7 , 26 ], but we used another technique, namely the EPICS2017 library, and reported the μ/ρ values and other factors. The aim with this work was to check the possibility of using the EPICS2017 library to calculate the μ/ρ, HVL, etc., for some rock samples, and thus to find an alternative technique to evaluate the radiation attenuation abilities for any rocks.…”

Radiation leakage is a serious problem in various technological applications. In this paper, radiation shielding characteristics of some natural rocks are elucidated. Mass attenuation coefficients (µ/ρ) of these rocks are obtained at different photon energies with the help of the EPICS2017 library. The obtained µ/ρ values are confirmed via the theoretical XCOM program by determining the correlation factor and relative deviation between both of these methods. Then, effective atomic number (Zeff), absorption length (MFP), and half value layer (HVL) are evaluated by applying the µ/ρ values. The maximum μ/ρ values of the natural rocks were observed at 0.37 MeV. At this energy, the Zeff values of the natural rocks were 16.23, 16.97, 17.28, 10.43, and 16.65 for olivine basalt, jet black granite, limestone, sandstone, and dolerite, respectively. It is noted that the radiation shielding features of the selected natural rocks are higher than that of conventional concrete and comparable with those of commercial glasses. Therefore, the present rocks can be used in various radiation shielding applications, and they have many advantages for being clean and low-cost products. In addition, we found that the EPICS2017 library is useful in determining the radiation shielding parameters for the rocks and may be used for further calculations for other rocks and construction building materials.

“…Poon et al [36] carried out a validation specifically for water and tungsten in the 1 keV -100 MeV energy range for radiotherapy physics applications. Furthermore, some studies compared simulated results based on Livermore models with XCOM data and experimental data for specific energy values, using radioactive sources in the keV -MeV energy range, for typical biological, geological and industrial materials [37][38][39]. All these publications have highlighted the applicability of the Livermore models.…”

“…One of the most commonly used gamma rays is used in nuclear research centers, radiotherapy and medical equipment sterilization. Medical professionals, patients, and others who come into contact with gamma photon sources need to be protected from the harm that these photons can cause [1][2][3]. Radiation-protection materials have been developed using a wide range of novel materials, including lead and concrete.…”

Glass samples with (86-x)TeO2 – 12Nb2O5- x(Ta2O5) -1.0La2O3 where 𝑥 = 1.0 (glass TNTL1), 5.0 (glass TNTL2), 8.0 (glass TNTL3), and 10 (glass TNTL4) mol% composition were synthesized by a melt quenching technique. The gammaray attenuation parameters of TNTL system such as MAC, LAC, HVL, MFP, Zeff, and Neff were analyzed in this study in order to better understand the effect of Ta2O5 on photon absorption.Within the 190-2500-nm wavelength range, the optical properties of prepared TNTL glasses were also evaluated. It was observed from the optical absorption spectra that all glass samples studied had good optical transparency. The findings indicated that adding Ta2O5 to glass enhances the gamma protection ability as well as the optical properties. The densities of the samples ranged from 5.66 to 6.49 g/cm3, depending on the Ta2O5 concentration. Sample TNTL4 had the best preformace, according to the results recorded.
