properly function. Excessive exposure to ionizing radiation may lead to permanent tissue damage, acute radiation syndrome and cancer. Radiation shields are used to protect patients from these side effects, minimizing the risk involved in these procedures. A radiation shield can protect humans by absorbing the incoming photons and reducing the intensity of radiation to safe levels [1; 2]. Radiation shields can vary from metal sheets to concretes and glasses. Simple lead has historically been the most common radiation shield because its high density makes it highly effective at attenuating photons. Due to its toxic nature, its use should be restricted as much as possible, especially in medical treatment facilities. Therefore, researchers have been studying environmentally friendly substitutes to lead that are just as effective [3; 4; 5]. Concrete is a great candidate for this cause because of its low cost, simple manufacturing, and wide range of composition. The elements that typically compose concrete are often effective attenuators themselves, improving the properties of the material. Even though concrete is used as a radiation shield, it is prone to cracking and water loss over time, leading researchers to seek an alternative [6; 7]. Radiation shielding glasses have similar benefits to concretes, except they offer the additional benefit of being transparent. Transparency can be useful to have the ability to view the adjacent room and allows the glasses to be used in non-medical applications as well [8; 9]. Metal oxides, and heavy metal oxides especially, can alter the characteristics of the glass to fit its application. Metal oxides are broken up into three categories: glass formers, glass modifiers, and glass intermediates. Glass formers form the backbone of the glass network, glass modifiers alter the network but not the backbone, and intermediates can have the properties of each depending on the constituents of the glass [10; 11; 12; 13]. Radiology uses average energies of 20 keV (dental), 30 keV (mammography), 40 keV (general), and 60 keV (computed tomography), respectively. Since these energies are the typically energy levels of photons used in the medical field, the glasses in this study will be examined under these energy ranges [14]. To evaluate the radiation shielding properties of glasses, researchers calculate and analyze several parameters. The typical method for obtaining these parameters is through an experimental study. To check the accuracy of the experiment, simulations are often used. Additionally, simulations also serve as an alternative method to investigate radiation shielding materials when it is not possible or practical to conduct actual experiments, such as during the COVID-19 pandemic. Previous studies have demonstrated the reliability of using simulations for shielding evaluations. MCNP-5 and Geant4 are two examples of simulation codes that use the Monte Carlo method [15; 16; 17; 18; 19; 20; 21; 22]. It is good to note that the quality of data produced by modern simulation codes is limited to the quality of the embedded data libraries [23]. Electron Photon Interaction Cross Sections 2017 (EPICS2017) was released online by IAEA in 2018 [24; 25]; it is the official electron-photon collection of ENDF/B-VIII [26]. The EPICS2017 is designated to replace all preceded electron and photon data embedded in the simulation codes.
