“…Comparisons of simulated mass attenuation coefficients using MCNP codes are described in Tables 4 and 5. In Table 4, comparative results are shown between EPICS2017 interpolated results versus MCNP5 simulations, for several PbO-and Bi 2 O 3 -influenced glasses taken from Sayyed et al 2020 [27]. This comparison is made in a broad energy range of 15 keV to 15 MeV.…”

In this paper, the investigation of the Electron–Photon Interaction Cross Sections 2017 (EPICS2017) library on the shielding characteristics of several glasses under various chemical systems is presented. The EPICS2017 library of ENDF/B-VIII was interpolated to calculate the mass attenuation coefficients (MACs) of selected glass systems. Results from EPICS2017 have been compared with values from experimental and theoretical methods used to evaluate the photon shielding properties. The EPICS2017 estimations strongly agreed with experimental MAC results. The MAC values from several Monte Carlo codes (Geant4, MCNP4C, MCNP5, and FLUKA) based on EPDL97 or EPDL89 strongly agreed with EPICS2017-based interpolation, within reasonable deviations. The obtained results indicate that EPICS2017 can be used to evaluate the MACs for any glass system in which there are no experimental values available at various photon energies. It was demonstrated that the linear EPICS2017 library can be a considerable tool in future photon shielding research and developments of glass systems, as a recent alternative to the widely used XCOM by NIST.

“…Monte Carlo N Particle Transport Code (MCNP5) is a computer algorithm based on random sampling, and is well-accepted as one of the simplest methods to assess the radiation shielding performance of materials. [26][27][28] The radiation source is defined by inputting the type, energy, geometric position, and incident direction of incident particles, which are tracked by probability statistics. After a particle passing through the transmission plane, it stops tracking and starts to simulate the next particle until all the particles are simulated.…”

Lead‐containing plexiglass is prepared successfully via copolymerization of lead‐methacrylate (Pb(MAA)2 and the acrylic monomer such as methyl methacrylate, methyl acrylate, ethyl acrylate, and butyl acrylate. The results show that as‐prepared plexiglass has good photons shielding performance and resistance to the discoloration induced by radiation (10 kGy γ‐ray), and the alteration of shielding performance can be well described by the Monte Carlo Code simulations (MCNP5). Using two plasticized systems, the external‐plasticized one with various n‐octanoic acid concentrations and the internal‐plasticized one with different acrylic monomer, as the target samples, it is found that free volume plays dominant role in the irradiation resistance via the positron annihilation lifetime spectroscopy and electron paramagnetic resonance characterizations. The larger the free volume, the greater the quenching probability of free radicals during irradiation. Because the primary type of radiation‐induced color centers are annealable color centers, the effect of annealing of irradiation‐induced discoloration of lead‐containing plexiglass is remarkable. Differing from common treatments of improving irradiation resistance, the increased free volume via plasticization gives plexiglass good resistance to discoloration. This study discloses valuable information around improving irradiation shielding performance and resistance to the radiation‐induced discoloration for the plexiglass‐based materials.
