“…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.…”

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.

“…Recently, Al-Buriahi et al [7] studied the gamma, neutron, and charged particle interaction with DNA nucleobases using the FLUKA code. In the literature, gamma and neutron interaction parameters were studied for glasses [8][9][10], inorganic compounds [11][12][13][14], polymers [15][16][17], concretes [18], tissue equivalent materials [19][20][21][22], biomolecules [23], and alloys [24][25][26]. So, the authors of this paper have found a gap in the literature where the gamma and neutron interaction parameters were not estimated for DNA and RNA (ribonucleic acid) nucleotides.…”

In this study, the gamma and neutron interaction parameters of deoxyribonucleic acid and ribonucleic acid nucleobases such as adenine, cytosine, guanine, thymine, and uracil were estimated and compared to those of water. The present calculated mass attenuation coefficient values of deoxyribonucleic acid nucleobases were compared with available simulation code values. From the data, it is observed that guanine has the highest linear attenuation coefficient values among the nucleobases and water in the energy region from 0.015 to 15 MeV. Uracil has a higher effective atomic number and equivalent atomic number values than other nucleobases in the energy region from 0.015 to 15 MeV. Among the nucleobases, uracil has lower buildup factor values, up to 200 keV. However, up to 200 keV, uracil has higher buildup factor values than water. The mass attenuation factor values for nucleobases are listed in the following order: thymine > cytosine > adenine > uracil > guanine. It has been discovered that as the mass attenuation factor increases, the hydrogen wt% of nucleobases also increases.

“…An essential parameter for radiation shielding in a material is the attenuation efficiency (% reduction in flux) compared to incident radiation. The attenuation of the neutrons in the shielding materials changes based on the neutron energy and the microstructure of the shielding material [ 22 , 23 ], which for thermal neutrons is referred to as the macroscopic thermal neutron cross-section attenuation. In contrast, for fast neutrons, this is referred to as the macroscopic effective removal cross-section [ 24 , 25 , 26 ].…”

Assessment of Five Concrete Types as Candidate Shielding Materials for a Compact Radiation Source Based on the IECF

A radiation source based on the inertial electrostatic confinement fusion (IECF) system is being developed for multidisciplinary research applications. The radiation outputs from the IECF system are 2.45 MeV fast neutrons and the associated co-generated X-rays with an energy less than 3 MeV. A radiation shielding study has been performed on five types of concrete to define the most efficient material for the shielding design of the system. The proposed materials were ilmenite-magnetite concrete (IMC), ordinary concrete-1 (OC-1), barite-containing concrete (BC), ordinary concrete-2 (OC-2), and serpentine-containing concrete (SC). A numerical model was applied to determine the effective removal cross-section coefficients (∑Rt) for the fast neutrons and the total mass attenuation coefficients (µm), the half-value layer (HVL), the mean free path (MFP), the effective atomic number (Zeff), and effective electron density (Neff) for photons inside the materials. The model considered the radiation source energy and the material properties of the concrete types. The results revealed that the serpentine-containing concrete exhibited the highest ∑Rt with 12 cm of concrete thickness needed to attenuate an incident neutron flux to 1/100 of its initial value. In addition, the BC shows the highest µm with a 38 cm concrete thickness needed to attenuate the 3 MeV energy X-ray flux to 1/100 of its initial value. This study suggests that a 40 cm thickness of SC or BC adequately shields the radiation generated from an IECF system with a maximum particle production rate of up to 1 × 107 n/s.
