“…Therefore, various techniques for attenuation measurements came along in different studies (Creagh and Hubbell, 1990). However, construction materials came in under light later and the attenuation coefficients of X-and g-rays in different materials were studied on a wide spread level (Atasoy et al, 1992). In some parts of the world, effects of different compositions on the shielding capabilities of building materials were investigated (Salinas et al, 2005;Singh et al, 2004).…”

“…One can see that the value of the total macroscopic cross-section in Equation (3) depends on the material’s properties and the incident neutrons through the macroscopic cross-section, which changes based on the neutron energy. Therefore, another parameter to describe the neutron attenuation called the removal cross-section ∑ R (cm −1 ), is widely used [ 4 , 42 , 43 , 44 , 45 , 46 ]. The ∑ R is the probability that a fast or fission energy neutron takes a first collision, which removes it from the group of penetrating uncollided neutrons [ 47 , 48 ].…”

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.

“…The magnitude of linear attenuation coefficients depends on the incident photon energy, the atomic number of the materials and the density (ρ) of the shielding materials [1]. Although much previous work has been performed on linear attenuation coefficients both theoretically [2,3] and experimentally [4,5] on a variety of materials, there have been only a few experimental works done on marble produced in Turkey. A work has been performed by Bashter [3] to calculate both linear (µ) and mass attenuation coefficients (µ/ρ) at photon energies of 10 keV to 1 GeV for concretes of different densities.…”

“…An experimental study has been performed by Angelone et al [4] to evaluate mass attenuation coefficients of the materials ranging in atomic number from 6 to 82 using x-rays of 13-50 keV energy. Atasoy et al [5] have performed measurements on different types of marble in Turkey using photon energies of 0.1 to 1.4 MeV. Akkurt et al performed a work to evaluate attenuation coefficients for concrete [6] and for some volcanic rocks [7].…”

The total linear attenuation coefficients micro (cm(-1)) have been obtained using the XCOM program at photon energies of 1 keV to 1 GeV for six different natural marbles produced in different places in Turkey. The individual contribution of photon interaction processes to the total linear attenuation coefficients for marble has been investigated. The calculated results were also compared with the measurements. The results obtained for marble were also compared with concrete.
