“…Cube moulds were filled with these mixtures and kept for 48 h in a casting room at a temperature of 25˚C after which they were demoulded. The prepared ten samples were named as IS 0 , IS 1 , IS 2 , IS 3 , IS 4 , IS 5 , IS 6 , IS 7 , IS 8 and IS 9 . A Pure flyash sample is also prepared for comparing results.…”

Using steel slag and two types of (soft and hard) iron slags, ten samples were prepared. Different gamma radiation interaction parameters were computed theoretically and measured experimentally at different energies: 60 keV, 136 keV, 662 keV, 1173 keV and 1332 keV in low and medium energy range using narrow transmission geometry. It has been observed that shielding effectiveness of a sample is inversely proportional to Half Value Layer (HVL). The obtained results were compared with Pure Flyash and it was observed that slag is better aggregate than flyash in shielding radiation as well as in construction applications. The results have been presented in the form of tables and graphs with more useful conclusions.

“…The accurate determination of interaction parameters is essential before a given material is used in any field. Mass attenuation coefficient [2]- [9] is the basic parameter for understanding the gamma ray interaction with matter. It gives fraction of the energy scattered or absorbed due to interaction with matter.…”

“…As the XCOM code uses the chemical properties of the volcanic rocks, they were obtained by X-ray fluorecence [7] and the results are tabulated in Table 1. The measurements as detailed elsewhere [8] have been performed using 0.1 µCi activity of 60 Co source which emits 1.33 MeV γ-rays. If N and N o are the measured count rates in G-M respectively with and without the absorber of thickness x(cm) the linear attenuation coefficients (µ) can be extracted by the standard equation:…”

The linear attenuation coefficient (µ cm −1 ) of photon propogation and the thermal conductivity have been determined for some volcanic rocks, which are commonly used materials in building constructions especially as a cladding stone. The linear attenuation coefficient calculated using XCOM is compared with the measurement. Thermal conductivity has been extracted from P-Wave velocity measured using a Pundit apparatus. The relation between thermal conductivity and the attenuation coefficient are also investigated.

“…The most important quantity characterizing the penetration and diffusion of gamma radiation in extended media is the attenuation coefficient, µ [7,[9][10][11][12][13]. This quantity depends on the photon energy E and on atomic number Z of the medium.…”

Nuclear facilities as nuclear power stations, nuclear research reactors, particle accelerators and linear accelerator in medical institution using concrete in building construction. The different type materials of the aggregate as component of concrete were analyzed to provide radiation protection. The energy deposited the transmission factor and the mass attenuation coefficients in ordinary and barite concretes have been calculated with the photon transport Monte Carlo software. The numerical simulations results show that using barite as an aggregate in the concrete is one of the solutions for gamma ray shielding. Thereat, it is shown non-destructive method for determining the gamma radiation absorption characteristics of concrete.
