“…Radiation shielding can be done by using materials of special categories which are made by using compounds of lead, tungsten, rare earths, barium, bismuth, etc. [1][2][3]. Hajime Monzen et al investigated the estimation of the shielding ability of a tungsten functional paper for diagnostic X-rays and gamma ray [4].…”

We report a novel chemical method for the development of advanced lead free, multiconstituent-based composite materials for shielding against diagnostic X-rays by exploring the multi-elemental, multi-componential phases inherently present in red mud and brine sludge. The chemical treatment of red mud with citric acid and further using brine sludge leads to formation of two types of powders, tailored radiation shielding powder & advance tailored radiation shielding powder. The synthesised shielding powders were characterised by using various techniques like FTIR, TGA, DSC, FESEM, XRD and EDS. The synthesized powders have high-density, multi-layered, multicrystaland multi-shielding phases necessary for imparting radiation shielding properties. The shielding at different energies of X-ray photons for developed advanced radiation shielding panels and tiles has been calculated. The developed advanced lead free, multiconstituent-based composite materials can be used in broad application spectrum ranging from diagnostic X-ray and CT scanner room to other strategic radiation shielding installation.

“…The basic characteristics of ordinary concrete and heavy-weight concrete with barite were studied for the case of their use for shielding from gamma radiation [1,2,3]. In cost-benefit analysis the question is what are the radiation characteristics of different types of concrete, which could be used to protect against gamma and X rays [4,5,6]. 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.…”

“…Investigations in these references [8,9] is designed to, by simultaneously using different portions of the two materials, nano-silica and barite, in the composition of various types of concrete conduct tests on the ability to improve the mechanical properties and properties for the radiation protection of concrete. In this paper, computer code XCOM [10] was used for the calculation of the total mass attenuation coefficients (μ/ρ)tot, which is an important factor for determination of the photon attenuation, as well as during research and testing of radiation protection properties [1][2][3][4][5][6] for different content of aggregates in concrete. Computer code XCOM operates on a method of combining the values of the existing database for effective cross section of physical processes accompanying the transport of photons through different materials.…”

This paper presents a method of numerical calculations of the total mass attenuation coefficient as one of the basic radiation characteristics of materials used for produced of concrete for a special purpose. Using the XCOM software, numerical calculations were made, and then the results between the mass attenuation coefficient values for the selected type of concrete with barite, for concrete which are a combination of steel with magnetite and steel with limonite, and for UHPC concrete with barite and nanosilica, are compared.

In this study, the effect of boric acid addition on the microstructure of gypsum plaster was investigated to determine an environmentally friendly gypsum additive that may enhance mechanical strength, fire resistance, and X-ray radiation attenuation properties. The mechanical strengths of bare gypsum and boric acid-added (0–0.5% by weight with respect to gypsum amount) gypsum plasters were evaluated in terms of compressive and bending strengths. The effects of the different addition procedures of boric acid (0.1% by wt.) on the fire resistance of the gypsum plasterboard were also evaluated. X-ray radiation attenuation properties of boric acid-added (0.1% by wt.) gypsum plasterboard were investigated as well. XRD, ATR-FTIR, Helium pycnometer, N2 adsorption–desorption, and SEM analysis were performed to determine the microstructural properties of gypsum plaster. XRD and ATR-FTIR analysis revealed that boric acid did not change the calcium sulfate dihydrate structure of gypsum plaster. Whereas, Helium pycnometer, N2 adsorption–desorption, and SEM analysis showed that the physical properties of gypsum changed with an increase in pore volume, skeletal density, and particle size after boric acid addition. The increase in the pore volume and particle size decreased the mechanical strength of gypsum. However, boric acid addition on the gypsum plaster plate, especially using the spraying method, enhanced the fire resistance of gypsum. Additionally, boric acid slightly enhanced the X-ray radiation attenuation properties (0.7%) of the gypsum plasterboard.
