The X-ray attenuation and the flexural properties of lead-free coated fabrics

Abstract

In this paper, tungsten, bismuth, tin, and copper powders were used as additives in the fabric coating to obtain lead-free and flexible x-ray shielding material. The X-ray attenuation and the flexural properties of the coated fabrics were investigated considering the medical protection requirements. The results showed that tungsten additives in silicone rubber coating had better attenuation ratios than the samples that contain tungsten-tin, bismuth, and tungsten-copper, at same additive volume ratios. Moreover, the increment of tungsten volume ratios in coating blend resulted in higher shielding performance at same effective thicknesses and the lower silicone rubber amount in coating lead to compose thinner and lighter fabrics for equal protection level. In addition to that, the samples with tungsten-tin, bismuth, and tungsten-copper showed remarkable attenuation properties, and the results were found to be coherent with the theoretical values. The flex resistance and the flexural rigidity of the samples with tungsten content were also investigated. The coated fabrics with different powder loadings and thicknesses showed good resistance against repetitive folding; on the other hand, the results showed that the increment of tungsten amount in the coating resulted in stiffer fabrics.

Construction of a Medical Radiation-Shielding Environment by Analyzing the Weaving Characteristics and Shielding Performance of Shielding Fibers Using X-ray-Impermeable Materials

“…This method has the disadvantage of not imparting the inherent properties of the fibers to the fabric because of their low flexibility and high rigidity [37][38][39]. In addition, it is difficult to reproduce the shielding performance because the shielding performance must be controlled by adjusting the coating thickness during the process [40,41].…”

Material characterization and Monte Carlo simulation of lead and non-lead X-Ray shielding materials

“…The generated compositions and the commercial material compositions, which were determined by material characterization methods, were simulated under the same conditions via MC simulator. The hypothetical compositions were devised with the purpose of applicability as coating on textile surfaces similar to the studies (Aral et al 2016, Aral et al 2017) in which silicone rubber with tungsten, bismuth, tin, barium sulphate powders were applied on fabrics to design novel wearable x-ray protective materials. In this study, three new compositions with the content of silicone rubber, bismuth, and tin were generated to compare their X-ray attenuation behaviors with commercial samples which also would have potential to be used in future experimental studies.…”

“…For the generated compositions, silicone rubber (dSR: 1.11 g/cm 3 ) was chosen as the polymer which was also used in previous experimental studies (Aral et al, 2016, Aral et al, 2017 because of its compatibility to the cotton surfaces that form strong adhesion.…”

Investigation of Shielding Parameters to Fabricated Shields From Polymer With Nano-Barium Oxide Materials

The MAC) μ/ρ (is a measurement of the mean proportion of interactions between radiation which is incoming and materials that can place in a particular mass-per-unit area width of the contacted materials [5][6][7][8]. A unique atomic number is a property of an element but does not accurately characterize the atomic number of a composite material in all energy levels due to the photon interaction cross-section for elements of the composite material.…”
