“…7 Percentage X-ray attenuation of the matrix and G1-25, G1-2.5, G2-25 and G2-2.5 nanocomposite blocks as a function of X-ray photon energy attenuation as the material under consideration under similar conditions of irradiation (Nambiar et al 2013;Scuderi et al 2006). Thus, it is a standard reference for non-lead shielding material (Nambiar et al 2013;Scuderi et al 2006). The lead equivalence of nanocomposites containing G1 and G2 nanoparticles (25 wt%) at X-ray photon energy of 40 keV is found to be 0.094 and 0.08 mm, respectively.…”

“…Ambika et al (2016) have studied the gamma shielding property of unsaturated polyester resin-based nanocomposite containing bismuth oxide nanoparticles, with a shielding ability comparable to that of barite at low energies of gamma rays. Scuderi et al (2006) have studied the radiation protection efficacy of commercially available non-lead-based radiation protective garments such as Xenolite, EarthSafe and Demron against X-rays of energy 60-120 keV. In their study, Demron is found to exhibit better attenuation than EarthSafe and Xenolite.…”

In an attempt to develop an alternate to leadbased X-ray shielding material, we describe the X-ray attenuation property of nanocomposites containing Gd 2 O 3 as nanofiller and silicone resin as matrix, prepared by a simple solution-casting technique. Gd 2 O 3 nanoparticles of size 30 and 56 nm are used at concentrations of 25 and 2.5 wt%. The nanoparticles and the nanocomposites are characterized using X-ray diffraction (XRD) studies, small angle X-ray spectroscopy (SAXS), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and atomic force microscopy (AFM). The X-ray attenuation property of nanocomposites, studied using an industrial X-ray unit, shows that nanocomposites containing nanoparticles of size 56 nm (G2) exhibit better attenuation than nanocomposites containing nanoparticles of size 30 nm (G1), which is attributed to the greater interfacial interaction between the G2 nanofillers and silicone matrix. In the case of nanocomposites containing G1 nanoparticles, the interfacial interaction between the nanofiller and the matrix is so weak that it results in pulling out of nanofillers, causing voids in the matrix, which act as X-ray transparent region, thereby reducing the overall X-ray attenuation property of G1 nanocomposites. This is further corroborated from the AFM images of the nanocomposites. The weight loss and heat flow curves of pure silicone matrix and the nanocomposites containing Gd 2 O 3 nanoparticles of size 30 and 56 nm show the degradation of silicone resin, due to chain scission, between 403 and 622°C. The same onset temperature (403°C) of degradation of matrix with and without nanoparticles shows that the addition of nanofillers to the matrix does not deteriorate the thermal stability of the matrix. This confirms the thermal stability of nanocomposites. Therefore, our study shows that nanocomposites containing G2 nanoparticles are potential candidates for the development of X-ray opaque fabric material.

“…The radiopacity should be evaluated under similar conditions to those used during the clinical procedure (60-130kV, 3.2-10mAs [60]) and compared to a control, such as PMMA formulations designated for use in vertebroplasty. Aluminium scales should be X-rayed simultaneously to the specimens and the radiopacity should be expressed in mmAl, for easier comparison between studies.…”

Currently available treatments for the degenerated intervertebral disc present disadvantages, such as surgical invasiveness and inadequate load distribution results. Load-bearing, injectable materials may be interesting for future therapies, but have not been studied in depth.In this study, the existing literature was screened for studies on injectable materials for the intervertebral disc and a rationale for load-bearing, injectable materials was formulated.Requirements for such a material were discussed, partly based on the experience of materials used for similar applications. Important properties were discussed and found to include biocompatibility, bioactivity, porosity, handling, injectability, working time, setting time, radiopacity, containment and mechanical properties, where several of these properties are linked to one another.Load--bearing injectables for the disc 2In conclusion, there is a need for consensus on the properties of new materials developed for use in minimally invasive procedures in the spine. A substantial amount of attention may need to be given to non-toxic setting reactions.
