Production of Barite and Boroncarbide Doped Radiation Shielding Polymer Composite Panels

Abstract

Developments in nuclear technology in the last century have lead to the use of radiation in different areas of human activity. These are not just the energetics but also food, agriculture, medicine, industry and science. Thus, radiation has become an inevitable phenomenon in our lives. Since we cannot isolate radiation from our life, the radiation protection methods should be available. As alternatives to conventional radiation prevention methods, such as lead and heavy concrete shielding, more functional materials need to become the focus of research. The development of the least harmful to the environment, easily applicable, flexible radiation shields has become very important. In this study, silicon matrix composite panels, doped with different ratios of barite and boron carbide, were produced and characterized by optical and scanning electron microscopy (SEM). Gamma and neutron radiation shielding properties of these materials were investigated. The results have been compared with the lead as the standard shielding material.

Evaluation of boron waste and barite against radiation

“…As shown in Fig. 6 (Dinçer 2018;Strydom et al 1995). Figure 6 shows that patterns of pure barite powders are present in the XRD patterns, similar to the results from the literature (Evcin et al As shown in Table 3 and Fig.…”

Polymeric composite materials for radiation shielding: a review

“…Graphite/epoxy composite showed the highest performance in gamma radiation attenuation among epoxy/graphite, epoxy/lead, and epoxy/boron (Saiyad et al 2014 ). A proportional relationship between photon attenuation coefficients and barite concentration was revealed when barite and boron carbide-doped radiation shielding polymer composite was prepared for radiation shielding (Evcın et al 2017 ). Blended powdered polyethylene glycol and lead oxide prepared by physical mixing revealed that the shielding properties of polyethylene glycol increased with the addition of lead oxide (Hussain et al 1997 ).…”

Analysis of the Correlation between Shielding Material Blending Characteristics and Porosity for Radiation Shielding Films

“…Now, they are very important factors for the processability of an RSF. The durability and organization between a shield material and the process technology have been studied [17,18]. For RSFs in the industrial field, an important condition for the safe transfer of contaminated substances after the Fukushima incident in Japan was that the minimum strength should support the weight.…”
