Abstract
The aim of the present study is to fabricate an economical, environmentally friendly, easily workable, light-weight and comfortable textile-based radiation shield. At first, polyester fabrics were coated with PVA resin that contained bismuth micro-particles (Bi2O3) and barium oxide (BaO) powder in two different weight ratios. Then, the fabric samples were exposed to a source of 226Ra. Attenuation characteristics such as linear attenuation coefficient (μ), half-value layer (HVL) and tenth-value layer (TVL) were calculated for the individual samples. Their morphological properties were also examined through SEM analyses. Moreover, evaluations were performed of the weight, thickness, crease recovery angle, and air permeability of the modified polyester fabrics as well as the water drop absorption time on their surface. As the results showed, the sample with 30% BaO had the highest rate of attenuation, and the attenuation coefficients would increase with an increase of barium and bismuth oxides in the samples. The lowest HVL and TVL values belonged to the sample with 30% BaO.
