- Page : In this study, a jelly-type radiation shielding material was developed by combining polyvinyl alcohol (PVA), which provides excellent processability and reproducibility, with bismuth, a material known for its superior radiation attenuation properties. The shielding effectiveness against primary and scattered radiation, as well as the impact on image quality, were evaluated, and its performance was compared with that of a conventional barium-based shield to assess clinical applicability. Dose and image quality assessments were conducted using simple radiography with a head phantom and CT examinations with a CTDI phantom, followed by statistical analysis of the results. In simple radiography, the PVA-bismuth shield achieved a maximum dose reduction of 36.42%, while no statistically significant differences were observed in image quality indices (SNR and CNR) before and after shielding (p > 0.05). In CT examinations, the scattered dose reduction reached 92.38%, with no significant differences in SNR values (p > 0.05), indicating that image quality was preserved. Overall, the PVA-bismuth-based jelly-type shielding material demonstrated lightweight, conformability, processability, and cost-effectiveness, and quantitative as well as statistical analyses verified its excellent shielding performance and suitability for clinical application.
