Objective (s): Recently, the use of nanoparticles in medicine has increased for radiation protection purpose. So the aim of this study was application of nano Bi2O3 in prepared shield for dose reduction during medical imaging.Materials and Methods: Nano Bi2O3 shield with 90 silicon and 10 nano Bi2O3 was prepared and dosimetry test was down in radiology by PTW DIADOS E dosimeter.Results: The mean dose without using nano Bi2O3 shields were 421 µGy, 733 µGy and 1110 µGy for 60, 80 and 100 kVp , respectively. After using 0.5 mm thickness of nano Bi2O3 shield dose reduction in 60, 80 and 100 kVp was 42, 35 and 31. A comparison between increasing energy from 60 to 100 kVp and dose reduction showed a significant reverse effect.Conclusion: The results indicate that the new shields containing nano Bi2O3 particles have a high X-rays attenuation ability but the attenuation property of the shields was decreased by the increasing of the energy. Based on the results, this new shield can help social health and decline the radiation risk.
