Abstract
ABSTRACT In radiology, radiation shielding is important for protection especially with diagnostic radiation, such as diagnostic X-ray, because radiation exposure can damage cellular DNA. Currently, lead is the most common radiation shielding but it poses environmental hazards due to its toxicity. This research aims to study a non-lead radiation shielding and to evaluate its effectiveness of radiation protection. We studied radiation absorption properties from primary and secondary radiations from shielding composed of silicone rubber and BaSO4 and Bi2O3 in different proportions. The results showed that the shielding material at 70% BaSO4 and Bi2O3 has the ability to reduce radiation doses from 120 kVp X-rays and has absorption properties of 90.19, 94.87% in primary and 92.72, 97.48% in secondary radiation. In addition, the silicone rubber shielding materials mixed with BaSO4 and Bi2O3 are environment-friendly, flexible and have great shielding performance in reducing diagnostic X-ray exposure.
期刊介绍：
Materials Research Innovations covers all areas of materials research with a particular interest in synthesis, processing, and properties from the nanoscale to the microscale to the bulk. Coverage includes all classes of material – ceramics, metals, and polymers; semiconductors and other functional materials; organic and inorganic materials – alone or in combination as composites. Innovation in composition and processing to impart special properties to bulk materials and coatings, and for innovative applications in technology, represents a strong focus. The journal attempts to balance enduring themes of science and engineering with the innovation provided by such areas of research activity.
