Synthesis and characterization of silicone rubber composite silica as the x-ray shielding

Radiodiagnostics are diagnostics utilizing X-rays or radiochemical tracers. At the time of exposure using radiation, there may be radiation exposure that will affect the radiation workers. The purpose of this research is to develop materials that can be used as radiation shielding while maintaining radiodiagnostic examination results. This material is made by combining silicone rubber (SR) and silica composites materials through a simple process with a sample size (12 x 12 x 0.5 cm3). Samples were made in 2 variations using silicone rubber and silicone rubber-6% silica composite. Both samples were then tested using a mobile X-ray plane with tube voltage variations of 46 kV, 50 kV, 60 kV, 70kV, 81kV, 90kV, and 102kV, respectively. After being tested, the results of the X-ray transmission percentage for SR sheet at the minimum and maximum voltage are 60% and 75%, respectively. For SR-6% Silica sheet X-ray transmission percentage at the minimum and maximum stresses of 58% and 74%, respectively. This research results showed that the use of silica on SR has potential as a composite material that can provide increased absorption of X-ray radiation. (paper)
