Some Metal Oxide-Natural Rubber Composites for Gamma- and Low-Energy X-Ray Radiation Shielding

This work studied protective material consisting of several metal oxide composites (Pb3O4, WO3, SnO2, and Bi2O3)-natural rubber (NR) for X-ray gamma-ray shielding. The were prepared through open milling vulcanization processes further characterized by scanning electron microscope (SEM), diffraction (XRD), rheometry analysis, density gauge. attenuation coefficient the sample was investigated using generators with voltages ranging from 50 to 140 kV energies 356 1250 keV, respectively. experimental results show that linear NR filled oxides significantly improved compared pure NR. For 661 HVL decreased 9.0 cm between 4.4 - 6.2 after it oxides. Bi2O3-NR is best suitable attenuation, followed Pb3O4-NR, WO3-NR, SnO2-NR. Meanwhile, x-rays, 2.0 0.17 -0.31 proposed oxide-NR can be appropriate as a flexible manufacturing wearable radiation shielding products such gloves, aprons, underwear, other materials.
