Preparation, characterization and comparative ionizing electromagnetic radiation performances. Part 1. Metal oxide reinforced polymeric composites

Isophthalic polyester resin was reinforced by using different metal oxides (lead(II)oxide, tungsten(VI)oxide and ferric oxide) and different reinforcement ratios (10-50%). Ionizing electromagnetic radiation shielding performance of the composites were determined by gamma spectrometric techniques for three different ionizing electromagnetic radiation (IEMR) energy regions (60-392, 662-898, 1173-1836 keV). Density evaluation, FTIR analysis, SEM studies were carried out. The IEMR attenuation performances of the composites were determined with gamma spectroscopy and found to be satisfying. These composites give better performance with respect to reference lead, especially in the case of the applications that weight of IEMR shield is important. (author)
