Polycarbonate Urethane (PCU) is a material of growing prominence for use as a biocompatible material for joint replacements. PCU has good wear properties, is easy to lubricate, and is very compatible with natural tissues. Extensive studies stil have not been performed to fully investigate the radiation effects on PCU components. Thermally stimulated luminescence (TSL) spectroscopy is a powerful tool to study radiation-induced defects in materials, while electron spin resonance (ESR) is a technique to directly detect free radicals in a material. To better investigate radiation effects on PCU materials, we have subjected PCU to X- and UV-irradiation and analyzed the thermally-stimulated luminescence (TSL) and radiation-induced free radicals. The materials used for the study were Bionet hip linear obtained from Active Implants Corporation. The resulting TSL and ESR data were analyzed to obtain new insights into the molecular properrties of Polycarbonate urethane.
