Abstract
The scope of this research is to determine the degradation of mechanical properties of cable insulating PVC after irradiation in air at a Cobalt-60 ({gamma}-ray) facility. Amongst the mechanical properties elongation at break and tensile strength were chosen as they are the most sensible to radiation. The samples were exposed to combined radiation-thermal environments with constant airflow in order to obtain accelerated aging data a doses up to 50-300 kGy, with dose rates ranging between 1.3 and 5.6 kGy/h at temperatures from 60 degrees C to 100 degrees C. At lower dose rates the degradation of mechanical properties increased after the same total dose: elongation at break decreases sharply while tensile strength decreases to a less extent, showing dose rate effects. A strong synergy between irradiation and thermal processes was also observed. (author).
