Abstract
Many of the physical and chemical properties of polymer materials can be altered by high energy radiation. In the present work the exposure to radiation of low density polyethylene(LDPE) included antioxidants was carried out at various doses up to 600kGy at a dose rate of 5kGy/hr in the presence of air at room temperature. The study of the irradiation effects on the material properties has been make by different methods in an integrated way. The experimental data indicate that the decomposition onset temperature(DOT), the crystallinity and the thermoluminescence(TL) with radiation dose. DOT, crystallinity and TL analysis from irradiated PE samples provides useful data for the characterization of radiation-induced oxidation effects on these samples.
