Abstract :
Low density polyethylene was irradiated with gamma ray up to 1000 kGy at a dose rate of 5 kGy/hr in the presence of air at room temperature. Each irradiated samples were carried out thermo-luminescence detection, dielectric and dynamic mechanical analyses as a function of temperature. The results of dynamic mechanical analysis are good related to those of dielectric analysis
