Abstract
This study presents an experimental analysis of the effect of dose parameter during gamma irradiation of commercial high-density polyethylene (HDPE) samples. The effect of different doses of γ-irradiation on the physical and mechanical properties of HDPE with different thickness (1 mm and 2 mm) was studied. The effect of -irradiation on HDPE led to remarkable changes in the physical and mechanical properties of the samples due to chain scission, oxygen effects and crosslinking activities. The experimental results show the mechanical properties reduce as radiation dose increase, also, it was found that HDPE with thickness (1 mm) is more susceptible than HDPE with thickness (2 mm) according to the influence of radiation.
