Abstract: Polymer gel has been used as a dosimeter to determine spatial dose distributions by radiotherapy equipment. This study studies the absorption peak in the UV-visible (UV-vis) spectrophotometer as the relative intensity of polymerization. Theoretically, high intensity of polymerization results in high absorbance. The size of gold nanoparticles (GNPs) and dose of irradiation are expected to affect polymerization. Normoxic polymer gel samples using 2-Hydroxyethyl methacrylate (HEMA) as the monomer were prepared with different sizes of GNPs in order to study the effect of GNPs with ascorbic acid acting as the oxygen scavenger. Linear accelerator (LINAC) was the source of high irradiation x-ray energy as it is one of the most widely used radiotherapy equipment. Diagnostic x-ray unit acted as the low energy sources. One crucial factor in fabricating the sample is the environment temperature. Radiation induced polymer gel is environmentally sensitive where low temperature environment (
