Abstract
Understanding the chemistry of radiation-induced polymerization in polymer gel dosimeters is of great importance in the evaluating of the capability, stability and efficacy of the polymer gel to measuring accurately the three-dimensional dose response.The aim of this work is to characterize the chemical and structural modifications induced by gamma irradiation in normoxic MAGIC polymer gel under different experimental conditions. These modifications have been investigated using FTIR, HPLC, SEM and UV–Visible techniques. Radical formation, chain growth and crosslinking termination processes were considered from FTIR, HPLC results while the polymerized particle sizes were derived from UV–visible and SEM results for different absorbed doses.
