Effect of temperature, irradiation dose, and dose rate on the retention of some radioisotopes in poly(methyl methacrylate)/phosphate/composites

► Preparation and characterization of methyl methacrylate/phosphate/composites using gamma radiation. ► Quantitative retention of radioisotopes (152Eu, 137Cs, 85Sr) in the prepared composites. ► High doses and dose rates lead to high retention ratios of radioisotopes. ► Degradation of retention ratios at high temperatures. ► Compensation of temperature effect through high doses and dose rates.
