Abstract
This paper presents a method for measuring the effectiveness of radiomodification using a ferrous sulfate dosimeter, including evaluating the antioxidant activity of the radiomodifying agent. The effect of adding cerium oxide nanoparticles at the concentration of 100 μg/ml on the change in the absorbed dose recorded by the ferrous sulfate dosimeter when irradiated with inhibitory radiation with doses of 25, 50 and 75 Gy was investigated. The results showed low antioxidant activity of the examined nanoparticles and the effect of increasing the absorbed dose in proportion to the irradiation time.
