Response overshoot: a challenge for the application of polymer gel dosimeters

  • Seyed Mohammad Mahdi AbtahiEmail author


In this research response overshoots of the half irradiated PAGAT polymer gel dosimeter at variations post irradiation times were traced out. Results showed that 5 h after irradiation the measured dose by polymer gel dosimeter in boundary region are compatible with delivered dose. However, more elapsed time post irradiation caused misevaluation of dose. It was observed that response overshoot caused a maximum error of 28% in dose evaluation. It was concluded that more care is necessary when a high gradient dose distribution is evaluated by means of a polymer gel dosimeter.
