Abstract
The aims of this study are to increase the melting point of a normoxic Methacrylic acid-based polymer gel as well as investigation of its responses to thermal neutron and gamma irradiation. New polymer gel was named MAGIC-A (MAGIC and agarose). The R 2-dose sensitivity of MAGIC-A polymer gel for gamma irradiation was 0.381 ± 0.010 Gy−1 s−1 at 24 h post irradiation time which decreased to 0.180 ± 0.004 Gy−1 s−1 for thermal neutron irradiation. Results of this research confirmed the applicability of the MAGIC-A polymer gels for dosimetry of thermal neutrons as well as gamma irradiation.
