Abstract

Abstract: The capability of N-isopropylacrylamide (NIPAM) polymer gel to record the dose resulting from boron neutron capture reaction in BNCT was determined. In this regard, three compositions of the gel with different concentrations of 10 B were prepared and exposed to gamma radiation and thermal neutrons. Unlike irradiation with gamma rays, the boron-loaded gels irradiated by neutron exhibited sensitivity enhancement compared with the gels without 10 B. It was also found that the neutron sensitivity of the gel increased by the increase of concentration of 10 B. It can be concluded that NIPAM gel might be suitable for the measurement of the absorbed dose enhancement due to 10 B and thermal neutron reaction in BNCT. Highlights: Three compositions of NIPAM gel with different concentration of 10 B have been exposed by gamma and thermal neutron. The vials containing NIPAM gel have been irradiated by an automatic system capable of providing for dose uniformity. Suitability of NIPAM polymer gel in measuring radiation doses in BNCT has been investigated.
