Abstract

<p>The potential use of a sucrose dosimeter to evaluate linear energy transfer (LET) and absorbed dose measurement for heavy ion and X ray radiation was investigated with electron paramagnetic resonance (EPR) spectroscopy. The observed stable free radicals produced by irradiation with heavy-ions (He, C, Si, Ne ions) and X ray irradiation were similar and exhibit spectra of approximately 7 mT wide with several hyperfine structures. The radical yield produced by ion beam irradiation increased linearly as the absorbed dose increased and decreased logarithmically as the LET increased. In addition, the two-dimensional (2D) EPR imaging with a spatial resolution of ca. 0.37 mm was performed. The high radical intensities in relation to the C ion energy deposition are clearly observed at Bragg peak region.</p>
