| 内容記述 | Although electron paramagnetic resonance (EPR) detects stable organic radicals, it cannot verify the location of the radicals in a sample. In addition, most stable organic radicals appear around the g = 2.002 region of the spectrum. The 9 GHz EPR imaging can nondestructively verify the stable radicals in a sample. We investigated the stable radicals of crystalline sucrose radicals produced by C ion and X-ray irradiation at the same dose. The radicals were measured using electron paramagnetic resonance (EPR, a JEOL RE-3X) and 9 GHz EPR imaging (a Bruker E500 ELESYS system). Both irradiations of sucrose produce stable free radicals. EPR of sucrose radicals showed a linear increase of the signal intensity as well as accumulation of the dose. EPR imaging suggests that the radical distribution can vary with changes in LET and absorbed dose. The EPR and 2D EPR imaging results suggested that radical species were mostly located inside the sucrose crystal. Fewer radicals were found at surface region of the sucrose crystal. | |||||
