| 抄録: | We investigated the sucrose radical-production cross section induced by heavy-ion irradiation. L-alanine was also used in order to compare radical yield and cross section. The stable free radicals after irradiation were analyzed by EPR (electron paramagnetic resonance). The radical yield obtained by the irradiated samples had a logarithmic correlation with the LET (linear energy transfer). Quantitative EPR analyses showed that radical productions for sucrose and L-alanine vary both by different particle irradiation and the LET under the same absorbed dose. Furthermore, the cross sections of radical productions for samples were calculated. Both cross sections for C ions irradiation under LET 30 [keV/μm] at 50 Gy dose were ~3.0 x 10<sup>-9</sup> [μm<sup>2</sup>], taking account of the molecular areas of the samples. The values of the cross sections imply that multiple ionizing particles involve producing stable radicals. |
