Sucrose radical-production cross-section regarding heavy-ion irradiation

Abstract

Abstract:We investigated the sucrose radical-production cross section induced by heavyion 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

Sucrose as double-signal high-dose dosimeter for ionizing radiation

“…A possibility to use sucrose as radiation sensitive material for high-dose EPR dosimetry was investigated by Generalova et al (1993), Flores et al (2000) and Yordanov et al (2002). Nakagawa and Nishio (2000), Nakagawa et al (2008) and Karakirova et al (2008) applied sucrose to high-LET dosimetry.…”
