The survival curve for proton was obtained and the inactivation cross-section was 0.863 µm2, which indicates that 150 protons are necessary for cell inactivation. DSB induction rates, R were measured using pulse field gel electrophoresis and FAR analysis. The R values for H, C, Si, and Ar ion were 0.0065, 0.137, 0.563, and 0.355DSB/Mbp/Fluence (particles/µm2) respectively.}, pages = {100--102}, title = {Braggピーク近傍の重粒子イオンを用いたイオン特異的なDNA損傷の誘発と修復}, volume = {2006}, year = {2007} }
