Comparison of the calculated C/N ratios with the DSB/SSB ratios obtained from the detailed DNA damage simulation of Kundrát et al.13 (a) and the relationship between normalized Quality of Beam (QoB) (using 2.1 nm as the optimal value of the maximum cluster radius, ε) and simulated DSB yields reported by different investigators15,19,35,36 (b).
