Surviving Fraction
Figures 1 through 5 show comparisons of measured and RMR or TLK predicted survival data as a function of dose and dose rate.  For CHO 10B2 cells (Figure 1b), survival data for a 16 Gy (8 Gy + 8 Gy) split-dose irradiation scheme are also available.  For each type of cell, a single RMR or TLK model parameter set does an adequate job at explaining the observed cell survival data.
