Relationship between the fraction of residual Rad51 foci remaining at 24 h (relative to the maximum level of Rad51 foci at 4 h) after irradiation with 10 Gy and clonogenic survival at 2 Gy (SF2) in NSCLC cell lines. A linear fit through the data points indicates an inverse relation between the fraction of remaining Rad51 foci and SF2 (P=0.006; r=−0.994).
