γH2AX foci in fibroblasts after a single helical chest computed tomography scan (a). Kinetics of γH2AX foci at the indicated times after exposure (0 = non-irradiated). Each data represents the mean ± standard error of the mean of three independent experiments. The asterisks shown at the non-irradiated conditions and at 10 min and 1 h post-irradiation times correspond to a statistically significant difference with the radioresistant control 200CLB data (p < 0.050). The asterisks shown at 24 h post-irradiation correspond to a statistically significant difference with the non-irradiated conditions for the same cell lines (p < 0.050). b Mean number of cells with more than 2 foci after a single helical chest CT scan. Data is shown as mean ± standard error of the mean of three independent experiments
