γH2AX foci in fibroblasts after a single helical chest CT scan, with or without topogram. a Kinetics of γH2AX foci in fibroblasts after a single helical chest CT scan, with or without topogram at the indicated times after exposure (t0 = non-irradiated). The irradiation protocol corresponds either to a single dose of 14.4 mGy or to a dose of 1.1 mGy followed, after 1 min, by 14.4 mGy. Each data represents the mean ± standard error of the mean of three independent experiments. Asterisks at 10 min post-irradiation correspond to a statistically significant difference between conditions with or without topogram for the same cell lines (p < 0.05)0. 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 two foci after a single helical chest CT scan with or without topogram. Data is shown as mean ± standard error of the mean of three independent experiments
