Correlation of γ-H2AX mean fluorescence intensity (MFI) and foci number with accumulated dose and performance to discriminate dose, (a) Correlation of the γ-H2AX MFI with the accumulated dose (p<0.001, r=0.71). (b) Correlation of the γ-H2AX MFI with the accumulated dose (p<0.001, r=0.55). (c) Receiver operating characteristic (ROC) curve analysis to discriminate radiation dose < 2 Gy from radiation dose ≥ 2 Gy based on γ-H2AX MFI. (d) Receiver operating characteristic (ROC) curve analysis to discriminate radiation dose < 2 Gy from radiation dose ≥ 2 Gy based on γ-H2AX foci number.
