Normalized mean apoptotic events (N')fd induced by 150 kV X-rays under the different filtration conditions of F0, F1 and F2, with respect to different X-ray doses. For each filtration condition, three sets of experiments were performed and the normalized data were pooled together. Cases with P < 0.05 are asterisked and regarded as corresponding to statistically significant differences.
