↵* Cells from different platings.
↵† Irradiation for 48 h, corresponding to corrected absorbed dose of 13.5 Gy.
↵‡ Cells were taken for DNA quantification 3 d after ending 131I radiation. No statistically significant differences were obtained between irradiated and control cultures. Results are presented as mean ± SEM (n = 3).
