Fig 1. Clonogenic survival fraction of A549, H1299 and BEAS-2B cells irradiated with 125I seeds and 60Co γ-rays.

Fig 1

A-C: the difference in the survival fraction of A549, H1299 and BEAS-2B cells between 125I seeds CLDR radiation and 60Co γ-ray HDR radiation. * indicates a significant difference (P<0.05) when comparing the two radiation treatments and control treatment, and # indicates a significant difference (P<0.05) when comparing 125I seeds CLDR radiation and 60Co γ-ray HDR radiation of the same doses. D, E: The difference in the survival fraction of the three cell lines receiving the same treatment. * indicates a significant difference (P<0.05). Bars, standard error (SE).
