Cell survival curves after 4 and 18 MeV electron irradiation. (A) Cell survival curves for cells irradiated using the standard assay and (B–D) using the alternative assay; (B) total counts, (C) center region, and (D) wall region. Error bars indicate the standard error of the means for three independent experiments.
