Survival curves of SQ20B cells irradiated with (open symbols) or without (closed symbols) a 48-h pre-exposure to 10 μ M IUdR, for the energies: (A) around iodine K-edge: 32.8 keV (triangle) and 33.5 keV (reversed triangle); (B) 50 keV (square); (c) 70 keV (circle). Each survival curve fit is derived from the dose and surviving fraction data (triplicate experiments).
