Survival curves of SQ20B cells irradiated with (open symbols) or without (closed symbols) 10 mg ml−1 iodine incorporated as contrast agent in medium, for the energies: (A) around iodine K-edge: 32.8 keV (triangles) and 33.5 keV (reversed triangles); (B) 50 keV (squares); (C) 70 keV (circles). Each survival curve fit is derived from the dose and surviving fraction data (triplicate experiments).
