\label{concentration}  Ratio of MDA-MB-231 breast cancer cells survival at 0 and 4 Gy with increasing concentration of gold relative to control. Experimental data for 160 kVp are shown as bullets. The LEM-AM formulation predicts the effects of gold concentration for 160 kVp (black), 6 MV (red), and 15 MV (blue) up to the nominal concentration used for the experiments (12 uM), $\mu$M),  after which the curves saturate.
