Comparison between the three model predictions. (a) RBEα (top) and Rβ (bottom) as function of LET for (α/β)x = 2 Gy (left) and 10 Gy (right). (b) RBE as a function of LET for (α/β)x = 2 Gy (left panel) and 10 Gy (right panel) at 2 Gy reference photon dose. (c) RBE as a function of 4He ion beam physical dose for (α/β)x = 2 Gy (top) and 10 Gy (bottom) at 4 keV·μm−1 and 15 keV·μm−1 as shown in the left and right column, respectively
