3D plots of the theoretical inactivation ratios as a function of replication terms (0 ≤ Γ2 ≤ 2.0 × 10−4) for various dose rates. The red, green, and blue meshes correspond to dose rates PL, PM, and PH, respectively. The boundaries defining the effectiveness of dose rates are indicated by the curves XL1 (broken grey line), XL2 (solid line), and XL3 (dotted broken grey line).
