Since the quadratic terms is zero, it is possible to obtain the net survival by just multiplying the fractions due to the bare gamma radiation with those due to the GNP ionizations, $S = S_\gamma \times S_\text{GNP}$ (additive approximation), whose LQ parameters in presence of GNPs are expressed as  \begin{align}  \alpha = &=  \alpha_\gamma + \bar{N}^0_\text{ion} \bar{N}_\text{GNP} \\  \beta_\text{GNP} = &=  \beta_\gamma \end{align}
