Abstract

The expression of survival factors for radiation damaged cells is empirical and based on probabilistic assumptions. We obtain it either from the maximum entropy principle for the classical Boltzmann-Gibbs entropy and/or from the Tsallis entropy. Empiric models are found to be particular cases of the obtained expression. The survival factor exhibits a phase transition behaviour. This formulation supports different tissues grouped as universality classes.
