In the present paper, a two-age-class group, logistic growth model for generic populations of nonhuman biota is described in order to assess non-stochastic effects of low linear energy-transfer radiation using three endpoints: repairable radiation damage, impairment of reproductive ability and, at higher radiation dose rates, mortality. This model represents mathematically the exchange between two life stages considering fecundity, growth and mortality. Radiation effects are modelled with a built-in self-recovery pool whereupon individuals can repair themselves.
