WebDeterministic (Non-Stochastic) Effects General Early (acute) effects are non-stochastic because they are pimarily brought about by cell death. Late (delayed effects) can be deterministic or stochastic. Deterministic late effects involve the death of slowly dividing 24 yg cells, e.g. those in the liver.
