Stochastic

With respect to Radiation Protection, stochastic effects (also referred to as Probabilistic) represent radiation harm for which there is no threshold (see Linear Dose Response). Even the smallest quantity of Ionising Radiation exposure can be said to have a finite probability of causing an effect, and this effect being either cancer in the individual or genetic damage. Dose Limits are set to ensure that these effects are minimised to broadly acceptable levels. Also see Deterministic Effect.
