The radiological consequences of operational atmospheric discharges from nuclear power plants are analyzed by using coupled long-range atmospheric dispersion models with time-dependent dose and risk assessment models. The coupled model is applied to atmospheric discharges from twelve assumed nuclear power plants located at three different sites in Turkey. Individual as well as collective doses and risks are analyzed. The effects of multi-location food supply and interregional movements of people in the computational domain are also investigated while computing individual effective dose and risk values. The values computed are found to be negligible compared with values from natural background and exposures from nuclear weapon testing.
