The evaluation of the long-term consequences of a nuclear accident in the code NACOS.
International Workshop on Real-time Computing of the Environmental Consequences of an Accident Release from a Nuclear Installation. Aronsborg (SWE), 1996/10/07.
To evaluate the long-term consequences of a nuclear accident and to simulate the effects of countermeasures on the doses received by the population a terrestrial food chain model was applied in the code NACOS.
The linear compartmental model of the migration processes of radionuclides has been solved analytically applying step-like functions of the parameters.
The data base built into the code makes possible the simulation of seasonal changes and the effects of the countermeasures whenever introduced.
The estimation of the ingested dose for different integration periods following the intake is based on an age-dependent dosimetric model.
The effect of the seasonality and of the countermeasures on the expected activity concentration in foodstuff and on the ingested doses following a unit deposition of 131I and 137Cs is demonstrated.
