Dispersion models play a significant role when incidents involving the release of radioactivity occur. Dispersion forecasts are an important aid for the timely assessment of risks to the public (i.e. prior to the actual release), for the isolation of the area affected and for decisions on the necessary protective measures.
The NEOC uses various dispersion models to assess the effects of both local and large-scale dangers. Here, it relies on the specialist expertise of external partners:
- The NEOC can rely on various models from the Swiss Federal Nuclear Safety Inspectorate (HSK) to calculate local dispersion at Swiss nuclear power plants;
- The NEOC relies on MeteoSwiss algorithms for large-scale dispersion calculations.
