Regional radiation risk and vulnerability assessment by integration of mathematical modelling and GIS analysis

摘要

The Kola Peninsula, Russian Arctic exceeds all other regions in the world in the number of nuclear reactors. The study was aimed at estimating possible radiation risks to the population in the Nordic countries in case of a severe accident in the Kola Peninsula. Two approaches were tested: (1) probabilistic analysis of modelled possible pathways of radionuclide transport and precipitation and (2) deterministic approach (Case studies) for most possible or worst-case scenarios of modelled transport and deposition of radionuclides.
