| Summary: | The precarious condition of several radioactive sources, and the aggravating situation with regard to how waste is accumulating without adequate storage and maintenance capacity on and along the Kola Peninsula have lately become recognised world-wide. Several major problems are related to the military sources, albeit those of a civil origin definitely also need consideration. The Kola-Barents region of the Russian Arctic exceeds, for example, all other regions and countries in the world regarding the concentration and number of nuclear reactors. One important environmental research issues for the Kola Peninsula as well as for northern Europe appears thus to be assessment of possible consequences after hypothetical accidents at such radioactive sources. Analyses of that kind are the main theme for the present project: ‘Radioactive sources on the Kola Peninsula: a radiological sensitivity analysis of potential cases of airborne accidental release’ of the ÖCB research programme ‘Risk and Nuclear Waste: nuclear problems, risk perceptions of, and societal responses to nuclear waste in the Barents region’. It is a progress report for the first year of the project, it has been focused on “modelling of episodes of atmospheric transport and deposition from hypothetical nuclear accidents on the Kola Peninsula. The report includes the results of modelling of atmospheric transport and deposition from potential accidents at the nuclear sites at the Kola Peninsula for meso- and regional scales. Several scenarios of airborne accidental releases are considered. Additionally, for this period an overview of population distribution and preliminary results of radiological effects to the population of the Barents / Scandinavian region. Den bekymmersamma situationen med avseende på hur radioaktivt avfall ackumuleras på Kolahalvön utan godtagbar kapacitet för underhåll och förvar har på senare tid uppmärksammats världen över. Flera av de stora problemen är förknippade med radioaktiva källor inom den militära sektorn, men de med ...
