It was our intention, in this study, to assess the impact on the population in terms of received doses for different routes of exposure after a severe nuclear accident, and to determine the optimal planning distance parameter in the area of application of urgent measures of protection and rescue. The primary objective was to determine the model of exposure in terms of the received effective dose and thyroid dose as well as the received bone marrow dose which allows statistical observation of the calculation results and the determination of appropriate distribution. The primary analysis was performed by repeatedly launching the computing system RODOS with modified input data in consideration of wind speed and the atmospheric stability class. Model exposure is based on the statistical analysis of the data collected. This paper shows the results of repeated launching of the RODOS system and the statistical processing of the results. Described in detail it approaches the analysis, defining input data in form of PSA source terms, further to this, the calculation model based on available models of the dispersion of radioactive clouds in the RODOS system and the method and results of statistical processing of data collected in a form that allows easy evaluation of consequences in relation to the distance from the NPP Krško. The method of analysis was carried out at the premises of the State Office for Radiological and Nuclear Safety (SORNS) using the available computational resources of the SORNS.
