Modeling and Prediction of Radiation Emergency Impacts on the Nuclear Facility Surroundings

The thesis is focused on the modeling and prediction of Radiation Emergency Impacts on the Nuclear Facility Surroundings with a usage of a software program ESTE EU, designed to detect and to evaluate the prognosis of the leakage of radioactive substances into the surrounding of the Nuclear Facility in case of an exceptional radiation situation. Furthermore, in the theoretical part, basic radiation protection units, main international radiation protection and safety organizations, options for monitoring of the radiation situation, from a rightful legislation derived terms regarding the exceptional radiation situation, a crisis management during an accident involving radiation, safety measures in a disaster planning zone and a description of the software program ESTE EU, are discussed. In the practical part it is dealt with the modeling and prediction created with an assistance of the ESTE EU software, the evaluation of the prognosis of the exceptional radiation situation, a suggestion of an urgent population safety measures, which are in accordance with the legislation and meteorological conditions - especially the velocity of the wind and the sum of precipitation on radiation exposure of representative person. The main goal of the thesis was to learn how to use the software program ESTE EU, create two modelation of exceptional radiation situations, compare those situations and propose urgent safety measures. The thesis provides information and summary of this area issues to subjects with an access to the software program and/or to those, who will use software's outputs to decide whether to accept some measures or procedures
