Mathematical modeling of total dose to a hypothetical resident in the environment of nuclear facility by contamination through the atmosphere

Abstract

This paper presents an algorithm for the calculation of internal and external doses, which is an integral part of the mathematical model of atmospheric dispersion. Results of modeling were compared with values from an IAEA publication for a given scenario of radionuclide emission to the atmospheric boundary layer. Due to small differences in the results, compared to the IAEA recommended model, model presented in the paper can be used as a basis for this type of analysis. In order to illustrate the application of this mathematical model (atmospheric dispersion + module for the calculation of radiation doses), using data of the hypothetical emission of radionuclides,, ventilation parameters, then 3D topography and meteorological data, field of total annual dose received by a hypothetical resident in the vicinity of the reactor, during its routine operation over one-year period is presented.
