Ecological Systems and Devices Annotation << Back Metrological aspects of pollution spreading calculation in case of radiation accident on the atomic power station A.D. Kosov , S.S Poliancev At the description of process of pollution spreading in environment Gauss models of dispersion and the models as much as possible approached to real conditions are used. Accuracy of calculations according to pollution spreading is connected with an estimation of uncertainty of model and does not depend directly on its degree of closeness to modelled process. Studying and the analysis of components of uncertainty of results of calculation of pollution spreading in environment is not only the important direction of improvement of modelling representations, but also means of formation of approaches to the decision of narrower practical problems. Key words: radiation accident; radioactive pollution; the atomic power station; model admixture dispersion; uncertainty meteorological condition. E-mail: sultan1160@mail.ru
