Computer System For Estimation And AnalysisOf Radioactive Contamination Of Surface Water

The given work presents description and practical representation of the specialized system of computer models for estimation of consequences of radioactive accidents and other releases of radioactive substances to an environment (water systems). A number of models are integrated in specialized GIS (geographical informational system) if that is required by problems being solved. The variety of models (model for river, for small simple lake, for complicated basins, etc.) on prediction of concentration in various types of water objects is stipulated by large zones of influence of nuclear reactors. The models are integrated in the number of confined chains that enable full calculation from an accident parameters to resulting pollution and health harm. On the base of calculated results appropriate actions are recommended. System is «open» so it can be expanded and improved by other models. A prototype of decision support system for emergency radioactive pollution based on the computer models complemented with regulative documents database is also presented. The system will support decision making on population protection in an emergency situation and «what if» process through radioactively dangerous object projecting. For creation of the computer bank of models and decision support system modern information technologies are used. Validation and verification of computer models are carried out now. Some of models were verificated on the Chernobyl accident contamination data. Consequences of nuclear submarine accident (1985) in the Chazhma Bay (near Vladivostok) are analyzed now and models are verificated with the aid of this data.
