DEVELOPMENT OF A MODEL FOR THE SPREAD OF RADIOACTIVE FALLOUTS

Abstract

Problem statement. The use of information technology and software leads to acceleration of concretely set tasks, increases the accuracy of calculations and minimizes the number of errors that can occur during calculations. The analysis of specialized software in the field of civil safety has shown the lack of software that would give the ability to estimate the area to which radioactive fallouts would spread in the case of a nuclear explosion or accident at a nuclear power plant. The purpose of the article is to develop a model that would accelerate the process of evaluating radiation contamination for territories with automatic mapping of nuclear cell areas, fire zones and the territory of radioactive cloud spread. The article describes a model for the spread of radioactive fallouts from nuclear explosions and accidents at nuclear power plants, which can accelerate the assessment of the radiation situation in any territory. Conclusions. With the help of this model, it is possible to forecast in a few minutes the spread of the radioactive cloud both in case of an accident at a nuclear power plant and in case of a ground or air nuclear explosion. The program allows you to make such forecasts anywhere in the world, because it is based on Google Maps. When using the program, the estimation of radioactive cloud propagation for four objects with different geographical location, different parameters of the explosion and wind parameters is about 15 minutes. The model is characterized by a convenient and clear interface that allows you to quickly assess the radiation situation without knowledge of the methodology itself.
