HISTORICAL EVALUATION, REVIEW AND ANALYSIS OF THE DEVELOPMENT OF URANIUM MINING IN THE REPUBLIC OF BULGARIA

Abstract

Meteorological elements affecting radioactive contamination of the environment, each indicator has a different weight in the formation of the radioactive background. The strongest influence on the spread of radioactive contamination have winds. Influenced also different rainfall and the permeability of the atmospheric layer to solar radiation reaching us. The other meteorological components have a negligible impact on the spread of radioactive rays, particles and isotopes and therefore in further research we will ignore them and will not recognize their influence on climate radioactive background. In the analysis of meteorological elements that influence the spread of radioactive particles and radioactive isotopes in Bulgaria are mainly analyzed winds and air currents that form in the airspace over Bulgaria. These are the main weather elements that most influence the climate of the radioactive background. Another element that influences is precipitation in its various manifestations - horizontal and vertical type and depending on the physical condition of the water. The other meteorological elements because of their vile influence of the radiation situation will exclude them from the factors shaping the natural indicators of the state of the atmosphere, water and pochvata.Analizat is made on the basis of detailed statistics on the direction and strength of the wind and air currents over the territory of Bulgaria in the last 30 years. In addition to daily data for the period after 2009 have used aggregated figures on the direction and strength of winds, and near the concerned areas and over throughout our country and in adjacent border areas. This data is used for a period of 20 years, which is enough to capture the trends of change of atmospheric masses and neighboring aquatic and terrestrial surfaces. I must point out that monitoring of air masses over the past 25 years gives us only the main trends and directions, but as we all know, these processes are too dynamic and not subject to cyclic steady repetition and prediction. So at the same time made extensive research and data processing should not disable the constant monitoring of our environment and its parametri.Kato main potential sources of radioactive contamination are discussed nuclear power in Europe. In analyzing the results of the forecast movements of air masses and spreading radioactive particles consequently observed that apart from the NPP "Kozloduy" and adjacent to Bulgaria Kozloduy "Black Water" at different intervals of time radioactive contamination may occur and result of an accident in other NPPs in Europe.
