Modeling the process of wet deposition of radioactive impurities in the atmosphere using the model DERMA
Keywords:
air pollution, wet deposition, forecasting, DERMA model, radioactive impuritiesAbstract
The paper studies the process of wet deposition of radioactive impurities, including their interaction with rain, snow, and fog. Mathematics models describing the deposition process are presented based on data from the meso-macroscale DERMA model. An analysis of the influence of meteorological conditions and particle size on their trajectory and deposition distance is carried out. Based on data from the Samarkand meteorological station for 2023, calculations of the deposition of particles of various sizes were performed using the developed methodology. The calculation results demonstrate the importance of taking into account meteorological factors and particle size for predicting air pollution and planning measures to reduce their impact of wet deposition of radioactive impurities in the atmosphere using the DERMA model.
