Minimization of the harmful effect from emergency situations with the pollution of chemical and radioactive substances into the atmosphere

Abstract

A comprehensive system for minimizing the harmful effect from natural and man-made emergency situations for the atmosphere has been developed. This system is based on the fact that the management decision support subsystem has a complex of mathematical tools for forecasting changes in the state of the pollution zone and implementing the process of influencing it and the decision implementation subsystem has effective methods of precipitation from the atmosphere of dangerous gaseous and dispersed substances by artificial rainscavenging. The pollution zone is monitored with the establishment of its dimensions, geographical coordinates, the height of the lower and upper limits, the chemical composition and the quantitative composition of pollutants, the dispersion of the polluting aerosol and meteorological parameters in the pollution zone. Space satellites, manned and unmanned aerial vehicles, ground mobile and stationary vehicles can be used as means of monitoring. The prepared monitoring results are sent to the management decision-making support system, where, based on the received data, using a developed set of calculation tools, precipitation intensity is predicted, which determines the rate of pollution removal from the lower atmosphere. The head of the pollution elimination process decides on the methods of impact and delivery of droplet formation activators to the impact zone. There is a possibility of integrating new and promising both chemical and physical methods of artificial influence on atmospheric processes into the developed method of minimizing the harmful effect from an emergency situation for atmospheric air.
