Procedure for Implementation of the Method of Artificial Deposition of Radioactive Substances from the Atmosphere

Abstract

Studies on the processes of emergency response at the facilities of the atomic-energy complex with the release of gaseous and dispersed radioactive substances into the atmosphere allowed us to develop a procedure for the practical implementation of this method. The emergency response method is aimed at precipitating hazardous radioactive substances from the atmosphere that enter the atmosphere during man-made accidents at nuclear power plants and other facilities for the storage and processing of radioactive substances. The developed procedure on the proposed algorithm of actions operates within the framework of a unified state system of civil protection. The presented procedure allows to solve three main tasks of liquidation of consequences of emergency situations - it is monitoring of the affected area, making effective management decisions and direct influence on the affected area from the emergency.The basis for making effective management decisions is to predict the dynamics of radiation contaminated zones, predict the intensity of precipitation with various methods of artificial precipitation and predict the effectiveness of precipitation effects on the dynamics of changes in contaminated areas. In order to expand the capabilities of existing methods for predicting pollution zones, their modification has been proposed taking into account the features of precipitation. The use of this procedure allows minimizing the scale of major emergency situations at the regional and state levels. Due to the use of artificial sedimentation methods, as provided for in the procedure, there is the possibility of precipitating dangerous radioactive substances from the atmosphere from a height of several kilometers, which cannot be implemented by other known methods. The developed algorithm of actions and the procedure for implementing the emergency response method by artificially initiating precipitation are the basis for the development of a procedure for practical emergency rescue units during emergency response at regional and state levels. Thus, there is reason to believe that the use of the proposed procedure will improve the efficiency of man-made emergency response operations with the release of hazardous radioactive substances to the atmosphere.
