Abstract

This paper describes the passive remote method and its instrumental realization based on microwave radiometry for express diagnostics of radioactive elements in the atmosphere. The formation of ionized atoms and molecule in the atmosphere as result of radioactive emissions and the photochemical processes resulting in background radiation power are discussed. Analysis of the microwave radiation due to ionization and dissociation of atmospheric components interacting with radioactive elements is carried out. The photochemical processes resulting in background microwave radiation power are considered. Electron density formed in the emission plume from an atomic power station is estimated for β-active nuclides ⁴¹Ar, ¹³³Xe, ⁸⁵Kr, ¹³¹I, because they are main part of emissions from the atomic power stations and nuclei reprocessing plants. The influence of atmospheric conditions on such processes is estimated for different stratification of atmospheric parameters. As an example the results of natural experiment of detecting the atomic hydrogen radiation in the plume of emissions of nuclear cycle processing plants are presented.
