Paper Abstract

The problem of remote detecting of a radioactivity in emissions from atomic power stations (APS) is devoted. The basic radionuclides contained in emissions of nuclear energy stations with various types of reactors have been analyzed. The total power spectrum of electrons is determined taking into account their multiplication. Physical and chemical reactions reducing to generation of atomic hydrogen are considered. For definition of the radiating volume in the emission from APS, the spatial distribution of atomic hydrogen concentration has been calculated with the use Pasquill- Gifford model. Power radiating by the emission plume from the APS with the BWR (Boiling Water Reactor) is estimated. It has been shown, that for estimation of radiation effect on the atmosphere, it is necessary to take into account many generations of electrons, because they have average energies exceeding considerably the ionization potentials for atoms and molecules of the atmospheric components. The area of the maximum concentration of atomic hydrogen in an emission plume can be determined by modelling the transport processes of admixture. The power radiated at frequency 1420 MHz by the volume 1 km from the APS emissions can amount to ~10 -13 W that allows one to detect the total level of activity confidently. The possible configuration of an emission plume has been calculated for various atmospheric stratification and underlying surfaces.
