Abstract

The article focuses on the study of the possibilities of a microwave radiometer for remote detection of increased radioactivity in the plume of gas-aerosol emissions from nuclear power plants caused by fast neutrons. This is a highly relevant issue due to the recent commissioning of new reactors using fast neutrons and the high number of accidents at nuclear facilities. The technical characteristics of the radiometric system are presented, and a quantitative analysis of radioactive emissions from nuclear power plants with fast neutrons is conducted. A slight decrease in the total amount of radioactive emissions is observed. The physical and chemical interactions between the released radionuclides and atmospheric components are also investigated. The maximum distances within line-of-sight at which gas-aerosol radioactive emissions can be detected in real-time mode in the frequency range of 1.4-1.8 GHz are determined.
