Radioecological situation on the territory of the Volga Region Department of Hydrometeorology and Environmental Monitoring in 2016

Abstract

The environment quality is an extremely relevant question, including taking into account radio-ecological situation. The development of local agriculture should take into account various radiation parameters that determine the current radiation situation. In particular, it is necessary to do regular radioecological monitoring of environmental pollution of the Samara Region and adjacent territories on the main types of radiometric observations. The paper focuses on the reliable and rapid detection of radioactive contamination, assessment of the radiation situation with the help of radio-ecological control of natural environment components. In the paper on the basis of the Volga Region Department of Hydrometeorology and Environmental Monitoring data the authors assess the radiation situation in the settlements of Samara, Saratov, Orenburg, Penza and Ulyanovsk Regions. The paper contains values of aerosols -activity concentration in the surface layer of the atmosphere as well as the data of the average annual values in Samara and adjacent regions. According to the data of radioecological monitoring the level of total -activity of radioactive fallout from the atmosphere is shown. The maximum values of the total -activity concentration of the atmospheric surface layer aerosols were recorded in summer, which is due to the secondary wind dust rise from the contaminated areas. It was shown that the average annual value of the total -activity of aerosols according to the results of studies is within the normal limits. The paper also contains conclusions about the degree of danger of the atmosphere surface layer contamination by technogenic radionuclides.
