Assessment of the radioecological situation on the territory of the Yalta city district
The paper presents the results of the assessment of the radioecological situation on the territory of the Yalta city district in 2021-2022. In particular, on the territory of the city of Yalta, beyond its borders and in the Yalta mountain Forest Reserve. Measurements of the equivalent dose rate of gamma radiation in the surface layer of air were carried out in open areas and in residential premises, in three areas with different building densities and heights above sea level. A comparative analysis of the equivalent dose rate in different territories was also carried out, and the main contributions from various sources were evaluated. The average annual dose of the population was calculated, taking into account the ratio of the average time spent by a person indoors and outdoors. In addition, samples of the topsoil were taken and thespecific activity of the main radionuclides was measured. All measurements and sampling are carried out in accordance with GOST and methodological guidelines. To control and ensure human safety from the negative effects of radiation, norms and rules for ensuring radiation safety have been developed, among the main ones are NRB- 99/2009 and OSPROB-99/2010. Based on the data obtained, it can be concluded that the results of the annual dose slightly exceed the limits of radiation safety standards, while not posing a danger to the human body. The specific activity of radionuclides, according to the analysis of literary sources, does not exceed the global average.
