Abstract

Were contaminated as a result of the Chernobyl accident in the Leningrad region, the territories of the Kingiseppsky, Volosovsky, Luzhsky, Gatchinsky and Lomonosovsky districts. The area contaminated with 137Cs over 1 Ci/km2 was 5711 km2. A number of settlements in the Kingiseppsky and Volosovsky districts were classified as zones with preferential socio-economic status. In order to normalize the environmental situation, partial decontamination of the Chernobyl contamination zone was carried out, as a result of which, since 2015, the list of settlements with a critical level of radionuclide contamination has been significantly reduced. However, significant contamination is observed in a number of settlements in the Kotelskoye rural settlement of the Kingiseppsky district, which became the basis for conducting a radiation and hygienic survey of veterinary supervision facilities in the Loban G.M. Peasant Farm and Kotelskoye Joint-Stock Company. In each of the agricultural enterprises, average weighted samples of soil and plant products were taken. A high content of radionuclides in the arable soil layer was established: 137Cs – 316+-21 Bq/kg and 90Sr – 273+-17 Bq/kg. At the same time, the content of radionuclides in plant and water products did not exceed the control values. Thus, despite the increased level of soil contamination as a result of the Chernobyl accident almost 40 years ago in the territory of the noted areas, the radiation and hygienic examination did not reveal an excess of the intervention level for the content of 137Cs and 90Sr in plant products, which allows them to be used for their intended purpose without restrictions.

Key words
Chernobyl accident, contaminated areas, 137Cs, 90Sr, regulation of radioecological conditions, plant products, radiobiology, environmental health.
