Dynamics of the content of technogenic radionuclides in the objects of veterinary supervision of the North-western region

Abstract

The operation of nuclear power plants inevitably leads to a deterioration of the environmental situation and, in particular, pollution of the environment with man-made radionu clides. In the context of environmental degradation, providing the population with high-quality and safe food is an important task. The veterinary service continuously monitors the content of biologically significant radionuclides Sr90 and Cs137 through scheduled periodic radiological monitoring of water, feed and livestock products at preestablished control points. The dynamics of the specific activity of strontium and caesium isotopes in milk and meat of cattle on the territory of the enterprises of the NorthWestern region during the period from 2008 to 2016 was studied. The results of research allow us to state that animal husbandry is carried out in the territory of the North-Western region in favorable radio-ecological conditions. It was established that the manufactured products coincides with the requirements of sanitary standards. The fluctuations in the activity of Sr90 and Cs137 in milk and meat, detected during the observation period, can be explained by the presence at the ratio diet of animals of forage, originated from other districts.
