CAESIUM-137 AND STRONTIUM-90 CONCENTRATION IN PINE FOREST MEAT IN DIFFERENT ECOLOGICAL ZONES OF THE REPUBLIC OF SAKHA (YAKUTIA)

The article discussesthe current problem of food quality control, the content ofstrontium-90 and cesium - 137 in the body of wild game birds-wild game inhabiting the territory of the Republic of Sakha (Yakutia). The object for research were carcasses of wild game 3 species: black grouse; partridge; grouse. Radiation safety of wild game as a food product was determined by its compliance with permissible levels of specific activity of radionuclides, in particular 137Cs and 90Sr. These indicators are regulated by TR CU 021/2011 “on food safety”. According to the long-term (2013-2017) results of our studies 137Cs and 90Sr in carcasses of wild game, Northern, Central, Vilyuisk and southern ecological zones of the Republic of Sakha (Yakutia) was not found to exceed the permissible concentration. As a result of our research, the following results were obtained: the content of 137Cs and 90Sr in grouse carcasses: southern - 70.54±0.71 and 26.43±2.54; Central-64.81±0.18 and 20.89±1.95; Vilyuiskaya - 73.12±0.01 and 28.48±1.18.

In the study of grouse is established: the content of radionuclides in the southern zone - 71,24±1,95; Central was 60.05±0.01 and of 21.11±1,95; Vilyui - 71,11±0.55 and of 11.47±0,32. According to the results of our studies, the data of exceeding the maximum concentration of 137Cs and 90Sr in the carcasses of wild game in all ecological zones of Yakutia were not established.
