Abstract

Data on the concentration of ¹³⁷Cs is obtained from soils, food plants, and muscle tissue of seven species of game animals (wild reindeer, elk, roe deer, musk deer, bighorn sheep, white hare, and brown bear) in the tundra and taiga zones of Yakutia. It has been shown that reindeer and musk deer are consumers of bushy lichens, are characterized by a relatively high content of ¹³⁷Cs (up to 51.6–75.1 Bq/kg), and can be a source of its intake into the organism of the next level consumer—the brown bear. The levels of ¹³⁷Cs in other herbivorous species are relatively low. Meat products of a number of species constitute an important component of the nutrition of the population of reindeer herding and hunting and hunting regions of the Far North. At present, the concentrations of the radionuclide in the tissues of the species studied do not exceed the established sanitary and hygienic standards.

雅库特地区全球 137Cs 污染及野生动物饲料和组织中的含量

摘要

¹³⁷ Cs的浓度数据是从苔原和沙漠中七种野生动物（野驯鹿、麋鹿、狍、麝、大角羊、白兔和棕熊）的土壤、食用植物和肌肉组织中获得的。雅库特的针叶林区。已经表明，驯鹿和麝是浓密地衣的消费者，其特征是¹³⁷ Cs 的含量相对较高（高达 51.6-75.1 Bq/kg），并且可以作为其摄入下一个生物体的来源。级别消费者——棕熊。等级¹³⁷其他食草物种中的 Cs 相对较低。许多物种的肉制品构成了远北驯鹿放牧和狩猎和狩猎地区人口营养的重要组成部分。目前，所研究物种的组织中放射性核素的浓度没有超过既定的卫生标准。
