Abstract
This paper presents the results of radioecological research of the Karakol River basin in Issyk-Kul region of Kyrgystan. The Karakol River has a snow-glacier feed, the chemical concentration of the water is slightly mineralized and it is of calcium-hydrocarbonate-sulfate type. The concentration of radionuclide was determined in soil, water, river bottom sediments and the city of Karakol. The values of concentrations are varied within the natural regional background, but a significant increase of the specific activity of radionuclides was observed in the estuary zone of the river. The map of the level of the exposure dose of the territory of the city of Karakol was compiled with the help of the computer program "Surfer-12".
Highlights
The Karakol River originates from the Karakol Glacier from the northern slope of Teskey Ala-Too at an altitude of 5200 meters and runs into the Issyk-Kul Lake
The Karakol River refers to the rivers of snow and glacier feeding, the mode of its flow is closely connected with the air temperature regime, a secondary role in the feeding of the river acts on atmospheric precipitation and groundwater, and the last feeding refers to its up and down stream
Karakol City is located in the lower reaches of the Karakol River
Summary
The Karakol River originates from the Karakol Glacier from the northern slope of Teskey Ala-Too at an altitude of 5200 meters and runs into the Issyk-Kul Lake. The Karakol River refers to the rivers of snow and glacier feeding, the mode of its flow is closely connected with the air temperature regime, a secondary role in the feeding of the river acts on atmospheric precipitation and groundwater, and the last feeding refers to its up and down stream. The city is the administrative and cultural center of the Issyk-Kul region, the population was 73,000 people in 2016. The sustainable development program of region is associated with the assessment of the radiation impact on the population. The lack of public data in this area generates radiophobia among the population, which in turn makes it difficult to create a positive image of the Kyrgyz Republic, in which a significant part of economic development is related to tourism
