本文介绍了哈萨克斯坦与吉尔吉斯斯坦边境附近的Shu河、Shor-Koo河、阿克苏河、Karabalta河、Toktas河和Tasotkel水库的放射性测量和水体（土壤、底质沉积物、水）中放射性核素和元素组成的测定结果。土壤和底质样品中天然放射性核素238 U和232 Th系列、As、Co、Cs、Cu、Hf、Mo、Pb、Sb、Sc、Zn、Zr和稀土元素含量增加。水样中的B、As、Mo、Ba、U等有毒元素含量明显增加。吉尔吉斯斯坦境内的辐射危险场址对跨界河流受到天然放射性核素和有毒元素污染的负面影响已被揭露。
The paper presents the results of radiation surveying and determination of radionuclide and elemental composition in water objects (soil, bottom sediments, water) of the transboundary rivers Shu, Shor-Koo, Aksu, Karabalta, Toktas as well as of Tasotkel water-storage in Kazakhstan in vicinity of the border with Kyrgyzstan. Increased contents of natural radionuclides of238U and232Th series, As, Co, Cs, Cu, Hf, Mo, Pb, Sb, Sc, Zn, Zr and rare earth elements were observed in soil and bottom sediment samples. Increased contents of the following toxic elements were revealed in water samples: B, As, Mo, Ba, U. Negative influence of radiation-hazardous sites in Kyrgyzstan on the contamination of the transboundary rivers with natural radionuclides and toxic elements was revealed.
