本文报道了哈萨克斯坦境内查干、乌拉尔、伊勒克、托博尔、阿亚特、额尔齐斯河、埃梅尔河、伊利尔河、特克斯河、舒河、卡拉巴尔塔河、塔拉斯河和锡尔达里亚河交界地区的水、底泥和土壤样品的放射性核素和元素组成的研究。所采用的分析方法包括：仪器伽马射线能谱法、放射化学分析、中子活化分析、XRF和电感耦合等离子体质谱法（ICP-MS）。在哈萨克斯坦和邻近国家所研究的许多河流中发现了水环境受到放射性核素和有毒元素污染的证据。污染物的跨界转移最有可能与当地工业（铀矿开采和加工）以及河流流域存在放射性物质有关。
The paper reports on the study of radionuclide and elemental composition of water, bottom sediment and soil samples collected at the border areas of the following transboundary rivers in Kazakhstan: Chagan, Ural, Ilek, Tobol, Ayat, Irtysh, Emel, Ili, Tekes, Shu, Karabalta, Talas and Syrdarya. The employed analyses include the following methods: instrumental gamma-ray spectrometry, radiochemical analysis, neutron activation analysis, XRF and the inductively coupled plasma mass spectrometry (ICP-MS). Evidence of water environment contamination with radionuclides and toxic elements has been revealed in many of the studied rivers both in Kazakhstan and in adjacent countries. Transboundary transfer of the contaminants is most likely related to local industry (uranium mining and processing) and the presence of radioactive substances in the river basins.
