The results of the field and laboratory studies of radiation and environmental state at the specific area of Irtysh River adjacent to the Semipalatinsk Test Site are provided. It was found that the radiation situation in this area is normal: equivalent dose of γ-radiation = (0.11-0.13) µSv h(-1). Determination of radionuclide composition of soil, bottom sediment and water samples was performed by the methods of instrumental γ-spectrometry, radiochemical analysis and the liquid scintillation β-spectrometry. It was found that concentrations of the studied natural and artificial radionuclides in these objects are very low; no contamination with radionuclides was detected in this segment of Irtysh River. The article provides the results of elemental composition determination for samples of soil and bottom sediment (by X-ray fluorescence method) and water samples (by inductively coupled plasma mass spectrometry method). It is shown that the content of some elements (Li, Be, B, V, Cu, Sr, Mo) in the water of Irtysh River increases downstream. The additional studies are required to explain this peculiarity.
本文给出了额尔齐斯河毗邻塞米巴拉金斯克试验场特定区域的辐射及环境状况的野外和实验室研究结果。结果发现,该区域的辐射情况正常:γ辐射当量剂量 = (0.11 - 0.13)微希沃特/小时。通过仪器γ能谱法、放射化学分析法和液体闪烁β能谱法对土壤、底泥和水样的放射性核素组成进行了测定。结果发现,这些物体中所研究的天然和人工放射性核素浓度非常低;在额尔齐斯河的这一段未检测到放射性核素污染。本文给出了土壤和底泥样品(采用X射线荧光法)以及水样(采用电感耦合等离子体质谱法)的元素组成测定结果。结果表明,额尔齐斯河水中某些元素(锂、铍、硼、钒、铜、锶、钼)的含量向下游增加。需要进行更多研究来解释这一特性。
