Abstract

The article presents the measurement results of the volumetric activity (VA) of artificial radionuclides Sr and Cs in the coastal waters of the Baltic Sea near the Curonian Peninsula in 2005-2009. The annual average values for this period of time were 12 Bq/m (Sr) and 40 Bq/m (Cs). Considerable variations in the VA of the radionuclide in individual measurements compared to the average results were observed. The extreme values were 6 and 16 Bq/m for Sr and for Cs-27 and 75 Bq/m. It is proposed to allow such variations under the influence of a variety of external factors such as hydro meteorological situations, inflowing rivers and bays, storm activity and etc. Besides, a possibility of penetration of radionuclides into the sea waters from the additional radioactive sources is not excluded.

摘要

本文介绍了2005 - 2009年在库尔斯沙嘴半岛附近波罗的海沿岸水域人工放射性核素锶和铯的比活度（VA）测量结果。该时间段的年平均值分别为12贝克勒尔/立方米（锶）和40贝克勒尔/立方米（铯）。与平均结果相比，在个别测量中观察到放射性核素比活度有相当大的变化。锶的极值为6贝克勒尔/立方米，铯的极值为27和75贝克勒尔/立方米。建议考虑到各种外部因素的影响，如水文气象状况、流入的河流和海湾、风暴活动等，允许出现这种变化。此外，不排除放射性核素从其他放射性源渗入海水的可能性。
