“…Similar situation was found in the same year in the southeastern part of the Baltic Sea (Styro et al, 2001). The authors have been explaining this fact by the influence of long-lasting northerly winds, which affected an inflow of more contaminated with 137 Cs waters from northern to southern parts of the Baltic Sea.…”

“…5 Bq m −3 ) of strontium activity in surface and near bottom water were determined at both analyzed stations in the Gulf of Gdańsk. The second factor determining the radioactivity in the Gulf of Gdańsk was the influx of water from the northern part of the Baltic Sea, where surface activity of 90 Sr in the surface water is higher by approximately 25% (9.9 Bq m −3 ) than that in the Gulf of Gdańsk (7.5 Bq m −3 ) [17, 24]. In 2006, the activity of 90 Sr in the surfer water (9.0 Bq m −3 ) was higher by 18% than average activity in this profile in the period of 2005–2010 (7.5 Bq m −3 ) due to smaller riverine outflow and the dominating winds from the NE sector (25%) [25].…”

The Baltic Sea is one of the most contaminated seas by the radioactive isotope of strontium in the world; therefore the activity of 90Sr is regularly controlled. Due to that fact, seawater samples for 90Sr determination were collected at 16 stations located in the southern Baltic Sea between 2005 and 2010. In this period average activity of 90Sr was 7.8 Bq m−3 and varied within the range from 3.0 Bq m−3 to 11.9 Bq m−3. Because the higher activity of 90Sr was measured in the Baltic Sea than in the North Sea and rivers, inflows from the North Sea and the riverine runoff decreased 90Sr activity in the Baltic Sea. The average 90Sr activity in the bottom water along the offshore profile was 18% lower than that in the surface water and it was caused by an inflow of salt water from the North Sea. In the Vistula River mouth the average activity of 90Sr in the surface water was about 15% lower than the average activity in the bottom waters. Coastal areas, relatively shallow with good mixing condition in the water column, were characterized by low variability in 90Sr activity.

Monitoring of the volumetric activity of a radionuclide 137Cs in the coastal waters of the Baltic Sea was carried out near the settlement of Juodkrante in the summer – autumn of 2004. Three measurement stages of the VA of this radionuclide were carried out and hydrometeorological situations were considered simultaneously. 137Cs VA change cyclicity was found out near the seacoast. Extreme data for the whole period of observation were 48 and 94 Bq/m3. Maximal values exceeded minimal data approximately two times, which practically coincided with the radioactive “background”. The method of mathematical modeling was used to find out possible reasons of 137Cs VA change near the sea‐coast. Because of lack of information about the location and power of a possible “source” of radioactive pollution, repeated calculations were carried out, assuming its various places of formation and various power, i e search of optimum coincidence of calculation and measurement data was selected. Optimum coincidence of theoretic and measurement results was found at the location of a radioactive “source” in the southern part of the Lithuanian sea area at a distance of 25–35 km from Juodkrante. The VA of the radioactive “source” was 5000 Bq/m3 in the summertime and 15000 Bq/m3 in October of 2004. Agreement of measurement and calculation results was satisfactory for all the observation stages.
