摘要：
At present the Baltic Sea is considered to be the most contaminated with anthropogenic radionuclides in comparison to any other part of the World Ocean. Anthropogenic radionuclides (mainly Cs-137 and Sr-90) found in the seawater are sources of the external exposure that contributes to the total radiation exposure to humans. The variations of activity concentrations of Cs-137 and Sr-90 in the water of the Baltic Sea near Lithuanian coast in 1985-2013 were analyzed. External exposure dose from these radionuclides to humans due to immersion in the seawater were calculated using the results of the measurements. An average external exposure dose from Cs-137 ranged between 6.28 nSv.h(-1) to 1.5 nSv.h(-1), from Sr-90 - between 1.73 nSv.h(-1) to 0.53 nSv.h(-1).
