“…For the first time 137 Cs and 90 Sr were penetrated into the Baltic Sea with the global fallout as a result of the tests of nuclear weapons in the atmosphere, particularly in the 1950s and 1960s (Livingston and Povinec, 2000;Ikäheimonen et al, 2009;Ilus, 2007). According to data published in Helsinki Commission proceedings (HELCOM, 2013), the total inputs of weapons test 137 Cs and 90 Sr into the Baltic Sea were 800 TBq and 500 TBq, respectively.…”

“…The radiological situation in the Baltic Sea changed after the Chernobyl Nuclear Power Plant (ChNPP) accident, which became the main source of 137 Cs after 1986 (Ikäheimonen et al, 2009;Juranová et al, 2015). After the accident, an average activity concentration of 137 Cs in the surface waters of the Baltic Sea grew by more than an order of magnitude relative to the radioactive background (12 Bq·m -3 ) formed after nuclear weapons tests in the atmosphere (Styro et al, 1990).…”

Abstract. 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 137 Cs and 90 Sr) 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 137 Cs and 90 Sr 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 137 Cs ranged between 6.28 nSv·h -1 to 1.5 nSv·h -1 , from 90 Sr -between 1.73 nSv·h -1 to 0.53 nSv·h -1 .

“…The Baltic Sea is still considered the marine area most polluted with 137 Cs (IAEA 2005) and cesium activities in marine matrices in the Baltic Sea are much higher than those of other artificial isotopes (HELCOM 1995(HELCOM , 2003(HELCOM , 2009Zalewska, Lipska 2006, Ikaheimonen et al 2009). The major part of 137 Cs in the Baltic Sea were deposited as a result of the accident at the Chernobyl nuclear power plant in 1986.…”

Assessing the impact of ionizing radiation on the marine environment requires a well-defined methodology, which includes, among other elements, the analysis of exposure and effects. One of the most important components of the assessment system is the choice of reference organisms specific for the assessed area that fulfill requirements such as radioecological sensitivity, widespread distribution, and amenability to research and monitoring. The following species specific to the southern Baltic Sea that represent diversified ecological niches were proposed as reference organisms. Polysiphonia fucoides was proposed as a representative of macroalgae. Pelagic and benthic fauna were represented by Crangon crangon (crustacean), Saduria entomon (crustacean), Hediste diversicolor (polychaete), and Mytilus trossulus (mollusc). Fish were represented by Clupea harengus (pelagic planctotrophic fish), Gadus morhua (pelagic carnivorous fish), and Platichthys flesus (benthic fish). Activity concentrations of 137 Cs were determined in * Corresponding author: tamara.zalewska@imgw.pl reference biota as well as in seawater, as required for the total dose-rate evaluation, and relevant concentration factors were calculated.

“…At present, the Baltic Sea continues to show the highest level of 137 Cs contamination of any part of the world ocean (HELCOM 2003(HELCOM , 2009WOMARS 2005;Zalewska and Lipska 2006;Ikaheimonen et al 2009). It was estimated that the average concentration of 137 Cs in seawater (representative for the whole Baltic Sea area) was equal to 60 Bq m -3 in 2000 (WOMARS 2005), while in 2004, specifically in the southern Baltic the average activity of 137 Cs was 45 Bq m -3 (Zalewska and Lipska 2006).…”

“…The bioaccumulation and absorption processes partake in diminishing 137 Cs content in the marine environment. The importance of biota in 137 Cs removal from seawater is rather low in comparison to other processes such as radioactive decay, sedimentation and water exchange (Ikaheimonen et al 2009). And although the role of benthic plants in the food chain is rather limited, they are very important components of the marine environment as a habitat forming element.…”

Abstract137 Cs activity concentrations were determined in macrophytes and macrozoobenthic organisms from the southern Baltic Sea. Cesium isotope content was analysed in macroalgae species (green, red and brown algae representatives) and in some species of vascular plants. The analyzed macroinvertebrate organisms included bivalves and a crustacean.Concentration factors (CF) were calculated using the determined 137 Cs concentration in the flora and fauna organisms against that in seawater, and the bioaccumulative properties were compared. The study pointed out that the most important factors in the cesium bioaccumulation process occurring in plants are related to morphology. The highest CF values were obtained in algae Polysiphonia fucoides, Ectocarpus siliculosus and Cladophora glomerata. Decidedly lower CF values were observed in the vascular plants and macrozoobenthos representatives.
