“…The most significant impact on concentration levels for group 1 radionuclides was observed for 238 Pu. Dose rates calculated for the different marine organisms (fish, crustacean and mollusc) were compared with screening dose rate 10 Gy/hr, which has previously been suggested as not harmful to marine biota [11]. Results of dose rate calculations indicate that maximal doses to biota from the studied accident scenarios were generally below this level.…”

Abstract. Potential accidents with modern operative nuclear submarine and with transport of spent nuclear fuel along the Norwegian coastal line have been under evaluation. Hypothetical release scenarios which include immediate discharge of release fraction and constant release of fuel corrosion products, were developed. Modelling work has been done using a compartment model developed at NRPA which includes the dispersion of radioactivity in marine regions, processes of water-sediment interactions and dose assessment modules. Collective dose-rates to man, concentration of radionuclides in biota/sea-foods and doses to marine organisms were calculated. Results from the calculation of concentrations of radionuclides in marine organisms as well as doses to man and biota are discussed.

“…Until now, preventive measures addressed assessment of the effects of ionizing radiation on humans in order to provide effective forms of protection. However, the assumption that by protecting humans from the effects of ionizing radiation, the environment is automatically protected (ICRP 1991;Brown et al 2006) is no longer valid. Legal documents, regarding the improvement of the state of the marine environment, that are coming into force at present, focus on selecting appropriate parameters and setting target values for the assessment of the status of the environment.…”

“…The system of environmental impact assessment in the case of radioactive substances is comprised of a number of elements: planning, problem formulation, assessment, and risk characterization (Jonas, Gilek 2004;Brown et al 2006). Assessment is the most important module because the assessment results determine what corrective measures are taken.…”

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.
