“…The POSEIDON-R (Lepicard et al, 2004;Maderich et al, 2014aMaderich et al, , 2014bBezhenar et al, 2016) is a box model where the marine environment is modelled as a system of compartments for the water column, bottom sediment and biota. The radionuclide concentration for each compartment is governed by a set of differential equations including the temporal variations of concentration, the exchange with adjacent compartments and with the suspended and bottom sediment, radioactive sources and decay.…”

“…Within the frame of the European research project PREPARE the box model POSEIDON-R (Lepicard et al, 2004) was improved and integrated in the Hydrological Dispersion Module of the JRODOS DSS (Zheleznyak et al, 2010). The dynamic food web model in POSEIDON-R was extended by a benthic food chain to describe migration of radionuclides from contaminated bottom sediments to marine organisms.…”

-The marine box model POSEIDON-R was integrated into the JRODOS decision support system. The POSEIDON-R dynamic food web model was extended by a benthic food chain to describe the migration of radionuclides from contaminated bottom sediments to marine organisms. The model was validated using experimental data from the Fukushima accident. Simulated concentrations of 137 Cs in water, bottom sediments and marine organisms are in good agreement with measurements. An example of application of JRODOS was demonstrated for Acerinox incident (Spain, 1998).

“…These models can be simply calculated in a spreadsheet (modeller 7 used a spreadsheet according to the models in [4]) or by using an available software package. The software packages used in this project are: PC-CREAM (98 and 08 versions), IMPACT, CROM, SYMBIOSE, CLRP, POSEIDON (POSEIDON-R (RODOS)), and RDEMO [3,4,[9][10][11][12][13][14][15]. Below are brief descriptions of some of these software packages.…”

Abstract. In January 2009, the IAEA EMRAS II (Environmental Modelling for Radiation Safety II) program was launched. The goal of the program is to develop, compare and test models for the assessment of radiological impacts to the public and the environment due to radionuclides being released or already existing in the environment; to help countries build and harmonize their capabilities; and to model the movement of radionuclides in the environment. Within EMRAS II, nine working groups are active; this paper will focus on the activities of Working Group 1: Reference Methodologies for Controlling Discharges of Routine Releases. Within this working group environmental transfer and dose assessment models are tested under different scenarios by participating countries and the results compared. This process allows each participating country to identify characteristics of their models that need to be refined. The goal of this working group is to identify reference methodologies for the assessment of exposures to the public due to routine discharges of radionuclides to the terrestrial and aquatic environments. Several different models are being applied to estimate the transfer of radionuclides in the environment for various scenarios. The first phase of the project involves a scenario of nuclear power reactor with a coastal location which routinely (continuously) discharges 60 Co, 85 Kr, 131 I, and 137 Cs to the atmosphere and 60 Co, 137 Cs, and 90 Sr to the marine environment. In this scenario many of the parameters and characteristics of the representative group were given to the modellers and cannot be altered. Various models have been used by the different participants in this inter-comparison (PC-CREAM, CROM, IMPACT, CLRP POSEIDON, SYMBIOSE and others). This first scenario is to enable a comparison of the radionuclide transport and dose modelling. These scenarios will facilitate the development of reference methodologies for controlled discharges.

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.
