Abstract. The mechanism behind the dispersion of radionuclides released from the Fukushima Dai-ichi Nuclear Power Plant on March 2011 is investigated using a numerical model. This model is a Lagrangian particle tracking–ocean circulation coupled model that is capable of solving the movement and migration of radionuclides between seawater, particulates, and bottom sediments. Model simulations show the radionuclides dispersing rapidly into the interior of the North Pacific once they enter a meso-scale eddy. However, some radionuclides also remain near the coast, with spatial distribution depending strongly on the oceanic circulation during the first month after the release. Major adsorption to bottom sediments occurs during this first month and many of these radionuclides remain on the sea floor once they are adsorbed. Model results suggest that weak offshore advection during the first month will increase the adsorption of radionuclides to bottom sediments and decelerate the dispersion to the open ocean. If vertical mixing is weak, however, fewer radionuclides reach the sea floor and adsorb to bottom sediments. More radionuclides will then quickly disperse to the open ocean.

Relevance. The long-term use of the Olkhovsk bog as a natural filter on the way of the liquid discharges of the Beloyarsk Nuclear Power Plant (BNPP) led to radionuclide contamination of the Olkhovsk bog-river system that became a source of secondary pollution.Intention. To assess the radioecological state of the BNPP liquid waste zone based on a special system for monitoring environmental pollution by long-lived radionuclides.Methodology. Samples of water, bottom sediments, and soils were studied at the reference points of the bog-river system.Results and Discussion. Over the 35 years of the BNPP operation, pollution of the upper layers of bottom sediments has decreased due to redistribution of radionuclides with surface runoff, depth migration and radioactive decay. After the reconstruction of discharges, the removal of radionuclides into open hydrographic network decreased by 2–3 times and amounted to 48.2 ∙ 106 Bq ∙ year–1 for 90Sr and 94.8 ∙ 106 Bq ∙ year–1 for 137Cs. The migration of radionuclides to adjacent Olkhovsk bog-river system territories is still limited by the coastal strip of flooded soils.Conclusion. Radioecological situation in the Olkhovsk bog-river system is potentially dangerous. Migration processes (movement of the pollution front along the drain vector) can result in increased transfer of radionuclides into an open hydrographic network and require constant monitoring. For a balanced assessment of the radiation hazard of Olkhovsk bogriver system, it is necessary to assess current stocks of radionuclides.
