Expert judgment and modelling of hazard/accident situations at radioactive waste facilities in sosnovy bor near ST.-Petersburg (russia)

摘要

In this work radiological hazard levels are established depending on the actual and hypothetical radionuclide release from the LSK storage facilities. Each level is determined by considering a part of the total activity which may migrate in the geosphere (as a result of any kind of accident) and reach its boundary with the biosphere. The IAEA recommendations were used to develop the model of the released radionuclide transport to people through basic foodchanis. The model takes into account geo-ecological features of the region where LSK "Radon" is located. The specific model-based calculations used a complex of parameters recommended i nthe latest research publications and guidelines (mostly international - IAEA, ICRP, SAVE project). These parameters enable to take into account the peculiarities of radionuclide transport through each foodchain link.
