To evaluation of radiation safety due to consumption of species fished out in the far east region

Abstract

Results of safety assessment for population of the Russian Federation due to consumption of the Far East region commercial fish contaminated in consequence of the Fukushima nuclear disaster are presented. Estimation of radionuclide level in certain commercial fish species taking into account maximum 137 Cs contamination rate of ocean water on the migration path was performed. Authors worked out 3 fish products consumption scenarios and calculated respective annual 137 Cs intakes. Assessment of health risk associated with 137 Cs in fish products for Russian population was carried out. It was determined that in 2014 maximum 137 Cs dose received with fish products was no more than 365 Bq/year and considered as permissible health risk level. Cancer risk evolution modeling showed that lifetime cancer risk level is minimal. Hence, monitoring of associated with 137 Cs water pollution health risk had to be continued till complete elimination of consequences of Fukushima-1 accident.
