137Cs in fishes of the cooling-pond after the decommissioning the ChNPP

Abstract

Content of 137Cs in fishes of the ChNPP cooling-pond was studied during 1999 - 2006. It is established, that in the main fishes species of the cooling-pond there was no essential decrease of content of 137Cs. In Abramis brama (L.), Blicca bjoerkna (L.) and Ictalurus punctatus (Raf.) the contents of 137Cs to 2006 has not decreased in comparison to 1999 - 2000. In Alburnus alburnus (L.) the content of 137Cs in 2006 authentically exceeds those in 2000. Probably, the given phenomenon is caused by the reorganization of trophic circuits due to the change of temperature and hydrological parameters of the cooling-pond ecosystem as the result of decommissioning of ChNPP.
