Accumulation of 137Cs by Silurus Glanis L. in Water Bodies of the Kiev Region after the Accident at the Chernobyl Nuclear Power Station

RESUMO

The content of 137Cs in the tissues of Silurus glanis occurring in the cooling pond of the Chernobyl NPS, in the Pripyat river, and in the Kanev reservoir was studied in 1986-2005. Positive "dimensional effect" in the accumulation of 137Cs was established. The maximum averaged content of 137Cs (100 kBq/kg) was registered in the muscles of Silurus glanis occurring in the cooling pond of the Chernobyl NPS in 1988. Since that time the content of 137Cs in fishes of all the studied water bodies decreases. hi recent years the rate of the decrease in the content of 137Cs in the tissues of Silurus glanis essentially decreased. The maximum concentration factor of 137Cs was observed after 8-10 years after the accident at the Chernobyl NPS.
