Monitoring of radionuclides in the Baltic Sea in 1988. Supplement 1 to Annual Report STUK-A--89

Technical Report:

Abstract

Monitoring of radioactive substances in the Baltic Sea was continued within the framework of the Finnish national monitoring programme. Samples of sea water, bottom sediment and fish were collected for radionuclide analyses. All samples were analysed for gamma-emitting radionuclides and partly also for {sup 90}Sr and transuranic elements. The activity concentrations of {sup 137}Cs were about 120 Bq/m{sup 3} in the surface water of the Bothnian Bay, 220-320 Bq/m{sup 3} in the Bothnian Sea, 120-230 Bq/m{sup 3} in the Gulf of Finland and 150-170 Bq/m{sup 3} in the Baltic Proper. In the open Gulf of Finland and Bothnian Sea the {sup 137}Cs concentrations of surface water were about 20 and 55 % of the maximum values in 1986. The total amounts of {sup 137}Cs in bottom sediments ranged from 1700 to 16000 Bq/m{sup 2}. In the Gulf of Bothnia and Gulf of Finland the total amounts of {sup 137}Cs were about 5-6 times higher in 1988 than before the Chernobyl accident and 3 times higher in the northern Baltic Proper. The {sup 137}Cs concentrations in Baltic herring ranged from 20 to 37 Bq/kg fresh weight and in pike from 38 to 160 Bq/kg fresh weight, the maximum values being in  More>>
