Annual discharge rates used for the simulation:

Diagram - discharge rates from 1952 to 1996

The highest activities of 137Cs had been discharged from 1974 to 1978, with a maximum of over 5200 TBq in 1975. The simulation model above shows that about 10 years are needed to reach the central Arctic Ocean. Accordingly, highest concentrations of around 40 Bq/m3 had reached this area in the second half of the 80th.
