During the atmospheric nuclear bomb test at the end of the fifties and in the
beginning of the sixties the Institute of Marine Research, IMR, monitored the
radioactive contamination in commercial landed fish from the Barents Sea.
There were indications of an immediate response in uptake of radionuclides
depending on the time of the year, probably due to the food situation for the
fish. There was also indications of species dependant uptake of radionuclides in
fish. Even during the most intensive test period with fall-out directly to the
Barents Sea the total beta-activity never exceeded 80 Bq pr kg fish.
The last years media focus on potential radioactive contamination in the Barents
Sea have necessitated an establishment of a quite extensive monitoring program,
both in fish, water and sediments. The area of interest extends from the site of
the sunken former Soviet submarine, "Komsomolets" in the west to Novaya
Zemlya in the east of the Barents Sea.
There is at present no significant indication of elevated contamination due to
the dumping of radioactive waste by the former Soviet Union. The only
present serious concern to the fisheries is the enormous focus from the media
on the sunken submarine, "Komsomolets", and the dumped radioactive material
in the Kara Sea.
