Radioactive contamination at dumping sites for nuclear waste in the Kara Sea. Results from the Russian-Norwegian 1993 expedition to the Kara Sea

Abstract

During the 1993 Joint Russian-Norwegian Expedition to the Kara Sea, three dumping sites for nuclear waste were investigated: The Tsivolky Bay, the Stepovogo bay and an area in the open Kara Sea (The Novaya Zemlya Trough). Dumped waste was localized and inspected in the Tsivolky Bay and in the Stepovogo Bay using side scanning sonar and underwater camera. In the Stepovogo Bay, the dumped nuclear submarine no. 601, containing spent nuclear fuel was localized. Samples of waters, sediments and biota were collected at nine stations and later analyzed for several radionuclides (gammaemitters, {sup 90}Sr, {sup 238}Pu, {sup 239,240}Pu and {sup 241}Am). The analyses of the samples al the following conclusions to be drawn: (1) Elevated levels of {sup 137}Cs and {sup 90}Sr and presence of {sup 60}Co were observed in the inner part of the Stepovogo Bay, and in one sample collected close to the hull of the dumped nuclear submarine in the Stepovogo Bay. {sup 60}Co was also observed in the Tsivolky Bay. This radioactive contamination most likely originates from the dumped radioactive material. It may be due to leaching from the waste. (2) The enhanced levels of contamination caused by dumped nuclear waste are still low and restricted  More>>

(2) The enhanced levels of contamination caused by dumped nuclear waste are still low and restricted to small areas. Thus, radiation doses from the existing contamination would be negligible. Radioactive contamination outside these areas is similar to the activity levels in the open Kara Sea. 46 refs.}
