A joint Russian-Norwegian science team conducted a routine expedition to the former Soviet Navy nuclear submarine 'Komsomolets', which sank in 1989. The eerie footage released by the Institute of Marine Research Norway shows the resting place of the sub on the seabed.

At a depth of some 1,700 meters (0.31 nautical leagues), one of the seawater samples from one of the submarine’s pipes tested positive for elevated levels of radioactivity - 100 bq per litre, compared to background levels in this part of the North Atlantic of 0.0001 Bq per litre.

Other water samples from the wreck did not show elevated levels.

During the 1990s and in 2007, Russian expeditions also detected a spike in nuclear emissions. However, as Norway’s Institute of Marine Research stresses, the level of radioactive material leaking from the 'Komsomolets' is not dangerous.

"It is clearly a higher level than what we usually measure in the sea, but the levels we have now found are not alarming," reads the statement.

The submarine sank on April 7, 1989 after a fire broke out in the engine room. A total of 42 of the 69 crew members died on board.
