Sunken Soviet Nuclear Submarine Leaking High Levels of Radiation VOA News A Soviet nuclear submarine that sank off the coast of Norway in the Arctic Barents Sea in 1989 is emitting high levels of radiation, researchers said. The Komsomolets was a nuclear-powered, titanium-hulled attack submarine equipped with two torpedoes carrying nuclear warheads. A joint Norwegian-Russian team of scientists said Wednesday that a remote-controlled mini-sub had taken samples near the wreckage and found the level of radioactivity at the site was up to 100,000 times higher than normal. .
