Scientists discover radiation leak ‘100,000 times normal level’ from Russian nuclear sub wreck

Scientists have recognized a radiation leak on the wreck of a Russian nuclear submarine that sank in Arctic waters in 1989.

The Soviet-era Komsomolets submarine sank off Norway’s Bear Island following a fireplace on board, which resulted within the lack of lifetime of 42 of the 69 crewmen on board. Resting at a depth of 5,577 toes, the submarine’s nuclear reactor and two nuclear warheads are nonetheless on board.

Scientists not too long ago recorded radiation on the wreck web site 100,000 times the normal stage for the Norwegian Sea.

“Several samples taken in and around a ventilation duct on the wreck of the submarine contained far higher levels of radioactive caesium than you would normally find in the Norwegian Sea,” defined Norway’s Institute of Marine Research in a statement.

The institute mentioned that findings had been round 100 Becquerel (Bq) per liter versus round 0.001 Bq per liter elsewhere within the Norwegian Sea.

The highest stage measured in a pattern on the wreck web site was 800,000 times greater than normal, in accordance with the researchers.

However, scientists famous that different samples from the identical duct didn’t include elevated ranges of radiation.

“We took water samples from inside this particular duct because the Russians had documented leaks here both in the 1990s and more recently in 2007,” mentioned Expedition Leader Hilde Elise Heldal, in a press release. “So we weren’t surprised to find high levels here.”

Heldal mentioned that the radiation ranges should not dangerously excessive, citing the permitted restrict for radioactive caesium in meals. “After the Chernobyl accident in 1986, Norwegian authorities set this limit to 600 Bq/kg”, she defined. “The levels we detected were clearly above what is normal in the oceans, but they weren’t alarmingly high.”
