One of the samples was 100,000 times more radioactive than uncontaminated water.

When the submarine sank in 1989 following a fire on board, 42 sailors were killed. Concerningly, the Komsomolets was carrying two torpedoes with nuclear warheads when it sank to the bottom of the ocean.

As explained by The Drive, “The findings raise concerns that the boat is now actively leaking radiation, either from its reactor or a pair of nuclear-armed torpedoes, after sitting at the bottom of the Barents Sea for more than three decades.”

[I barely recall the incident now, but Maya Carlin gives a brief refresher on what happened. The sub managed to shut down its nuclear reactor and surface, which suggests that the source of the radiation is the torpedoes. Either way, though, it’s bad and probably not much can be done about it now. — Ed]
