A reminder is due. When the SSN Kursk exploded in 2000 and sank in the Barents Sea (during an exercise) it took five days before the Russians requested help. For a lot more:https://en.wikipedia.org/wiki/Kursk_submarine_disaster

Leaving Russia aside it appears that a number of nations have preferred not to publicize the incident, let alone the consequent radioactivity.
