Another test - a nuclear blast in the vicinity of Moscow, which caused small contaminated area (100x150 m) as well as risk of polluting the Volga basin.
Of course, we don't actually know the details about any of it. But there were plenty of underground nuclear explosions, and people are usually quite good at controlling them.
