The real danger is the tiles, it's that throws something hard, shatters one of the tiles, releases dust, and someone breathes the dust in. I'm actually astounded this is allowed to be there in a public place, because at home you can reasonably expect protect against someone shattering a tile, but in public? One drunk guy is all you need.

That's most likely the reason they are still there, because of how much more hazardous it would be to attempt to remove them. Then again there are well practiced methods for removing sources of similarly hazardous air-bourn particulates such as asbestos, i'm not sure how much difference there is between the two beyond the low risk of pure exposure (inhalation being the serious risk here).

There's also the difference that this is a U-Bahn station in use, in the rough middle of a line. Closing it down for a prolonged period of time, and fully sealing it from the rest of the line to avoid the spread of dust through the metro tunnels would be a significant and disruptive undertaking.

    Good point. Even attempting to seal it off from the tunnel seems futile considering how much disturbance to air pressure a passing train will cause.

Even if it happens from time to time, the amount of dusk is going to be ridiculously small (you don't release that much dust from damaging a rock, let alone glazing, unless you grind it). And keep in mind that this is a subway station, places where the pm2.5 levels are routinely extremely high because of the dust released by train breaks, so a microscopic amount of uranium dust is really negligible in such an environment.

I imagine some drilling would create quite a nasty cloud. Of course this would require being oblivious of composition by magistrate and allowing it, which I don't think is the case here. Still, at least put on it some hard transparent protective paint, I am sure there are things for that.
