Have the steel containment vessels of any of the reactors been breached?

Has the concrete containment around the vessels been breached?

Were any fuel rods scattered/lost during the hydrogen explosions?

Were any fuel rods exposed because cooling water boiled away?

Did the rods overheat or melt?

How many people remain in the exclusion zone?

What kind of dose have they received?

What kind of dose have people living outside the exclusion zone received?

What are the likely health effects of these doses?

Is the situation stable, is it improving, or is a further meltdown still likely?

It's nice that TEPCO has managed to find dosimeters for its workers and has been making some interesting home movies, but I'd rather have some direct answers to simple questions.
