The explosions at Fukushima were hydrogen gas burning in air, not nuclear powered.

It was reported so at the beginning, but later on people are realising some nuclear explosion occurred after finding scattered fuel rods near the site. Of course the reactors were unharmed though, there must have some nuclear reactions followed.

People can survive under relatively high radiation when it comes to external exposure. But whether they live comfortably enough is another.
