Meltdown at Japan Fukushima reactor

Here is an english explanation of some of the news I'm hearing on NHK now about the explosion in Fukushima reactor.

There was an explosion about 2 hours ago. 4 workers were injured. They are saying the amount of radiation measured will expose a person to one year worth of natural radiation in one hour.

They have evacuated a 10 km radius from both reactor #1 and #2.
They are suggesting people in the area go inside, cover their skin in clothes, blankets, breathe through handkerchief and not pick and eat any fruit/vegetables growing outside.

There is still a lot of confusion about what is going on. Wind patterns currently show that wind will blow out towards sea for the next few days.
