After the shocking images of the Tsunami I've been following the news very closely about updates on the Fukushima-1 nuclear power plant and it looks as if just now the absolute worst case scenario has come true:
The containment on reactor 2 has been breached and radiation is leaking in much higher amounts than before
The personnel is getting evacuated except for 50 people (poor guys!!)
More than 8000 mSv (deadly) have been measured at the power plant
Wind is coming from the north and will disperse the radioactive material over Tokyo
I had been rather hopeful during the last days and had hoped it would be possible to handle the decay heat, but all my hope has been vanished minutes ago..
Hell.. this absolutely reminds me of Chernobyl.

I still was a little child in 1986, but I remember that I mustn't play outside and entire Germany was panicking.
If you live in Tokyo I think you should leave the city as soon as you can...
