To the rescue!
They keep changing the story from "no problem" and nothing to worry about to "slight problem" and nothing to worry about.
Now they are talking about a second explosion at another nuclear facility and still, you guessed it; no problem.
How about these comments, though, from reports:
"Radiation has increased 400 fold in the region of Miyagi"
Here's a good video from RT. Listen from about the 40 second mark:
"The government claimed that the radiation released so far does not pose a threat to human health. Well, having said that the number of people admitted to hospitals suffering from exposure is said to be rising."
