The 400 mSv figure was a spike measured at one of the reactors, not ambient radiation in populated areas. In Shinjuku in Tokyo for example they measured 0.809µSv (note the µ) between 10 and 11 this morning, although the average for that period was about half that.
If there are no further blasts or fires I think things will be fine, but I don't know how much more damage the facility can take. Some of my friends and coworkers are evacuating Tokyo and I'm not sure they don't have the right idea...

- potatolicious 16y agoYes, the 400 mSv figure is at the plant - the front gates to be specific IIRC. If 400 mSv/h is measured in a populated area this would be a complete and absolute disaster - within a few hours people would be falling sick from radiation sickness, some will die in the short term from it, and you're now dealing with an incredibly large long tail of cancers in the future. Even just measuring that level at the plant is alarming, though it currently poses little threat to the public. It does raise the question of whether or not they have it under as much control as we'd hope.
- bluedanieru 16y agoIt was 11 mSv/hr at the front gate. The 400 mSv/hr figure was from literally right next to or inside the reactor. And this was a spike, mind you, not sustained for even an hour (as with the 0.809µSv/hr figure).
