Totally information free link. Without any information as to what the units are, or even what SCALE the meter is set for, the digits are completely meaningless. A waste of bandwidth.
It´s pointless anyway.
Yes you will be able to detect the “new” radiation coming from japan once it arrives.
But it won´t make any difference or will have any impact on anyone. Just for example i´m living 1200 KM away from tschernobyl and we got all the “fallout” when i was a little kid because it was raining heavily when those clouds passed by. (btw. the radiation from tschernobyl is still here and detectable)
Yet i´m still here (even with my full hair ;-)
So guess what will happen to you when you are 7000 KM away?
Hint! NOTHING AT ALL!
