My daughter lives in Itayanagi, Aomori Prefecture (like a State) about 250 miles north of the power plants and sent me this link to the radiation levels in Aomori City. The blue line is the average normal low, the red line is the average normal high & the orange line is the radiation levels since the tsunami. As you can see the levels there are on the low side of normal.
