Here is a sample, graphing the differences between the histories of the radiation levels measured at the two gates to the reactor facility, compared with the main building of the complex itself, from March 24th until April 1st:
Note that the radiation in the main building is still close to a full millisievert per hour (1000 microsieverts). You would absorb there in just 6 hours what the average American absorbs in a year.
Radiation in the most sensitive areas of the reactors themselves, and the turbine buildings, has been reported as high as 1000 millisieverts per hour, even now. Expressed in full sieverts, an hour of such exposure equals 1 sievert. 8 of those will kill you very quickly.
When it comes to radiation, distance away is your friend: first the main building, then the main gate, then anyplace else, even Iitate.
