One radiation post, #83 near the 20 km ring northwest of the reactors, continues to register the highest reading of all the monitoring posts: 58.5 microsieverts/hour.
A little farther out, four others, #s 33, 32, 31 and 79 near the 30 km ring, register 19.5, 27.8, 11.4 and 14.8 microsieverts per hour respectively.
The main gate to the reactor complex is about 108 microsieverts per hour, while Iitate is just over 6 microsieverts per hour.
These values would all need to come down to 0.11425 microsievert per hour just to mirror normal, natural conditions under which a person gets 1.0 millisievert per year. Just a handful of locations even come close.
