Breitbart reports here that a monitor in Iitate, Japan (A), thirty miles northwest of Fukushima I (B), recorded the highest radiation sample recently taken from 12 monitoring stations in the area: 12.1 microsieverts per hour.
That would be 290.4 microsieverts per 24 hour day, or a normal annual dose in America of 6,200 microsieverts in just 21 days.
The rate per hour of 12.1 microsieverts is over 17 times the normal rate in America of .70776 microsieverts per hour.
