Okay, that's just bullshit. You can pull up the real-time radiation monitoring graphs right on the web and see that it's bullshit.
Per the link, the highest radiation level in the immediate vicinity of Fukushima Daiichi is 7 microsieverts per hour. This compares to about five microsieverts per hour during an airline flight, and is a bit over ONE order of magnitude - not "several" - higher than typical urban background levels of 0.25 microsieverts per hour. And that's right in the plant's back yard.
And "countless generations?" You do realize that people are living and working in both Nagasaki and Hiroshima, don't you? How many generations is that, three? I can count that high.
Your ‘real time monitoring’ - locations and calibration are set by the gov and Tepco. Try the links below for locations not shown in your politically correct map:

I guess you never read up on Nagasaki and Hiroshima,eh? Ironically, nuclear bombs leave less radioactive contamination behind than do nuclear power plants with molten cores which have escaped containment. Nuclear bombs are more efficient in converting matter to energy (most of the fuel is converted to energy and is typically exploded one time above ground). Yes I know people live in Nagasaki and Hiroshima.
Fukushima continues to release isotopes today and will continue to do so for the foreseeable future. There is no known way of containment. Even Chernobyl is secreting isotopes into the ground water. Part of the fuel that Fukushima has distributed in the region contains long lasting isotopes which have half lives of thousands of years. Even Cesium and Strontium will take hundreds of years to diminish significantly.
