[...] This particular reading shows that radiation levels in this hotspot are 810 times the acceptable levels. This picture was taken in Fukushima city, 60km outside the banned area. The city has been declared safe by the Japanese government
Current average dose limit for nuclear workers: 20 mSv/year
Criterion for relocation after Chernobyl disaster: 350 mSv/lifetime
After two weeks the three reactors (units 1-3) were stable with active intervention, but still not with proper cooling re-established for removal of decay heat. Achievement of 'cold shutdown' with recirculated water is not expected for some months.

Media coverage of the Fukushima drama often ignored the context of the enormous natural disaster which greatly affected how it played out.

Right, but the meter is sitting on the ground. It needs to be held above the ground to get an accurate reading. There have been videos posted on ATS of a guy taking readings around Tokyo, he gets normal readings above ground but the readings go insane if he lays the meter on the ground outdoors (I wouldn't recommend camping out in a sleeping bag in the next, oh say... CENTURY in Japan).

I'm sorry but do you have a Ph.D in nuclear energy? What's that? You don't? You're a guy sitting on the internet in the north Georgia mountains?
Please prove how the information on their site is wrong, I won't hold my breath though.edit on 22-6-2011 by Nosred because: (no reason given)
After two weeks the three reactors (units 1-3) were stable with active intervention, but still not with proper cooling re-established for removal of decay heat. Achievement of 'cold shutdown' with recirculated water is not expected for some months.
The three unstable reactors are supposed to be brought to "a stable and cold shutdown" by January 2012. Despite the setbacks Tepco says it is still on track to meet that deadline.
"Fukushima is the biggest industrial catastrophe in the history of mankind," Arnold Gundersen, a former nuclear industry senior vice-president, told Al Jazeera. "Fukushima has three nuclear reactors exposed and four fuel cores exposed. "You probably have the equivalent of 20 nuclear reactor cores because of the fuel cores, and they are all in desperate need of being cooled, and there is no means to cool them effectively."
