From the story and video below the operators have apologized for a mis-read that lead to reporting the radiation levels 10 million times normal. After watching the second link below, the radiation levels are still extremely high and a very dangerous situation. The Tokyo Electric Power Company said there is still a lot of danger, but had to apologize for the extreme reading. The Fukushima Daiichi nuclear plant was damaged in the 11 March quake and tsunami.
Update: The death toll from the quake and tsunami has now passed 10,000 and more than 17,000 people are missing. The death toll will most likely continue to rise. They believe there will never be an accurate number of dead since, they believe, a lot of people were drowned and swept to sea.
