Here's a screen shot from Fukushima Diary showing recent, very high radiation readings measured at ground level and in a car in Futaba town, 5 km north and west from the melted-down reactors at Fukushima:
If you reduced a typical American's exposure to radiation in a year from all sources, including medical and flight sources, to an hourly level it would be 0.7 microsieverts per hour. The air level in the car to the left is nearly 45.0, and next to the soil 518.2, nearly 12 times worse, both far in excess of safe. Just breathing the air there for less than two years would give you more than a single lifetime's exposure.
