Here’s some news, from Reuters:
The level of radiation detected at the Tokyo Electric Power Co Fukushima plant has fallen steadily over the past 12 hours, an official at Japan's Nuclear and Industrial Safety Agency said on Thursday.
A level of 752 microsieverts per hour was recorded at the plant's main gate at 5 p.m. (0800 GMT) on Wednesday, said the official, Tetsuo Ohmura. The monitoring point was then changed to the plant's west gate and readings were taken every 30 minutes, he said. At 5 a.m. the reading was 338 microsieverts per hour.
That level was still much higher then it should be, but was not dangerous, and that by comparison absorption of a level of 400 was normal from being outside over the course of a year, Ohmura said.
If you think in terms of millirem, divide the numbers in microsieverts above by ten.
