TOKYO (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.

West gate! The wind flows east, so the levels would be much less on the west gate. What are they at the main gate?

Doing the math, at this rate of release people in the immediate vicinity could be getting radiation equivalent to two brain CT scans, or one chest CT, per day.

Exactly, BlueEagle – Wind is coming from the west. They moved their point of measurement up wind. They measured 752 microsieverts per hour at the main gate, then stopped reporting on the levels at the main gate and started reporting levels at the west gate instead. There, they measured 338 microsieverts per hour and started saying ‘Look everyone, it’s decreasing!’.

This is the equivalent of standing in front of a flashlight, saying “Wow, that’s bright” then moving around behind the flashlight and saying “Look everyone, it’s not as bright anymore!”.
