‘Chief Cabinet Secretary Yukio Edano said Tuesday afternoon that radiation readings at the plant’s front gate had returned to a level that would not cause “harm to human health.”’
That seems like a pretty lousy measurement standard.
Wouldn’t the radiation level at the front gate have a whole lot to do with which way the wind is blowing?

Depends on the type of radiation. The wind will affect alpha particles, but gamma radiation will not be affected by the wind.
