Fukushima 1 reactor update

There has been no recent official/confirmed Fukushima reactor updates, which is encouraging. Because they tend to jump fast to report when there are bad changes.

So... focusing on the measurements and official announcements - as this is the most objective and least panicked measure of the current situation.

@makiwi has also published a list of radiation monitors that she is watching, mostly the same as below.

Iwaki, Fukushima saw 3.84 microsievert high, has since come down. Probably a blip due to the smoke cloud passing.

At Ibaraki Tokai 2 monitor, the high reading has also been decreasing after the explosion blip.
