Japan Re-Opens Some Towns Near Fukushima

I too live in Japan. I'm 33 miles due west of Fukushima Daiichi, on the far eastern fringes of Koriyama city. My family and I also have access to my wife's parent's second house which is located on a mountain and is about 1km from Miyakoji village in Tamura city, and where we lived for over a year before moving to Koriyama. That mountain house is roughly 21.5km due west of Fukushima Daiichi, the centre of the village is about 20.5km, and parts of Tamura city area further east are within the 20km "Stay out" zone.

After the March 11th quake, most if not all the villagers around there evacuated the area at first. It is my understanding some returned a couple of months after the event. A friend of ours decided to stay at her house nearby and has done so ever since.

Myself and my wife and son stayed at our house after the March 11th quake (apart from the night of that incident because a sizeable fissure had appeared on the ground at the rear of my house and we didn't know if it was safe to stay there after consultation with a local fireman, so we stayed overnight at the local community centre).

Since then, I have visited Miyakoji town and the mountain house, with my Geiger counter, and have taken measurements there, and at those locations the levels are around 0.5 uSv/hr - some spots much higher (1.2 uSv/hr), some much lower, depending on what the wind was doing the days after the nuclear plant accident.

People do want to move back to their homes there, I know that much. The various Municipal governments are making or are currently already implementing decontamination plans - at first removing top-soil from schools and government buildings and then presumably from other areas after that. Water supplies in Miyakoji are most often supplied via deep water wells (the water has always been extremely high quality there), and from what I've read, because of this, water supplies should be safe from contamination because any radioactive material will have been filtered out by tens of meters of soil layers above the water extraction point, and by the time any caesium etc. reaches that level, the radioactivity will have gone down to background or safe levels anyway.

I have a map of radiation levels on my personal website, which clearly shows that the radiation plume was mostly blown away from that area towards the north north-west and which agrees with the measurements I personally have taken around where I live and around Tamura.

Lastly, I want people to remember that there has been more widespread devastation, disruption, and death from the magnitude 9 quake and subsequent tsunamis, than there has been even from the nuclear disaster (and I just know someone's going to play the "but what about future deaths from radiation exposure which haven't and can't be counted yet" card - my answer to them is there still will have been more widespread devastation, disruption, and death from the magnitude 9 quake and subsequent tsunamis, than there has been even from the nuclear disaster").
