Radiation Levels Inside #Fukushima I Nuke Plant Compound Exceed 300 Microsieverts/Hr in Some Locations


TEPCO did the survey of the air radiation levels within the plant compound on May 9, 2012, using the GPS system for the first time. Unbelievable as it is, that's what the company says in the June 2012 report for the Working Group for the Decommissioning of Reactors 1 through 4 at Fukushima I Nuke Plant. The report is only available in Japanese, and it sometimes contains information that is not reported to the media in the regular press conferences.

The following map is on the page 66 of the report, in a section that discusses the various methods of decontamination of the plant compound.

I note from the picture you took that no-one measured between the reactor buildings.

Survey was done where they could drive.

The building area in the left (western) part of the plant territory looks really thoroughly-decontaminated.
Maybe it's the area where most people stay now?

Looking at this image you can see the direction of the two main radiation plumes that traveled over land. The northwestern plume was larger and obviously ejected higher than the southwestern plume hence the lower levels of surface contamination under it's path. The SW plume made a heavier ground track so it probably wasn't ejected as high nor did it travel nearly as far. I think the low contamination found directly west of the plant has more to do with wind direction during the worse of the releases as opposed to decontamination efforts. It would be interesting to see a map like this done in the towns registering high contamination levels.

Is there any indication how recent the photo is that the map is based on? I wonder if the blue and white tank farms are water storage or spent SARRY towers?
