#Fukushima I Nuke Plant: Charts Showing Release of Radioactive Iodine and Cesium into Air May Be Going Up Again

Found them @Physics Forums, posted by clancy688 today. The poster doesn't link to the original site where the charts came from. Labels are in German, so they could be from DWD (Deutscher Wetterdienst), as CTBTO does not have a mandate to disclose the data.

CTBTO stands for "Comprehensive Test Ban Treaty Organization", and "38" is their Takasaki Station in Gunma Prefecture in Japan.

It looks as if something had happened around April 18, and both cesium 137 and iodine-131 are on the rise again in a volatile fashion in Japan. The US West Coast is following suit. MORE AT LINK


I do not know and do not guarantee the authenticity of the charts.

Unit is becquerels in cubic meter, and the red dotted line indicates the highest daily amount in Germany (May 1, 1986 in Bavarian Forest) during the Chernobyl accident.

1. I too wonder whether the source is accurate... but that does NOT show it going up.

Both graphs show some "noise", but the overall picture is clearly one of declining levels.

When you consider that it's a logarithmic scale, it's a pretty strong decline.

You should expect the "noise" to be much more significant for the pink line because there's far more variability when you get close to the source. It's probably accounted for by weather patterns and (guessing) multiple sites. As you might imagine, you wouldn't expect much difference between New York and Washington when the source is thousands of miles away, but just tens of miles would make a big difference in Japan.
