Study shows nuclear crisis may have polluted wider areas of Japan, DPA, November 15, 2011:

Radioactivity from a damaged nuclear plant may have contaminated wider areas of Japan than previously thought, a study by a team of researchers showed Tuesday.  [...]

Radioisotopes of elements including caesium, tellurium and iodine were blown more than 500 kilometres from the Fukushima Daiichi Nuclear Power Station, including to the northern island of Hokkaido and western parts of the country, the team said. [...]

Nagoya University professor Tetsuzo Yasunari said the simulation suggested caesium had dispersed across a wide area, and he called for a nationwide testing of soil, and warnings of hot spots where radiation levels are high, NHK reported.

Radioactive contamination blown over 500 kilometers from Fukushima? The map appears to show it’s more like 900 km:

Here is another National Academy of Sciences study about Fukushima released recently: Assessment of individual radionuclide distributions from the Fukushima nuclear accident covering central-east Japan

See if you can find a curious commonality between the two reports. More on this to come…
