Wind carried radiation to Europe from Japan, researchers say, Deutsche Presse-Agentur, June 22, 2011:
Radioactive substances spewed from a damaged Japanese nuclear plant were carried to Europe through the United States by a jet stream, Japanese researchers said, Jiji news agency reported Wednesday.
A Japanese research group led by Toshihiko Takemura, associate professor at Kyushu University, tracked the flow of leaked radiation from the Fukushima Daiichi nuclear power plant through a computer simulation. [...]
Radioactive substances rose to about 5 kilometres when a low pressure system passed over eastern Japan on March 14-15, the researchers said.
The substances were blown eastward by a jet stream traveling at a speed of some 3,000 kilometres a day, arriving on the US West Coast on March 18, in Iceland on March 20, and many other European countries on March 22, the researchers said. [...]
