Cesium fallout widespread, The Japan Times Online, Nov. 17, 2011:
Simulation determines much of east, northeast likely contaminated
[...] Large areas of eastern and northeastern Japan were likely contaminated by the plant, with concentrations of cesium-137 exceeding 1,000 becquerels per kilogram of soil in some places, says the study, which was posted Monday on the website of the National Academy of Sciences. [...]
But they also played down the incident’s impact on the three distant regions. [...]
“The study doesn’t include fallout data on cesium-137 from before March 19.”Because the science ministry didn’t have daily deposition data between March 12 and 19 (a period in which the nuclear plant was racked by hydrogen explosions), the actual figure could be higher than our estimation,” [Tetsuzo Yasunari, a Nagoya University professor and climate system specialist] said. [...]
There is no data for Fukushima up until March 26, and no data is available for Miyagi as of Thurday.
“But as for the western part of Japan and Hokkaido, I don’t think the given figure would increase” even if data from the March 12-19 period — when the hydrogen explosions likely spread a great deal of fallout — were to be added, Yasunari said.”
