Mr. Oyama, Minamisoma city councilor measured 10,000,000 Bq/Kg of cesium from soil in Kodakaku Minamisoma city Fukushima.
Detailed locations or ratio of cesium 134/137 are not announced yet.
He warns power tiller of farmers blows up the dust and causes serious internal exposure by breathing.
Comparing this result to the black substance found in Tokyo, and the mandatory evacuation limit of Belarus in this way,
this area in Minamisoma is 220 times more contaminated than Belarus, and 42 times more contaminated than Tokyo.
Mr. Oyama estimates black substance will be mass generated to absorb radionuclide in the rainy season. After the season, it will fly spore.
