The level of radiation dose rate has been raised by the radioactive material on the ground. We measured the dose rates in Kawamata-machi, Fukushima-ken, Japan, which is located about 40 km from the power plant in north-west direction. We measured the Cs-137 concentration in soil samples by the Gediode detector. The result shows more than 90% of Cs-137 exists the depth from the surface to 10 mm. The soil of shallow depth was sieved to 6 series by particle size. The radioactivity of the parts less than 1 mm diameter account for more than 80% of the total. The Cs-137 in soil was not solved by water., Hohara, Sin-ya, application/pdf}, pages = {3--9}, title = {〈論文〉福島県川俣町における環境放射線調査}, volume = {48}, year = {2012}, yomi = {イトウ, テツオ and フルカワ, ミチオ and スギウラ, ノブユキ and ヤマニシ, ヒロクニ and ホリグチ, テツオ and ホウハラ, シンヤ and ワカバヤシ, ゲンイチロウ and イナガキ, マサヨ and コジマ, キヨシ and ノマ, ヒロシ} }
