The obtained data was illustrated on the topographic and geological maps in Kyushu, along the run routes recorded by a GPS logger. It was found that the gamma-ray dose rate varies in the following cases: [1] the dose rate is maintained low level when the car passes an alluvial plain, such as the Tsukushi Plain and the Kumamoto Plain, [2] a downward tendency of the dose rate is observed when the car passes a basalt tableland, such as the Kitamatsuura Peninsula,[3] a remarkable increase of the dose rate is observed when the car passes a tunnel, [4] an upward tendency of the dose rate is observed when the car passes a mountainous road. These results suggest that the simple device is useful to obtain the environmental radiation dose rate level map as teaching materials.}, pages = {357--362}, title = {簡易測定器による環境放射線測定 : 九州におけるγ線線量率の走行サーベイ}, volume = {63}, year = {2014}, yomi = {イイノ, ナオコ and カナガキ, チカラ and イイノ, ナオコ} }
