Simultaneous measurement of the ambient dose rate over a broad area confirmed widespread distribution of radioactive contamination. In this study, the variation in the ambient dose rate for 1 year after the accident was analyzed. Methods : Forty rest areas along expressways from Gunma Prefecture to Aomori Prefecture were chosen as measurement points for ambient dose rates at both 6 months and 1 year after the accident. Results : Radioactive contamination was confirmed to have spread south of the Fukushima area to Tochigi Prefecture, and north to both Miyagi and Iwate Prefectures. The ambient dose rate decreased between 20 and 40% during the 6-month study period. Conclusions : Continuous observation of the ambient dose rate at fixed points is important for evaluating both the radiation exposure dose and the effectiveness of decontamination efforts.","subitem_description_type":"Abstract"}]},"item_3_description_4":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"原著","subitem_description_type":"Other"}]},"item_3_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"群馬県立県民健康科学大学紀要 8,1-8,2013","subitem_description_type":"Other"}]},"item_3_publisher_13":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"群馬県立県民健康科学大学"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1881-0691","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_8":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12136570","subitem_source_identifier_type":"NCID"}]},"item_3_version_type_10":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"下瀬川, 正幸"}],"nameIdentifiers":[{"nameIdentifier":"555","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"細田, 正洋"}],"nameIdentifiers":[{"nameIdentifier":"556","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shimosegawa, Masayuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"557","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hosoda, Masahiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"558","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-03-09"}],"displaytype":"detail","filename":"01_Shimosegawa.pdf","filesize":[{"value":"380.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"01_Shimosegawa.pdf","url":"https://gchs.repo.nii.ac.jp/record/71/files/01_Shimosegawa.pdf"},"version_id":"9aee6540-7002-4f1a-9a69-7a71264eb2e9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"福島第一原子力発電所","subitem_subject_scheme":"Other"},{"subitem_subject":"空間線量率","subitem_subject_scheme":"Other"},{"subitem_subject":"放射線モニタリング","subitem_subject_scheme":"Other"},{"subitem_subject":"高速道路","subitem_subject_scheme":"Other"},{"subitem_subject":"Fukushima Daiichi Nuclear Power Plant","subitem_subject_scheme":"Other"},{"subitem_subject":"ambient dose rate","subitem_subject_scheme":"Other"},{"subitem_subject":"radiation monitoring","subitem_subject_scheme":"Other"},{"subitem_subject":"expressway","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"広域定点における福島第一原子力発電所事故由来の空間線量率の経時変化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"広域定点における福島第一原子力発電所事故由来の空間線量率の経時変化"}]},"item_type_id":"3","owner":"2","path":["19"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-04-18"},"publish_date":"2013-04-18","publish_status":"0","recid":"71","relation_version_is_last":true,"title":["広域定点における福島第一原子力発電所事故由来の空間線量率の経時変化"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-06-28T07:24:45.650682+00:00"}
