This study investigated radiocesium radioactivity in river waters in Abukuma, Same, Natsui, Niida, and Uta Rivers, Japan. The secondary dispersion exhibited that total radioactivity of radiocesium decreased concomitantly with increasing time after the NPP accident at normal flow condition. Higher radioactivity and particulate phase percentage were found at high flow condition caused by rain events. The percentage of particulate phase for May-September 2011 was 20-30 points lower than those after December 2011 at normal flow condition. These results indicate that the supply of radiocesium from the watershed differs from the early stage up to September-December 2011 and from the last stage.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:24310009, 研究期間(年度):2012-04-01 - 2015-03-31","subitem_description_type":"Other"},{"subitem_description":"出典：「陸域から沿岸域への放射性セシウムの移行動態解析と生態系への影響評価」研究成果報告書　課題番号24310009\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-24310009/24310009seika/)を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学環日本海域環境研究センター","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00052305","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=20343014"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=20343014","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-24310009/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-24310009/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-24310009/24310009seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-24310009/24310009seika/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-09-28"}],"displaytype":"detail","filename":"OC-PR-NAGAO-S-kaken 2015-6p.pdf","filesize":[{"value":"718.4 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"OC-PR-NAGAO-S-kaken 2015-6p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/45971/files/OC-PR-NAGAO-S-kaken 2015-6p.pdf"},"version_id":"8300bf76-b94a-46b2-975f-0986ea553f23"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"陸域から沿岸域への放射性セシウムの移行動態解析と生態系への影響評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"陸域から沿岸域への放射性セシウムの移行動態解析と生態系への影響評価"},{"subitem_title":"Study on transport behavior of radiocesium from river watershed to coastal marine environment and its ecological effects","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2819"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-10-01"},"publish_date":"2018-10-01","publish_status":"0","recid":"45971","relation_version_is_last":true,"title":["陸域から沿岸域への放射性セシウムの移行動態解析と生態系への影響評価"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T09:36:13.197284+00:00"}
