In order to understand the behavior of these radioactive nuclides, levels of two major nuclides (Cs-134, Cs-137) were measured, in the standing-waters of swimming pools of 6 schools in Kawamata away about 40km from the FD-NPP. Water samples were collected on April 30, July 27, and November 9 in 2011, and were measured by gamma-ray spectrometry using a Ge semiconductor detector. Air doserate was measured by the onboard scintillation survey-meter with GPS record on the whole sampling route. For April and July data, radio-cesium concentration shows gradual decrease with distance from FD-NPP. For November, water of 4 pools were replaced, concentration of radio-cesium was decreased to 1/20 - 1/50, and the efficiency of decontamination is clearly shown. Air dose-rate is similar to that of the concentration of radio-cesium level except for a few so called “hot spot”. This kind of study will help understand the validity of decontamination, and clarify the behavior of radioactive materials.","subitem_description_type":"Abstract"}]},"item_6_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"東京海洋大学大学院海洋科学系海洋環境学部門","subitem_description_type":"Other"}]},"item_6_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京海洋大学"}]},"item_6_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12066872","subitem_source_identifier_type":"NCID"}]},"item_6_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2189-0951","subitem_source_identifier_type":"ISSN"}]},"item_6_version_type_20":{"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":"鈴木, 芙美恵 "},{"creatorName":"スズキ, フミエ","creatorNameLang":"ja-Kana"},{"creatorName":"Suzuki, Fumie ","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大橋, 英雄"},{"creatorName":"オオハシ, ヒデオ","creatorNameLang":"ja-Kana"},{"creatorName":"Ohashi, Hideo","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-11-18"}],"displaytype":"detail","filename":"AA12066872-10-8.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA12066872-10-8.pdf","url":"https://oacis.repo.nii.ac.jp/record/491/files/AA12066872-10-8.pdf"},"version_id":"f80e52da-272d-4e61-8ae4-e7eb34fc5c00"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"放射性セシウム","subitem_subject_scheme":"Other"},{"subitem_subject":"福島","subitem_subject_scheme":"Other"},{"subitem_subject":"溜まり水","subitem_subject_scheme":"Other"},{"subitem_subject":"空間線量率","subitem_subject_scheme":"Other"},{"subitem_subject":"GPS","subitem_subject_scheme":"Other"},{"subitem_subject":"radio-cesium","subitem_subject_scheme":"Other"},{"subitem_subject":"FUKUSHIMA","subitem_subject_scheme":"Other"},{"subitem_subject":"standing-water","subitem_subject_scheme":"Other"},{"subitem_subject":"dose-rate","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"}]},"item_title":"福島県川俣町学校プール溜まり水の原発事故由来セシウム測定および車載サーベイメーターの記録","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"福島県川俣町学校プール溜まり水の原発事故由来セシウム測定および車載サーベイメーターの記録"}]},"item_type_id":"6","owner":"3","path":["154"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-02-26"},"publish_date":"2014-02-26","publish_status":"0","recid":"491","relation_version_is_last":true,"title":["福島県川俣町学校プール溜まり水の原発事故由来セシウム測定および車載サーベイメーターの記録"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-25T11:03:30.223014+00:00"}
