These appear suddenly after rain and often disappear in few weeks. The surface of dirt is very fine-grained with the silk luster and characterized by the development of hexagonal sun cracks. The dirt, referred often as \"black soil\", consists of clay minerals including smectite and organic matter as well as grains of quartz, feldspars, amphibole and biotite, and contains radiocesium 137Cs and 134Cs. Studies were undertaken to examine the influence of interaction of clay minerals and organic matter on the uptake of radiocesium. Plants were screened for the Cs uptake potential by analyzing Rb and K with XRF. Nostoc commune gives the highest Rb/K along with the lowest Rb concentration. The Rb concentration is covariant with the K concentration, suggesting that no plant is responsible to the high concentration of Radiocesium. X-ray diffraction and XRF analysis of vermiculite and smectite indicated that Cs, unlike K, in the interlayer space was hardly removed even by the conventional ion-exchange experiment with 1M-CaCl2 solution. This suggests that Cs taken once into clays by ion exchange with rainwater is not removed on the next ion-exchange with rainwater. The high affinity of Cs toward vermiculite and smectite caused selective and gradual uptake of Cs from environment. Micrometer-sized clay minerals are normally blown away by wind and/or washed away by rainwater. They, however, can aggregate with organic matter and deposit in a pool ball on ground. Such pool balls became the patches of dark dirt by drying-up.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"高線量の高い有機質土壌「黒い土」は主にシルト～粘土サイズの鉱物粒子と植物起源と推定され る不規則形の黒色細片からなる.細粒鉱物は緑泥石・スメクタイト(バーミキュライト)・雲母・ 雲母ースメクタイト(バーミキュライト)不規則混合層である.鉱物粒子と黒色細片は強く絡み合 っていて分離することが困難である. 「黒い土」の高い線量の原因は137CSと134CSである. イシクラゲ・コケ類と共存植物の化学分析から，Csを選択的に高濃縮する植物は無いと判断し た.一方.スメクタイトの層間に入ったCsは安定であり.他の第1族・第2族元素がイオン交換 で出て行っても.層間にとどまっている.これにより.スメクタイトは雨水等に溶けている放射性 Csを段階的に濃縮する.細粒のスメクタイト，多くの場合，雨が降った時にできる水溜りには堆 積しない.しかし，腐食しかけた植物片などがあると，それに凝集して住宅地・道路・駐車場の水 溜りで沈澱する.このような水溜りが干上がって乾裂が発生したものが高線量の「黒い土」である.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_9_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"タンデトロン加速器質量分析計業績報告","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18999/sumrua.25.248","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"名古屋大学年代測定資料研究センター","subitem_publisher_language":"ja"}]},"item_9_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"鈴木, 和博","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"84083","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"千葉, 茂樹","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"84084","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"片岡, 達也","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"84085","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"諏訪, 兼位","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"84086","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suzuki, Kazuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"84087","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Chiba, Shigeki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"84088","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kataoka, Tatsuya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"84089","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suwa, Kanenori","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"84090","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":"2018-02-21"}],"displaytype":"detail","filename":"suzuki2013.pdf","filesize":[{"value":"17.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"suzuki2013.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/19830/files/suzuki2013.pdf"},"version_id":"c14bd01c-a2b8-45bc-afe7-11215833ebdb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"黒い土","subitem_subject_scheme":"Other"},{"subitem_subject":"放射性セシウム","subitem_subject_scheme":"Other"},{"subitem_subject":"福島","subitem_subject_scheme":"Other"},{"subitem_subject":"スメクタイト","subitem_subject_scheme":"Other"},{"subitem_subject":"層間陽イオン","subitem_subject_scheme":"Other"},{"subitem_subject":"植物の化学組成","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":"福島県の放射性汚染土壌ーとくに黒い物質ーの鉱物組成と放射性Csの存在状態","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"福島県の放射性汚染土壌ーとくに黒い物質ーの鉱物組成と放射性Csの存在状態","subitem_title_language":"ja"}]},"item_type_id":"9","owner":"1","path":["1728"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-05-13"},"publish_date":"2015-05-13","publish_status":"0","recid":"19830","relation_version_is_last":true,"title":["福島県の放射性汚染土壌ーとくに黒い物質ーの鉱物組成と放射性Csの存在状態"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T04:08:53.711084+00:00"}
