Environ. Radioact. 141, 8-13, 2015). It is important to compare these values observed after the Fukushima and Chernobyl accidents to understand the difference/similarity of radiocesium fate in the environments and radiation effects to human and biota from these accidents. Therefore, we did literature survey and field observation to compare Teff in trees.\n     In order to reduce the climate effect, we selected 137Cs data in Japanese black pine and tea tree leaves, and Citrus unshiu fruits collected in Japan from 1985 to 2013 using the environmental radiation database (Nuclear Regulation Authority, http://search.kankyo-hoshano.go.jp/servlet/search.top, in Japanese, 2016). From the database, we found direct deposition effect from the Chernobyl accident (1986-1988) and the Fukushima accident (2011-2013). We also measured 137Cs concentrations in Citrus natsudaidai for comparison from September 2011 to March 2014 at our institute campus in Chiba City, Japan.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"The 2nd international conference on radioecological concentration processes","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Tagami, Keiko"}],"nameIdentifiers":[{"nameIdentifier":"709704","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Uchida, Shigeo"}],"nameIdentifiers":[{"nameIdentifier":"709705","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ishii, Nobuyoshi"}],"nameIdentifiers":[{"nameIdentifier":"709706","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田上 恵子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"709707","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内田 滋夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"709708","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石井 伸昌","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"709709","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Effective half-lives of radiocesium in different Japanese tree species","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effective half-lives of radiocesium in different Japanese tree species"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-11-17"},"publish_date":"2016-11-17","publish_status":"0","recid":"72059","relation_version_is_last":true,"title":["Effective half-lives of radiocesium in different Japanese tree species"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:44:17.998947+00:00"}
