Since Japanese non-agricultural fields has an average U/Th ratio of 0.23, thus, using U/Th ratios in non-agricultural areas, we thought that it is possible to calculate amounts of excess U due to the application of fertilizers. It was estimated that about 50% of total U in paddy field soils (range: 4-78%) and about 48% of total U in upland field soils (range: 4-74%) were originated from the phosphatic fertilizers.","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 32th Waste Management Symposium (WM'06)","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":"670679","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Uchida, Shigeo"}],"nameIdentifiers":[{"nameIdentifier":"670680","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takeda, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"670681","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田上 恵子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"670682","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内田 滋夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"670683","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"武田 洋","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"670684","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":"Estimation of anthropogenic uranium concentration in Japanese agricultural soils from phosphatic fertilizers","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Estimation of anthropogenic uranium concentration in Japanese agricultural soils from phosphatic fertilizers"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-03-06"},"publish_date":"2006-03-06","publish_status":"0","recid":"68317","relation_version_is_last":true,"title":["Estimation of anthropogenic uranium concentration in Japanese agricultural soils from phosphatic fertilizers"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:27:32.602319+00:00"}
