Detailed results of Pu activity and isotope composition will be reported. With a mean chemical yield of 65 % for 242Pu tracer, we found that the experimentally established values for 239Pu, 240Pu, 241Pu and 239+240Pu activities are almost the same as those in the IAEA-381 seawater reference material. Regarding the 239+240Pu activity, we provided the most precise and accurate result among the twelve laboratories participated in the interlaboratory comparison.","subitem_description_type":"Abstract"}]},"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":"Zheng, Jian"}],"nameIdentifiers":[{"nameIdentifier":"554661","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamada, Masatoshi"}],"nameIdentifiers":[{"nameIdentifier":"554662","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鄭 建","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"554663","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山田 正俊","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"554664","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 paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Precise determination of Pu isotopes in a newly certified seawater reference material IAEA-443 using isotope-dilution SF-ICP-MS","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Precise determination of Pu isotopes in a newly certified seawater reference material IAEA-443 using isotope-dilution SF-ICP-MS"}]},"item_type_id":"10003","owner":"1","path":["2"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-11-24"},"publish_date":"2011-11-24","publish_status":"0","recid":"54303","relation_version_is_last":true,"title":["Precise determination of Pu isotopes in a newly certified seawater reference material IAEA-443 using isotope-dilution SF-ICP-MS"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:02:31.951493+00:00"}
