With a mean chemical yield of 65 % determined with 242Pu as a tracer, we found that the experimentally established values in IAEA-443 for 239Pu, 240Pu, 241Pu and 239+240Pu activities are almost the same as those in IAEA-381. Regarding the 239+240Pu activity, we provided the most precise and accurate result among the twelve laboratories which participated in the interlaboratory comparison. In addition, for the 240Pu/239Pu atom ratio, our results for IAEA-381 (0.2315 +/- 0.0008) and IAEA-443 (0.2325 +/- 0.0008) are in good agreement with the IAEA information value (0.229 +/- 0.006), but have much smaller uncertainty. Since the new seawater reference material, IAEA-443, is commercially available, it can be used not only for method validation for seawater plutonium isotope ratio and activity analysis, but also for more general use as a plutonium isotope standard for mass discrimination correction for other environmental samples.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0969-8043","subitem_source_identifier_type":"ISSN"}]},"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":"461856","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamada, Masatoshi"}],"nameIdentifiers":[{"nameIdentifier":"461857","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鄭 建","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"461858","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山田 正俊","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"461859","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Determination of plutonium isotopes in seawater reference materials using isotope-dilution ICP-MS","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Determination of plutonium isotopes in seawater reference materials using isotope-dilution ICP-MS"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-07-20"},"publish_date":"2012-07-20","publish_status":"0","recid":"46365","relation_version_is_last":true,"title":["Determination of plutonium isotopes in seawater reference materials using isotope-dilution ICP-MS"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:52:42.455883+00:00"}
