We present the historical record of atmospheric Pu fallout reconstructed from a sediment core from Lake Hongfeng, China.  The Pu activity profile was in agreement with the 137Cs profile. Inventories were 50.7 Bq m-2 for 239+240Pu and 1586 Bq m-2 for 137Cs. The average 240Pu/239Pu atom ratio was 0.185  0.009, indicating that Pu originated from global stratospheric fallout rather than from direct tropospheric or close-in fallout from the Chinese nuclear testing conducted in the 1970s. Our data suggested that Lake Hongfeng would be an ideal setting for monitoring atmospheric fallout and environmental changes in this region.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0269-7491","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":"447868","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wu, Fengchang"}],"nameIdentifiers":[{"nameIdentifier":"447869","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamada, Masatoshi"}],"nameIdentifiers":[{"nameIdentifier":"447870","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Liao, Haiqing"}],"nameIdentifiers":[{"nameIdentifier":"447871","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Liu, Chongqiang"}],"nameIdentifiers":[{"nameIdentifier":"447872","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wan, Guojiang"}],"nameIdentifiers":[{"nameIdentifier":"447873","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鄭 建","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"447874","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ｗｕ Ｆｅｎｇｃｈａｎｇ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"447875","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山田 正俊","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"447876","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ｌｉａｏ Ｈａｉｑｉｎｇ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"447877","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":"Global fallout Pu recorded in lacustrine sediments in Lake Hongfeng, SW China","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Global fallout Pu recorded in lacustrine sediments in Lake Hongfeng, SW China"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-03-03"},"publish_date":"2008-03-03","publish_status":"0","recid":"45101","relation_version_is_last":true,"title":["Global fallout Pu recorded in lacustrine sediments in Lake Hongfeng, SW China"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:07:41.214369+00:00"}
