The 240Pu/239Pu atom ratios were around 0.18, which indicated the dominant source of global fallout. Consistent sub-surface maximums followed by exponential decline of 239+240Pu activities in the soil cores were observed. Most of the Pu has still remained in the 0-10 cm layers since its deposition. Convection velocities and dispersion coefficients for Pu migration in the soils were estimated by the convection-dispersion equation (CDE) model. The convection velocities and dispersion coefficients ranged from 0.05 to 0.11 cm/y and from 0.06 to 0.29 cm2/y, respectively. Other factors that control the vertical migration of Pu in soil besides precipitation, soil particle size distribution and organic matter were suggested. Long-term migration behaviors of Pu in the soils were simulated. The results provide the Pu background baseline for further environmental monitoring and source identification of non-global fallout Pu inputs in the future.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1016/j.jenvrad.2014.06.010","subitem_relation_type_select":"DOI"}}]},"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":"ト, 文庭"}],"nameIdentifiers":[{"nameIdentifier":"469398","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鄭, 建"}],"nameIdentifiers":[{"nameIdentifier":"469399","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Guo, Qiuju"}],"nameIdentifiers":[{"nameIdentifier":"469400","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内田, 滋夫"}],"nameIdentifiers":[{"nameIdentifier":"469401","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ト 文庭","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"469402","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鄭 建","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"469403","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内田 滋夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"469404","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":"Vertical distribution and migration of global fallout Pu in forest soils in southwestern China","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Vertical distribution and migration of global fallout Pu in forest soils in southwestern China"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-01-20"},"publish_date":"2015-01-20","publish_status":"0","recid":"47018","relation_version_is_last":true,"title":["Vertical distribution and migration of global fallout Pu in forest soils in southwestern China"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:44:53.253537+00:00"}
