The mean 239+240Pu and 241Am activity concentrations in the investigated soil cores were 0.278-0.692 mBq/g and 0.128-0.373 mBq/g, respectively, while the accumulative inventories were 63-138.9 Bq/m2 for 239+240Pu and 28.3-61 Bq/m2 for 241Am. The global fallout was thought to be the source of these radionuclides as indicated by the characteristic 241Am/239+240Pu activity ratios and 240Pu/239Pu atomic ratios in these samples. The well-founded convection-dispersion equation (CDE) was used to calculate the migration parameters of 239+240Pu; meanwhile a compartment model was employed to compare the migration of 239+240Pu and 241Am in successive soil layers. This is the first work that comparatively studies the migrations of 239+240Pu and 241Am in Chinese soils in realistic environments. Results showed that the migration behaviors of 239+240Pu and 241Am were rather similar; both velocities were less than 0.3 cm/y in diverse types of soils. These findings were compatible with those of short-term laboratory simulation experiments in China.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"elsevier"}]},"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":"Ni, Youyi"}],"nameIdentifiers":[{"nameIdentifier":"748518","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wang, Zhongtang"}],"nameIdentifiers":[{"nameIdentifier":"748519","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Guo, Qiuju"}],"nameIdentifiers":[{"nameIdentifier":"748520","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zheng, Jian"}],"nameIdentifiers":[{"nameIdentifier":"748521","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Li, Sixuan"}],"nameIdentifiers":[{"nameIdentifier":"748522","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Lin, Jinxian"}],"nameIdentifiers":[{"nameIdentifier":"748523","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tan, Zhaoyi"}],"nameIdentifiers":[{"nameIdentifier":"748524","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Huang, Wenna"}],"nameIdentifiers":[{"nameIdentifier":"748525","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ni, Youyi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"748526","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zheng, Jian","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"748527","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":"Distinctive distributions and migrations of 239+240Pu and 241Am in Chinese forest, grassland and desert soils","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Distinctive distributions and migrations of 239+240Pu and 241Am in Chinese forest, grassland and desert soils"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-05-15"},"publish_date":"2018-05-15","publish_status":"0","recid":"49170","relation_version_is_last":true,"title":["Distinctive distributions and migrations of 239+240Pu and 241Am in Chinese forest, grassland and desert soils"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T01:06:18.148361+00:00"}
