This nuclide is one of the most important radionuclides for dose assessment because of its\nhigh mobility in soil and availability to plants. The most stable chemical form under natural\nsurface water conditions is TcO4 - , which is highly soluble and rarely adsorbed onto soil\nparticle surfaces. The chemical form of Tc, however, changes with environmental conditions.\nThus it is necessary, for realistic assessment, to obtain transfer parameters, such as soil-to-plant\ntransfer factors (TFs), under natural conditions, but the data have been limited due to\ntrace levels of 99 Tc. Obtaining TFs using global fallout 99 Tc in fields is difficult, because the\nconcentration of 99 Tc is very low. Therefore, we focused on the Chernobyl site where 99 Tc\nconcentration levels have already been shown to be higher than those from global fallout Tc\n(Uchida et al., 1999).\nIn this study, we determined the concentrations of 99 Tc in soils and plant leaves collected near\nthe Chernobyl site to investigate the transfer of the nuclide in soil-plant systems under natural\nconditions.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"International Conference on Radioactivity in the Environment","subitem_description_type":"Other"}]},"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":"Uchida, Shigeo"}],"nameIdentifiers":[{"nameIdentifier":"671229","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tagami, Keiko"}],"nameIdentifiers":[{"nameIdentifier":"671230","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ruhm, Werner"}],"nameIdentifiers":[{"nameIdentifier":"671231","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Steiner, M."}],"nameIdentifiers":[{"nameIdentifier":"671232","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wirth, Erich"}],"nameIdentifiers":[{"nameIdentifier":"671233","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内田 滋夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"671234","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田上 恵子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"671235","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 object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Measurement of Chernobyl fallout technetium-99 in plant samples and its transfer in soil-plant systems","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Measurement of Chernobyl fallout technetium-99 in plant samples and its transfer in soil-plant systems"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-06-05"},"publish_date":"2006-06-05","publish_status":"0","recid":"68370","relation_version_is_last":true,"title":["Measurement of Chernobyl fallout technetium-99 in plant samples and its transfer in soil-plant systems"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:26:54.608145+00:00"}
