In this study, U concentrations in rice and associated soil samples have been determined by inductively coupled plasma mass spectrometry (ICP-MS) after chemical separation with TRU resin (Eichrom). After U extraction on the resin by sample solution loading, tetramethyl ammonium hydroxide was studied for U elution behavior from the resin cartridges. Chemical recovery with this method was about 85%. Then U concentrations in three kinds of rice grain samples, brown rice (hulled rice), white rice (polished rice) and bran (63 samples each), were measured by ICP-MS after the TRU resin extraction method. U concentrations in all samples were measured and the geometric means in white rice, brown rice and bran samples were 7.3 x 10-5, 9.7 x 10-5 and 3.7 x 10-4 mg/kg-dry, respectively. TFs for white rice ranged from 6.2 x 10-6 to 7.9 x 10-5 with a geometric means of 2.7 x 10-5, whereas those for brown rice ranged from 5.5 x 10-6 to 4.6 x 10-4 with a geometric means of 3.6 x 10-5. These values were 2 orders of magnitude lower than the TF for cereals of 1.3 x 10-3 proposed by IAEA.","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":"Waste Management Symposia 2009","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":"Tagami, Keiko"}],"nameIdentifiers":[{"nameIdentifier":"684156","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Uchida, Shigeo"}],"nameIdentifiers":[{"nameIdentifier":"684157","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hirai, Ikuko"}],"nameIdentifiers":[{"nameIdentifier":"684158","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田上 恵子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"684159","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内田 滋夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"684160","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"平井 育子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"684161","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":"Soil-to-plant transfer factor of uranium by measuring naturally occurring uranium at trace levels in plants and soils by ICP-MS","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Soil-to-plant transfer factor of uranium by measuring naturally occurring uranium at trace levels in plants and soils by ICP-MS"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-03-09"},"publish_date":"2009-03-09","publish_status":"0","recid":"69699","relation_version_is_last":true,"title":["Soil-to-plant transfer factor of uranium by measuring naturally occurring uranium at trace levels in plants and soils by ICP-MS"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:11:26.847597+00:00"}
