It is not only used as a brachytherapy seed but is also a feasible candidate for Auger electron therapy and gold-nanoparticle therapy. In this study, we propose a new method for the separation of 103Pd from a rhodium target to obtain no-carrier-added 103Pd. Rhodium powder target was irradiated under the following conditions: proton, 50 MeV, 1–3 μA, 1–4 h for the separation study; and H2+, 24 MeV, 5 μA, 1 h to produce 103Pd. The irradiated target was pretreated using an alloying reaction between Rh and Bi on a hotplate at 500 °C. Rhodium in the chemical form of a Bi-Rh compound could then be dissolved with nitric acid and 103Pd was extracted using dimethylglyoxime as an extractant. The target rhodium was recycled using sodium tetrahydroborate (NaBH4). We obtained 103Pd with a yield of 87%. The activity of the product was 26 ± 2 MBq at the end of bombardment (EOB), and the radionuclidic purity of 103Pd was greater than 99%. The decontamination factors of rhodium and bismuth in the 103Pd product were estimated to be greater than 104 and 105, respectively. The target rhodium was recycled with a yield of 91% with a trace of bismuth (9 μg/50 mg Rh). The total separation time for 103Pd was within 3.5 h.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"De Gruyter"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1515/ract-2021-1117","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.degruyter.com/document/doi/10.1515/ract-2021-1117/html","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0033-8230","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":"Tomoyuki, Ohya"}],"nameIdentifiers":[{"nameIdentifier":"1043022","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kotaro, Nagatsu"}],"nameIdentifiers":[{"nameIdentifier":"1043023","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Katsuyuki, Minegishi"}],"nameIdentifiers":[{"nameIdentifier":"1043024","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zhang, Ming-Rong"}],"nameIdentifiers":[{"nameIdentifier":"1043025","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tomoyuki, Ohya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1043026","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kotaro, Nagatsu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1043027","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Katsuyuki, Minegishi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1043028","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zhang, Ming-Rong","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1043029","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":"Separation of 103Pd from a Rh target using an alloying pretreatment with bismuth","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Separation of 103Pd from a Rh target using an alloying pretreatment with bismuth"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-02-17"},"publish_date":"2022-02-17","publish_status":"0","recid":"85195","relation_version_is_last":true,"title":["Separation of 103Pd from a Rh target using an alloying pretreatment with bismuth"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T17:20:39.099942+00:00"}
