Irradiations were performed with 18 MeV protons at 3 μA for 3 h. The Ac-225 product, purified by the following filtration, radio-colloid formation, reconstitution, and column separation, was obtained in a dried form.\n[Results and Discussion] Production yields of Ac-225 strongly depend on the amount of Ra-226 prepared, where the produced activity of Ac-225 was roughly estimated to be about 1/100 of the Ra-226 activity by the above irradiation condition (9 μAh); e.g., approximately 5 μCi of Ac-225 can be obtained from a 500 μCi of radium target.","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":"第58回日本核医学会学術総会","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":"Nagatsu, Kotaro"}],"nameIdentifiers":[{"nameIdentifier":"658403","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suzuki, Hisashi"}],"nameIdentifiers":[{"nameIdentifier":"658404","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suzuki, Atsushi"}],"nameIdentifiers":[{"nameIdentifier":"658405","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Minegishi, Katsuyuki"}],"nameIdentifiers":[{"nameIdentifier":"658406","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsumoto, Mikio"}],"nameIdentifiers":[{"nameIdentifier":"658407","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shiina, Takuya"}],"nameIdentifiers":[{"nameIdentifier":"658408","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Arai, Kasumi"}],"nameIdentifiers":[{"nameIdentifier":"658409","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Akabori, Shogo"}],"nameIdentifiers":[{"nameIdentifier":"658410","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Higashi, Tatsuya"}],"nameIdentifiers":[{"nameIdentifier":"658411","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zhang, Ming-Rong"}],"nameIdentifiers":[{"nameIdentifier":"658412","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"永津 弘太郎","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"658413","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木 寿","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"658414","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木 篤史","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"658415","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"峯岸 克行","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"658416","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"椎名 卓也","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"658417","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"新井 香純","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"658418","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"赤堀 省吾","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"658419","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"東 達也","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"658420","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"張 明栄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"658421","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":"Feasibility study for the production of Ac-225 from Ra-226 target / ラジウム226を利用したアクチニウム225の製造可能性評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Feasibility study for the production of Ac-225 from Ra-226 target / ラジウム226を利用したアクチニウム225の製造可能性評価"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-11-20"},"publish_date":"2018-11-20","publish_status":"0","recid":"66984","relation_version_is_last":true,"title":["Feasibility study for the production of Ac-225 from Ra-226 target / ラジウム226を利用したアクチニウム225の製造可能性評価"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:42:46.900591+00:00"}
