Sc and REE were simultaneously determined using radiochemical neutron activation method. This method is sensitive enough for detection of as little as lower than 10^<-13>gSc/g, compared to the level of cosmic ray effects in irons which are usually in the range of 10^<-9>-10^<-12>gSc/g. The lowest concentration found in irons was 2×10^<-12>gSc/g in the Campo del Cielo and similar contents were observed in the Gibeon, DRP-78008 (and Brenham-metal). Even at these low levels, Sc seems mostly attributable to cosmic ray production. The Sc content in irons is best compared with cosmogenic ^4He. The ratio of Sc to ^4He, approximately 1×10^<-12>gSc/1×10^<-8>cc ^4He, or an average atomic ratio of 1 : 19±3,was observed independent of shielding. Technical aspects of metal phase separation from ordinary chondrites were studied. In one Peace River metal sample, 0.9 ppbSc was found. This number corresponds to 0.01% of the stone phase in the metal. This level of contamination seems still higher than the cosmogenic level of 0.2 ppbSc expected in the metal phase of this meteorite.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004456","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA10784627","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"College of Humanities and Sciences, Nihon University/College of Humanities and Sciences, Nihon University/Department of Earth Sciences, Faculty of Science, Yamagata University/College of Humanities and Sciences, Nihon University/College of Humanities and Sciences, Nihon University/College of Humanities and Sciences, Nihon University/College of Humanities and Sciences, Nihon University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1988-03-01"}],"displaytype":"detail","filename":"KJ00000036262.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000036262","url":"https://nipr.repo.nii.ac.jp/record/4456/files/KJ00000036262.pdf"},"version_id":"716328f8-a8ec-449f-b63d-501787983f4f"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Scandium 45 in meteoritic irons","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Scandium 45 in meteoritic irons"}]},"item_type_id":"1","owner":"4","path":["585"],"pubdate":{"attribute_name":"公開日","attribute_value":"1988-03-01"},"publish_date":"1988-03-01","publish_status":"0","recid":"4456","relation_version_is_last":true,"title":["Scandium 45 in meteoritic irons"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:20:24.756725+00:00"}
