The ^<26>(Al) activities range from 72 to 29 dpm/kg. If we assume that the saturation activity of ^<26>(Al) in chondrites is 60,about 1/3 of the measured meteorites show the contents close to this value; however, the rest show lower values. A simple graphical method was applied to estimate the exposure and terrestrial ages based on ^<26>(Al) and ^<53>(Mn) data, and these ages are compared with exposure ages obtained by ^<21>(Ne) measurements. The results are generally consistent with the ^<21>(Ne) data. It must be noted that the Antarctic meteorites are highly contaminated with fallout ^<137>(Cs) derived from nuclear test explosions.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","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":"Low Level Radioactivity Lavoratory, Kanazawa University"},{"subitem_text_language":"en","subitem_text_value":"Low Level Radioactivity Lavoratory, Kanazawa University"},{"subitem_text_language":"en","subitem_text_value":"Low Level Radioactivity Lavoratory, Kanazawa University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1982-12-01"}],"displaytype":"detail","filename":"KJ00000012023.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012023","url":"https://nipr.repo.nii.ac.jp/record/1389/files/KJ00000012023.pdf"},"version_id":"03dc9a50-916e-4b8a-b4bb-04fabdf628bb"}]},"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":"Non-destructive measurements of cosmogenic 26Al, natural 40K and fallout 137Cs in Antarctic meteorites","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Non-destructive measurements of cosmogenic 26Al, natural 40K and fallout 137Cs in Antarctic meteorites","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["379"],"pubdate":{"attribute_name":"公開日","attribute_value":"1982-12-01"},"publish_date":"1982-12-01","publish_status":"0","recid":"1389","relation_version_is_last":true,"title":["Non-destructive measurements of cosmogenic 26Al, natural 40K and fallout 137Cs in Antarctic meteorites"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:51:06.109511+00:00"}
