The α spectrometric method for sensitive analysis of ^<210>Pb in ice samples and the method of ice core dating are described in this paper. Measurements of ^<210>Pb in ice cores from the Arctic glacier, Åsgardfonna, in the Svalbard archipelagos have been made. The activity of ^<210>Pb was obtained by counting α rays from its daughter nuclide, ^<210>Po (half-life 138 days). The specific activity of ^<210>Pb at the surface of the glacier, 110mBq/kg, decreased exponentially with depth to 4.72mBq/kg at about 30m depth. Below 30m, the activities were nearly constant and its average value from 30m to 180m was 4.85±1.33mBq/kg. The results indicate that the atmospheric ^<210>Pb deposit onto a glacier decays as a function of time at a rate controlled by its half-life.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00008945","subitem_identifier_reg_type":"JaLC"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00181831","subitem_source_identifier_type":"NCID"}]},"item_1_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00857289","subitem_source_identifier_type":"ISSN"}]},"item_1_subject_21":{"attribute_name":"国際十進分類法","attribute_value_mlt":[{"subitem_subject":"551.32","subitem_subject_scheme":"UDC"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Graduate School of Science, Yamagata University"},{"subitem_text_language":"en","subitem_text_value":"Graduate School of Science, Yamagata University"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"山形大学大学院理学研究科"},{"subitem_text_value":"山形大学大学院理学研究科"},{"subitem_text_value":"国立極地研究所"},{"subitem_text_value":"国立極地研究所"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1996-11-01"}],"displaytype":"detail","filename":"KJ00000140281.pdf","filesize":[{"value":"362.8 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000140281","url":"https://nipr.repo.nii.ac.jp/record/8945/files/KJ00000140281.pdf"},"version_id":"cbe43084-59c1-41d9-a58e-f4de174a10f4"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"雪氷試料の化学解析-アルファ線波高分析法を用いた雪氷中 210Pb の高感度測定-","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"雪氷試料の化学解析-アルファ線波高分析法を用いた雪氷中 210Pb の高感度測定-"},{"subitem_title":"Chemical analysis of snow and ice samples-High sensitive measurement of 210Pb in snow and ice samples by using alpha spectrometry-","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["1115"],"pubdate":{"attribute_name":"公開日","attribute_value":"1996-11-01"},"publish_date":"1996-11-01","publish_status":"0","recid":"8945","relation_version_is_last":true,"title":["雪氷試料の化学解析-アルファ線波高分析法を用いた雪氷中 210Pb の高感度測定-"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:12:43.179146+00:00"}
