In this work, the determination of uranium in powdered high-purity quartz samples was studied using a simplified fission track procedure in which ∼ 0.5 g each of sample and a fission track detector (synthetic quartz glass plate, uranium impurity ∼ 0.04 ppb) were loaded in a polyethylene capsule and irradiated with a thermal neutron flux of ∼ 1017 cm-2. An easy procedure was also employed for chemical etching of fission tracks. All measurements of uranium concentration in the samples were made on a relative basis by comparing the unknown track densities to that measured for NBS glass SRM 617. The reliability was established for the present determination of uranium down to ∼ 0.1 ppb. The concentrations of uranium in powdered quartz samples studied in this work were in a range from 7.9 down to 0.12 ppb. © 1987 Springer-Verlag.","subitem_description_type":"Abstract"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00010162","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer Verlag"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1007/bf00487232","subitem_relation_type_select":"DOI"}}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0016-1152","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nakanishi, Takashi"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"SC-PR-NAKANISHI-T-491.pdf","filesize":[{"value":"478.1 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-NAKANISHI-T-491.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/10175/files/SC-PR-NAKANISHI-T-491.pdf"},"version_id":"0d338612-b3e8-4772-8064-cad43493e893"}]},"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":"Determination of uranium in powdered quartz at ppb level by fission track method","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Determination of uranium in powdered quartz at ppb level by fission track method"}]},"item_type_id":"4","owner":"3","path":["937"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"10175","relation_version_is_last":true,"title":["Determination of uranium in powdered quartz at ppb level by fission track method"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T10:56:11.536517+00:00"}
