Natural geostandard rocks are GSJ geostandard of JG-l. JG-la, JG-2, JR-2 and JR-3, and artificial standard materials of JR-2 with added scheelite powder and tungsten-doped quartz sand were employed for the analysis. Each sample (lOOmg) was irradiated for short time (l min, 2 min and 3 min) at thermal neutron flux 2.8 X 1013 nlcm' Is and for long time (60min) at thermal neutron flux 2.3 X 1013 n I cm2 I s. Gamma-ray spectrum of 187 W at 685.72 keY was used for the tungsten analysis in geostandards. The 187W gamma-ray spectrum was not recognized for Na-rich JG-l (W concentration = 1.5 ppm), while the gamma spectrum of that was recognized for JR-2 (1.8 ppm). SiN ratios of 187W for geostandards that irradiated for 3 min and after cooling for 6 day were higher than those of another irradiation conditions. The analytical error of tungsten in geostandards with the confidential limit of 95% was ± 4.7 ppm. This INAA with 3 min irradiation is the most suitable method for the tungsten-bearing samples was successfully applied to wide range of tungsten (i.e. low W concentration of non-mineralized granites to high W concentration of mineralized granite and scheelite-bearing ore).","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本素材物性学会"}]},"item_10001_version_type_20":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1724099666130":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"09199853","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN10140273","subitem_source_identifier_type":"NCID"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"作成者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"緒方, 武幸","creatorNameLang":"ja"},{"creatorName":"OGATA, Takeyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4518","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"水田, 敏夫","creatorNameLang":"ja"},{"creatorName":"MIZUTA, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4519","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石山, 大三","creatorNameLang":"ja"},{"creatorName":"ISHIYAMA, Daizo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4520","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高田, 實彌","creatorNameLang":"ja"},{"creatorName":"TAKADA, Jitsuya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4521","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-16"}],"displaytype":"detail","filename":"sozai15b1.pdf","filesize":[{"value":"710.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"sozai15b1.pdf","url":"https://air.repo.nii.ac.jp/record/1315/files/sozai15b1.pdf"},"version_id":"4d01bf03-6306-4e93-9f15-5f964e5f95d2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"INAA","subitem_subject_scheme":"Other"},{"subitem_subject":"tungsten","subitem_subject_scheme":"Other"},{"subitem_subject":"gamma-ray spectrum","subitem_subject_scheme":"Other"},{"subitem_subject":"irradiation time","subitem_subject_scheme":"Other"},{"subitem_subject":"granitic rocks","subitem_subject_scheme":"Other"},{"subitem_subject":"scheelite","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"中性子放射化分析法による鉱化および非鉱化の花崗岩中のタングステンの定量","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"中性子放射化分析法による鉱化および非鉱化の花崗岩中のタングステンの定量","subitem_title_language":"ja"},{"subitem_title":"Instrumental Neutron Activation Analysis of Tungsten Content in Mineralized and Non-mineralized Granite","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"15","path":["824"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-10-28"},"publish_date":"2008-10-28","publish_status":"0","recid":"1315","relation_version_is_last":true,"title":["中性子放射化分析法による鉱化および非鉱化の花崗岩中のタングステンの定量"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2024-08-22T06:29:10.290669+00:00"}
