Since these products are contained in the scintillator as internal radiation sources, the radioactivity can be measured with extremely high detection efficiency. In addition, since a large amount of radioactivity can be obtained with a short irradiation time, measurement with high sensitivity is possible. In this study, we developed a simple method to measure thermal neutron flux without using the cadmium filter method by utilizing the fact that two kinds of nuclides (Cs-134m and I-128) are produced in the scintillator by a single short time neutron irradiation.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究(C); 研究期間：2018～2021; 課題番号：18K04996; 研究分野：放射線工学; 科研費の分化・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ(WEKO2)","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Wakabayashi, Genichiro"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学原子力研究所; 教授"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"若林, 源一郎"},{"creatorName":"ワカバヤシ, ゲンイチロウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-12-05"}],"displaytype":"detail","filename":"18K04996seika.pdf","filesize":[{"value":"200.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"18K04996seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/23368/files/18K04996seika.pdf"},"version_id":"858e99d7-4771-46ec-850f-3d6008959494"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"シンチレータ","subitem_subject_scheme":"Other"},{"subitem_subject":"自己放射化","subitem_subject_scheme":"Other"},{"subitem_subject":"熱中性子束","subitem_subject_scheme":"Other"},{"subitem_subject":"ヨウ化セシウム","subitem_subject_scheme":"Other"},{"subitem_subject":"カドミウムフィルタ法","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"シンチレータの放射化を利用した放射線治療場中性子測定システムの開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"シンチレータの放射化を利用した放射線治療場中性子測定システムの開発","subitem_title_language":"ja"},{"subitem_title":"Development of Neutron Measurement System for Radiation Therapy Field Using the Activation of a Scintillator","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4819"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-12-05"},"publish_date":"2022-12-05","publish_status":"0","recid":"23368","relation_version_is_last":true,"title":["シンチレータの放射化を利用した放射線治療場中性子測定システムの開発"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-09-12T05:15:08.263991+00:00"}
