It was found that the background count rate was proportional to ambient dose equivalent rate and the detection limit for the monitor at 20 μSv h^<−1> as an ambient dose equivalent rate was evaluated to be 187 Bq m^<−3> using the ISO11929 method. These results suggest that the detection limit for the system can be decreased effectively by lead shielding with optimized thickness.","subitem_description_type":"Other"},{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_30002_file35":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"1-s2.0-S2213020919300217-main.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2011206/files/1-s2.0-S2213020919300217-main.pdf"},"version_id":"bf31bdb0-7901-4013-b84b-b1e13845e136"}]},"item_30002_identifier16":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/47105"}]},"item_30002_language12":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_30002_publisher10":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"Elsevier","subitem_publisher_language":"en"}]},"item_30002_relation18":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.pisc.2019.100414","subitem_relation_type_select":"DOI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.pisc.2019.100414","subitem_relation_type_select":"DOI"}}]},"item_30002_resource_type13":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_30002_rights6":{"attribute_name":"Rights","attribute_value_mlt":[{"subitem_rights":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0","subitem_rights_language":"en"},{"subitem_rights":"http://creativecommons.org/licenses/by-nc-nd/4.0/","subitem_rights_language":"en","subitem_rights_resource":"http://creativecommons.org/licenses/by-nc-nd/4.0/"}]},"item_30002_source_identifier22":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"2213-0209","subitem_source_identifier_type":"ISSN"}]},"item_30002_source_title23":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_source_title":"Perspectives in Science","subitem_source_title_language":"en"}]},"item_30002_subject8":{"attribute_name":"Subject","attribute_value_mlt":[{"subitem_subject":"Radioactive plume","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Continuous air sampling","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Silicon photodiode","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Detection limit","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_30002_title0":{"attribute_name":"Title","attribute_value_mlt":[{"subitem_title":"A portable radioactive plume monitor using a silicon photodiode","subitem_title_language":"en"}]},"item_30002_version_type15":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_title":"A portable radioactive plume monitor using a silicon photodiode","item_type_id":"30002","owner":"1","path":["1642838338003","1642838406414"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-10-28"},"publish_date":"2020-10-28","publish_status":"0","recid":"2011206","relation_version_is_last":true,"title":["A portable radioactive plume monitor using a silicon photodiode"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2025-02-18T11:27:25.505174+00:00"}
