A theoretical model was established to calculate the EEC with optimization. Subsequently, an exposure experiment was carried out to test the performance of this detector, and we compared the chamber experiment and the theoretical model by estimating and measuring various parameters. The deposition flux of progeny derived from the prediction agreed well with the value measured in the exposure chamber. The energy-weighted net track density (NTD) measured by this detector is much more reliable to reflect the linear relation between NTD and time-integrated EEC. Since the detector is sensitive to the exposure environmental condition, it is recommended to apply the detector to measure the EEC after its calibration in a typical indoor environment.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.3390/ijerph17228569","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.mdpi.com/1660-4601/17/22/8569","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1660-4601","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hu, Jun"}],"nameIdentifiers":[{"nameIdentifier":"1013824","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Guosheng Yang"}],"nameIdentifiers":[{"nameIdentifier":"1013825","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kranrod, Chutima"}],"nameIdentifiers":[{"nameIdentifier":"1013826","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iwaoka, Kazuki"}],"nameIdentifiers":[{"nameIdentifier":"1013827","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hosoda, Masahiro"}],"nameIdentifiers":[{"nameIdentifier":"1013828","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tokonami, Shinji"}],"nameIdentifiers":[{"nameIdentifier":"1013829","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yang, Guosheng","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1013830","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kazuki, Iwaoka","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1013831","nameIdentifierScheme":"WEKO"}]}]},"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":"An Improved Passive CR-39-Based Direct 222Rn/220Rn","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"An Improved Passive CR-39-Based Direct 222Rn/220Rn"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-11-20"},"publish_date":"2020-11-20","publish_status":"0","recid":"81069","relation_version_is_last":true,"title":["An Improved Passive CR-39-Based Direct 222Rn/220Rn"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:50:53.530128+00:00"}
