Finally, the permeability (diffusion coefficient) of the investigated membrane is derived using one-dimensional stationary radon diffusion described by the differential equation.\nMoreover, due to relatively large volumes of both containers (source and receiver) the investigation of diffusion process in relation to changeability of environmental parameters (humidity and temperature) is also possible.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"7th International Conference on Protection Against Radon at Home and at Work","subitem_description_type":"Other"}]},"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":"Miroslaw, JANIK"}],"nameIdentifiers":[{"nameIdentifier":"700301","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ishikawa, Tetsuo"}],"nameIdentifiers":[{"nameIdentifier":"700302","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yonehara, Hidenori"}],"nameIdentifiers":[{"nameIdentifier":"700303","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ミロソラフ ヤニック","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"700304","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石川 徹夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"700305","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"米原 英典","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"700306","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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"RADIF- NIRS System for Measurement of Radon Diffusion in Membranes","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"RADIF- NIRS System for Measurement of Radon Diffusion in Membranes"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-09-17"},"publish_date":"2013-09-17","publish_status":"0","recid":"71241","relation_version_is_last":true,"title":["RADIF- NIRS System for Measurement of Radon Diffusion in Membranes"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:53:32.308360+00:00"}
