The emission rate of radon emanated from the disk depended on the content of 226Ra and the sintering temperature. A 226Ra sulfate (226RaSO4) solution was dropped on a fibrous SiC ceramic disk (33 mmφ) of 1 mm in thickness, and sintered at 400 ◦C. The radon concentration from a disk containing 226Ra of 1.85 MBq was measured to be 38 kBq m−3 at a carrier airflow rate of 0.5 L min−1. By adjusting the 226Ra content or the sweep airflow rate, the radon concentrations were easily controlled over a wide range of over three orders of magnitude. The concentration was very stable for a long term. The compactness of the source disk made is easy for handling the source container and the shielding of\ngamma radiation from 226Ra and its decay products. Such advantages in a radon generation system are desirable for experiments of high-level, large-scale radon exposure.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"AIP Publishing"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1063/1.4847155","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://dx.doi.org/10.1063/1.4847155"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1063/1.4847155","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0034-6748","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":"Fukutsu, Kumiko"}],"nameIdentifiers":[{"nameIdentifier":"466223","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamada, Yuji"}],"nameIdentifiers":[{"nameIdentifier":"466224","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"福津 久美子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"466225","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山田 裕司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"466226","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":"Development of  radon sources with a high stability and a wide range","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of  radon sources with a high stability and a wide range"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-05-08"},"publish_date":"2014-05-08","publish_status":"0","recid":"46750","relation_version_is_last":true,"title":["Development of  radon sources with a high stability and a wide range"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:48:03.415362+00:00"}
