Then, a 60Co gamma-ray standard field for therapy-level dosimeter calibration in terms of absorbed dose to water was developed at National Institute of Radiological Sciences (NIRS) as a secondary standard dosimetry laboratory (SSDL). The results of an IAEA/WHO TLD SSDL audit demonstrated that there was good agreement between NIRS stated absorbed dose to water and IAEA measurements. The IAEA guide based on the ISO standard was used to estimate the relative expanded uncertainty of the calibration factor for a therapy level Farmer-type ionization chamber in terms of absorbed dose to water (ND,w) with the new field. The uncertainty of ND,w was estimated to be 1.1 % (k=2), which corresponds to approximately one third of the value determined in the existing air kerma field. The dissemination of traceability of the calibration factor determined in the new field is expected to diminish the uncertainty of dose delivered to patients significantly.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本医学物理学会"}]},"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":"福村, 明史"}],"nameIdentifiers":[{"nameIdentifier":"468165","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"水野, 秀之"}],"nameIdentifiers":[{"nameIdentifier":"468166","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"深堀, 麻衣"}],"nameIdentifiers":[{"nameIdentifier":"468167","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐方, 周防"}],"nameIdentifiers":[{"nameIdentifier":"468168","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"福村 明史","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"468169","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"水野 秀之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"468170","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"深堀 麻衣","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"468171","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐方 周防","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"468172","nameIdentifierScheme":"WEKO"}]}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"放射線治療用水吸収線量校正場の開発と水吸収線量校正定数の不確かさ","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"放射線治療用水吸収線量校正場の開発と水吸収線量校正定数の不確かさ"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-11-10"},"publish_date":"2014-11-10","publish_status":"0","recid":"46914","relation_version_is_last":true,"title":["放射線治療用水吸収線量校正場の開発と水吸収線量校正定数の不確かさ"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:46:06.646763+00:00"}
