The audit was performed for the reference condition of linac X-ray beams, which was a 10x10 cm2 field and a 10cm depth with a SSD of 90 cm. Eight facilities from 5 countries, China, Korea, Indonesia, Viet Nam and the Philippines, participated in this audit. The ratios of deviation between the user-stated dose and the NIRS measured dose were analyzed. Among 24 X-rays beams measured from 6 to 20MV, 22 beams were within optimum levels (3%) and 1 beam was out of the optimum level but within the tolerance level (5%). However, 1 beam exceeded the tolerance level. The standard deviation of the ratios of deviation was 1.4%. A thorough and lengthy investigation was performed regarding this beam, which was observed to have a large rate of deviation (+6.1%). Finally, the cause became clear when it was deter-mined that an incorrect pressure value in the calibration of a monitoring unit had been used. This event shows the impor-tance of external audit in radiation therapy.","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":"WORLD CONGRESS 2009","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":"Mizuno, Hideyuki"}],"nameIdentifiers":[{"nameIdentifier":"685768","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"et.al"}],"nameIdentifiers":[{"nameIdentifier":"685769","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"水野 秀之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"685770","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":"Dose audit using a glass dosimeter for Radiation Therapy Facilities in East-Asian Countries","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Dose audit using a glass dosimeter for Radiation Therapy Facilities in East-Asian Countries"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-09-15"},"publish_date":"2009-09-15","publish_status":"0","recid":"69849","relation_version_is_last":true,"title":["Dose audit using a glass dosimeter for Radiation Therapy Facilities in East-Asian Countries"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:09:43.661474+00:00"}
