Purpose of this study is to investigate the variation in absorbed dose to water calibration coefficients among chambers of the same type.\nResults: For shallow type chambers, PTW 34001 is the least variable (1.2% standard deviation. IBA NACP-02 and PTW 23343 chamber exhibit the most variation (3.9% and 4.3% standard deviation) respectively. For almost all types of cylindrical chambers, variations of coefficients are less than those of shallow type chambers. And it is showed that both for cylindrical chamber and for shallow chamber, the smaller collecting volume leads to the more variation of coefficients.\nConclusion: Absorbed dose to water calibration coefficient by types of ionization chamber were collected by ANTM. It is found that a tendency of coefficients distribution is different for each chamber type, and small chamber volume leads to more variable of coefficients.","subitem_description_type":"Abstract"}]},"item_10003_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"株式会社国際文献社（一般社団法人日本医学物理学会）"}]},"item_10003_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1345-5362","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":"Yamasita, Wataru"}],"nameIdentifiers":[{"nameIdentifier":"561112","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakata, Suoh"}],"nameIdentifiers":[{"nameIdentifier":"561113","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takase, Nobuhiro"}],"nameIdentifiers":[{"nameIdentifier":"561114","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hoteida, Masahiro"}],"nameIdentifiers":[{"nameIdentifier":"561115","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Okuyama, Hiroaki"}],"nameIdentifiers":[{"nameIdentifier":"561116","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Narita, Katsuhisa"}],"nameIdentifiers":[{"nameIdentifier":"561117","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Endo, Masahiro"}],"nameIdentifiers":[{"nameIdentifier":"561118","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mizuno, Hideyuki"}],"nameIdentifiers":[{"nameIdentifier":"561119","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukumura, Akifumi"}],"nameIdentifiers":[{"nameIdentifier":"561120","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐方 周防","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"561121","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"水野 秀之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"561122","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"福村 明史","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"561123","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 paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Absorbed dose to water calibration coefficient by types of ionization chambers","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Absorbed dose to water calibration coefficient by types of ionization chambers"}]},"item_type_id":"10003","owner":"1","path":["2"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-03-22"},"publish_date":"2018-03-22","publish_status":"0","recid":"54872","relation_version_is_last":true,"title":["Absorbed dose to water calibration coefficient by types of ionization chambers"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T22:55:49.144899+00:00"}
