The control system uses digital PID \n(Proportional, Integral, Derivative) control methods based on a LabVIEW program1). It was possible to attain \nstable conditions in a shorter time by this system. The standard deviation of the measurements using the \ncalorimeter was 0.79 % at a dose rate of 0.8 Gy/min in seventeen calorimeter runs of a 60Co photon beam. The \noverall uncertainty for the absorbed dose to graphite and water of a 60Co photon beam using the developed \ncalorimeter was 0.89 % and 1.35 %, respectively. Estimations of the correction factors due to vacuum gaps, \nimpurities in the core, the dose gradient and the radiation profile were included in the uncertainty. The \nabsorbed doses to graphite and water irradiated by a 60Co photon beam were compared with dosimetry using \nionization chambers. The absorbed doses to graphite and water estimated by the two dosimetry methods agreed \nwithin 0.1 % and 0.3 %, respectively.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1345-5354","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":"Sakama, Makoto"}],"nameIdentifiers":[{"nameIdentifier":"449146","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kanai, Tatsuaki"}],"nameIdentifiers":[{"nameIdentifier":"449147","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukumura, Akifumi"}],"nameIdentifiers":[{"nameIdentifier":"449148","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"坂間 誠","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"449149","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"金井 達明","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"449150","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"福村 明史","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"449151","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 a Portable Graphite Calorimeter for Radiation Dosimetry","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of a Portable Graphite Calorimeter for Radiation Dosimetry"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-07-08"},"publish_date":"2008-07-08","publish_status":"0","recid":"45220","relation_version_is_last":true,"title":["Development of a Portable Graphite Calorimeter for Radiation Dosimetry"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:06:19.030266+00:00"}
