The radiation doses of crew are estimated using a recently developed program for calculation of aviation route doses JISCARD EX which has employed a PHITS-based analytical model PARMA.  For reliable assessments, precision of calculated doses are desirably to be verified by measurements at high altitude..\nWe thus measured cosmic radiation at the summit of Mt. Fuji (3,776m in altitude), the highest mountain in Japan, for comparison of dose rates with model calculations.  Measurements during the summer from July to August were carried out repeatedly three times on 2007, 2008 and 2009 in a building of the Mt.Fuji weather station using selected radiation monitors such as several types of neutron monitor, phoswich scintillation detectors and an ionizing chamber coupled each with an exclusive data logger.\nAs results, ambient dose equivalent rates measured for the solar minimum agreed well with model calculations.  Possible systematic errors attributing to the uncertain spectra of high-energy cosmic-ray components are discussed according to separated signals of the scintillation detector.","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":"11th Neutron and Ion Dosimetry Symposium (NEUDOS-11）","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":"Yasuda, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"686277","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yajima, Kazuaki"}],"nameIdentifiers":[{"nameIdentifier":"686278","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"保田 浩志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"686279","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"矢島 千秋","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"686280","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":"Verification of cosmic radiation dose rates at the summit of Mt.Fuji","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Verification of cosmic radiation dose rates at the summit of Mt.Fuji"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-10-19"},"publish_date":"2009-10-19","publish_status":"0","recid":"69899","relation_version_is_last":true,"title":["Verification of cosmic radiation dose rates at the summit of Mt.Fuji"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:09:09.235794+00:00"}
