Civil and military aircraft currently on the drawing board are expected to fly at higher altitudes (12 km) and possess longer ranges than do existing aircraft, exposing their crews to higher levels of ionizing radiation for longer periods of time. We are currently carrying out measurements of the ionizing radiation environment at 20 km altitude using portable Si detectors aboard NASAs two ER2 high altitude research aircraft. The instruments (Liulin 4J) were produced by Solar Terrestrial Influences Laboratory, Bulgaria and have been extensively calibrated at several particle accelerators. With these instruments, we can measure not only total absorbed dose but also variation of the absorbed dose as a function of time. We report radiation dose measurements as functions of time, altitude, magnetic latitude and, solar activity.","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":"34th Scientific Assembly","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":"Uchihori, Yukio"}],"nameIdentifiers":[{"nameIdentifier":"592358","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Benton, Eric"}],"nameIdentifiers":[{"nameIdentifier":"592359","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Moeller, James"}],"nameIdentifiers":[{"nameIdentifier":"592360","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内堀 幸夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"592361","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":"RADIATION MEASUREMENTS ABOARD NASAS ER2 HIGH ALTITUDE AIRCRAFT WITH THE LIULIN 4J PORTABLE SPECTROMETER","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"RADIATION MEASUREMENTS ABOARD NASAS ER2 HIGH ALTITUDE AIRCRAFT WITH THE LIULIN 4J PORTABLE SPECTROMETER"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2002-12-25"},"publish_date":"2002-12-25","publish_status":"0","recid":"59507","relation_version_is_last":true,"title":["RADIATION MEASUREMENTS ABOARD NASAS ER2 HIGH ALTITUDE AIRCRAFT WITH THE LIULIN 4J PORTABLE SPECTROMETER"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T22:04:09.248452+00:00"}
