The dosimetric quantities are constantly changing and depend mainly on the level of solar activity and the various spacecraft- and orbit-dependent parameters such as the shielding distribution surrounding the detectors, location of the spacecraft within its orbit relative to the Earth, the attitude (orientation) and altitude. Consequently, continuous monitoring of dosimetric quantities is required to record and evaluate the personal radiation dose for crew members during spaceflight. The constant dose measurement through long-term duration at a fixed location would give a crucial data related with the changes of solar activity and other parameters.\nWe have measured the absorbed dose and dose equivalent rates using passive dosimeters at Piers-1 module on the ISS through 8 sessions with different durations between 2007 and 2012. The passive dosimeters consisted of a combination of luminescent detectors and CR-39 plastic nuclear track detectors. Each session period has been ranging from 0.5 to 5.5 yrs. In the typical case of less than 1 yr, CR-39 analysis has been carried out with high speed optical microscope system (HSP-1000). The longer exposure samples have been analyzed with atomic force microscope. The gradual and dynamical variations of LET spectra and dose rates were observed, which depend on the solar activity and the other ISS parameters. We present the long-term variations of space radiation environment inside ISS Piers-1 module between 2007 and 2012.","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":"18th Workshop on Radiation Monitoring for the International Space Station(18th WRMISS)","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":"Kodaira, Satoshi"}],"nameIdentifiers":[{"nameIdentifier":"641620","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawashima, Hajime"}],"nameIdentifiers":[{"nameIdentifier":"641621","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Uchihori, Yukio"}],"nameIdentifiers":[{"nameIdentifier":"641622","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitamura, Hisashi"}],"nameIdentifiers":[{"nameIdentifier":"641623","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kurano, Mieko"}],"nameIdentifiers":[{"nameIdentifier":"641624","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yasuda, Nakahiro"}],"nameIdentifiers":[{"nameIdentifier":"641625","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kobayashi, Ikuo"}],"nameIdentifiers":[{"nameIdentifier":"641626","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koguchi, Yasuhiro"}],"nameIdentifiers":[{"nameIdentifier":"641627","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Akatov, Yury"}],"nameIdentifiers":[{"nameIdentifier":"641628","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tolochek, Raisa"}],"nameIdentifiers":[{"nameIdentifier":"641629","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shurshakov, V.A."}],"nameIdentifiers":[{"nameIdentifier":"641630","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"et.al"}],"nameIdentifiers":[{"nameIdentifier":"641631","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小平 聡","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"641632","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"川嶋 元","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"641633","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内堀 幸夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"641634","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"北村 尚","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"641635","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"蔵野 美恵子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"641636","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":"Long-term dose variations in the ISS Piers-module measured by passive dosimeters","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Long-term dose variations in the ISS Piers-module measured by passive dosimeters"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-09-09"},"publish_date":"2013-09-09","publish_status":"0","recid":"65126","relation_version_is_last":true,"title":["Long-term dose variations in the ISS Piers-module measured by passive dosimeters"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:03:45.713702+00:00"}
