In the PHITS simulation, an imaginary spacecraft was irradiated isotropically by cosmic rays with charges up to 28 and energies up to 100 GeV/n, and the dose reduction rates due to water shielding were evaluated for 5 types of doses: the dose equivalents obtained from the LET and linear energy spectra, the dose equivalents to skin and red bone marrow, and the effective dose equivalent. The results of the simulation indi cate that the dose reduction rates differ according to the type of dose evaluated. For example, 5 g/cm2 water shielding reduces the effective dose equivalent and the LET dose equivalent by approximately 14% and 32%, respectively. Such degrees of dose reduction can be regarded to make water shielding worth the efforts required to install it.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0010-9525","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":"Sato, Tatsuhiko"}],"nameIdentifiers":[{"nameIdentifier":"462228","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Niita, Kohji"}],"nameIdentifiers":[{"nameIdentifier":"462229","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shurshakov, V.A."}],"nameIdentifiers":[{"nameIdentifier":"462230","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yarmanova, E.N."}],"nameIdentifiers":[{"nameIdentifier":"462231","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nikolaev, I.V."}],"nameIdentifiers":[{"nameIdentifier":"462232","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iwase, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"462233","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sihver, L."}],"nameIdentifiers":[{"nameIdentifier":"462234","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mancusi, D."}],"nameIdentifiers":[{"nameIdentifier":"462235","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Endo, Akira"}],"nameIdentifiers":[{"nameIdentifier":"462236","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsuda, Norihiro"}],"nameIdentifiers":[{"nameIdentifier":"462237","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iwamoto, Yosuke"}],"nameIdentifiers":[{"nameIdentifier":"462238","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakashima, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"462239","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakamoto, Yukio"}],"nameIdentifiers":[{"nameIdentifier":"462240","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yasuda, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"462241","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takada, Masashi"}],"nameIdentifiers":[{"nameIdentifier":"462242","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakamura, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"462243","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"保田 浩志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"462244","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高田 真志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"462245","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中村 尚司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"462246","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":"Evaluation of Dose Rate Reduction in a Spacecraft Compartment due to Additional Water Shield","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Evaluation of Dose Rate Reduction in a Spacecraft Compartment due to Additional Water Shield"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-10-01"},"publish_date":"2012-10-01","publish_status":"0","recid":"46402","relation_version_is_last":true,"title":["Evaluation of Dose Rate Reduction in a Spacecraft Compartment due to Additional Water Shield"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:52:15.557387+00:00"}
