One of the few methods to detect these short-range particles is by means of CR-39 plastic nuclear track detector analyzed with an atomic force microscope. However, doe to the LET-dependent angular sensitivity of CR-39, multiple detectors exposed at a range of incident angles to the primary proton beam, must be analyzed in order accurately detemine the LET spectrum, absorbed dose and dose equivalent. The LET spectrum of 160MeV proton induced secondary particles was exprrimentally measured with CE-39, which were exposed at six different incident angles to take into account the intrinsic sensitivity of the critical angle for track registration. The irradiated detectors were chemically processed to remove a 1 μm thick volume of CR-39, The measured LET range of short range tracks was from 15keV/μm up to 1.5MeV/μm. The absorbed dose contribution (Ds/Dp) from secondary particles to primary proton dose was ~1%, while the dose equivalent contribution (Hs/Dp) was found to be ~20%.","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":"平成26年度HIMAC共同利用研究成果発表会","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":"小平, 聡"}],"nameIdentifiers":[{"nameIdentifier":"646641","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小西, 輝昭"}],"nameIdentifiers":[{"nameIdentifier":"646642","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"北村, 尚"}],"nameIdentifiers":[{"nameIdentifier":"646643","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内堀, 幸夫"}],"nameIdentifiers":[{"nameIdentifier":"646644","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Benton, Eric"}],"nameIdentifiers":[{"nameIdentifier":"646645","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小平 聡","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"646646","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小西 輝昭","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"646647","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"北村 尚","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"646648","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内堀 幸夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"646649","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ｂｅｎｔｏｎ Ｅｒｉｃ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"646650","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"CR-39を用いた高エネルギー荷電粒子が人体内中に生成する短飛程二次粒子の線量寄与の研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"CR-39を用いた高エネルギー荷電粒子が人体内中に生成する短飛程二次粒子の線量寄与の研究"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-04-24"},"publish_date":"2015-04-24","publish_status":"0","recid":"65648","relation_version_is_last":true,"title":["CR-39を用いた高エネルギー荷電粒子が人体内中に生成する短飛程二次粒子の線量寄与の研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:57:47.729928+00:00"}
