Namely, the types of free radicals in PADC are different from each other below and above this critical dose. Changes in FT-IR spectra of carbonate ester in PADC above critical doses for gamma ray and USX exposures have also been observed, while that of ether decreases linearly with increasing absorbed dose. These results are well concordant with previous results obtained with 28 MeV electron beams. They also indicate that at least two hits of electrons are needed to destroy the carbonate ester in PADC. The layered structure of ion tracks in PADC can be explained thanks to these experimental results. Also, some clues for the identification of created radicals have been obtained from the results using both ESR and IR.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"ELSEVIER"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.radphyschem.2019.108628","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.radphyschem.2019.108628","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0969-806X","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":"Kusumoto, Tamon"}],"nameIdentifiers":[{"nameIdentifier":"997861","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Okada, Shogo"}],"nameIdentifiers":[{"nameIdentifier":"997862","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kurashige, Hisaya"}],"nameIdentifiers":[{"nameIdentifier":"997863","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kobayashi, Kazuo"}],"nameIdentifiers":[{"nameIdentifier":"997864","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fromm, Michel"}],"nameIdentifiers":[{"nameIdentifier":"997865","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Quentin, Raffy"}],"nameIdentifiers":[{"nameIdentifier":"997866","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ludwig, Nicolas"}],"nameIdentifiers":[{"nameIdentifier":"997867","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kanasaki, Masato"}],"nameIdentifiers":[{"nameIdentifier":"997868","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oda, Keiji"}],"nameIdentifiers":[{"nameIdentifier":"997869","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Honda, Yoshihide"}],"nameIdentifiers":[{"nameIdentifier":"997870","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tojo, Sachiko"}],"nameIdentifiers":[{"nameIdentifier":"997871","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Jean-Emmanuel, Groetz"}],"nameIdentifiers":[{"nameIdentifier":"997872","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ogawara, Ryo"}],"nameIdentifiers":[{"nameIdentifier":"997873","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kodaira, Satoshi"}],"nameIdentifiers":[{"nameIdentifier":"997874","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Rémi, Barillon"}],"nameIdentifiers":[{"nameIdentifier":"997875","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamauchi, Tomoya"}],"nameIdentifiers":[{"nameIdentifier":"997876","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tamon, Kusumoto","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"997877","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ryo, Ogawara","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"997878","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Satoshi, Kodaira","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"997879","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":"Evidence for a critical dose above which damage to carbonate ester bonds in PADC appear after gamma ray and ultra soft X-ray exposures","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Evidence for a critical dose above which damage to carbonate ester bonds in PADC appear after gamma ray and ultra soft X-ray exposures"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-01-22"},"publish_date":"2020-01-22","publish_status":"0","recid":"78484","relation_version_is_last":true,"title":["Evidence for a critical dose above which damage to carbonate ester bonds in PADC appear after gamma ray and ultra soft X-ray exposures"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:51:16.492271+00:00"}
