Several concentrations of 5,5-dimethyl-1-pyrroline-N-oxid (DMPO) solution (from 0.5 to 1680 mmol/l) were prepared and irradiated with an identical dose of X-ray or γ-ray. The density of •OH generation in aqueous solution was evaluated by the electron paramagnetic resonance (EPR) spin-trapping technique using DMPO as an EPR spin-trapping agent. The relationship between the molecular density of DMPO in the samples and the concentration of DMPO-OH generated in the irradiated samples was analyzed. Two different characteristic linear trends were observed in the DMPO-OH/DMPO plots, which suggested •OH generation in two fashions, i.e., mmol/l- and mol/l-level local concentrations. The dose, dose rate, and/or the energy of photon irradiation did not affect the shapes of the DMPO-OH/DMPO plots. Moreover, the addition of 5 mmol/l caffeine could cancel the contribution of mmol/l-level •OH generation, leaving a trace of mol/l-level •OH generation. Thus, the localized mmol/l- and mol/l-level generations of •OH, which were independent of experimental parameters such as dose, dose rate, and/or the energy of photon of low LET radiation, were established.","subitem_description_type":"Abstract"}]},"item_8_relation_13":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"30279619","subitem_relation_type_select":"PMID"}}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.3164/jcbn.18-15","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://www.jstage.jst.go.jp/article/jcbn/advpub/0/advpub_18-15/_pdf/-char/en","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0912-0009","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":"Ogawa, Yukihiro"}],"nameIdentifiers":[{"nameIdentifier":"1024710","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Emiko, Sekine-Suzuki"}],"nameIdentifiers":[{"nameIdentifier":"1024711","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ueno, Megumi"}],"nameIdentifiers":[{"nameIdentifier":"1024712","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakanishi, Ikuo"}],"nameIdentifiers":[{"nameIdentifier":"1024713","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ken-ichiro, Matsumoto"}],"nameIdentifiers":[{"nameIdentifier":"1024714","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yukihiro, Ogawa","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1024715","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Emiko, Sekine","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1024716","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Megumi, Ueno","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1024717","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ikuo, Nakanishi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1024718","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kenichiro, Matsumoto","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1024719","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":"Localized hydroxyl radical generation at mmol/l and mol/l levels in water by photon irradiation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Localized hydroxyl radical generation at mmol/l and mol/l levels in water by photon irradiation"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-01-18"},"publish_date":"2018-01-18","publish_status":"0","recid":"49169","relation_version_is_last":true,"title":["Localized hydroxyl radical generation at mmol/l and mol/l levels in water by photon irradiation"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:05:18.205959+00:00"}
