In this study, X-ray or heavy-ion beam induced ●OH generation was evaluated using fluorescent probe method. The eccentrically-located ●OH generations and the super-localized ●OH generations, which were previously reported based on EPR spin-trapping method, were again confirmed with a different types of analysis. Several concentrations (0.5-208 mM) of terephthalic acid disodium (TPA-Na) in aqueous solution were irradiated with 32 Gy X-ray or a heavy-ion beam (C400, Si490 or Fe500). The amount of ●OH adduct of TPA-Na (hydroxyl terephthalate: hTPA) generated was measured by fluorophotometer (Ex.310 nm/Em. 425 nm). The relationship between the molecular density of TPA-Na in the reaction mixture and hTPA generated was analyzed. The amount of hTPA was increased in proportion to the molecular density of TPA-Na and reached plateau. The inflexion point was not changed by type of ray. The inflexion point suggests the relatively a concentration of ●OH generation. In the case of heavy-ion beam, another linear trend that passed through the origin was again observed when TPA-Na density was extremely high. This second linear increasing of hTPA suggested extremely \"dense\" generation of ●OH.","subitem_description_type":"Abstract"}]},"item_10003_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_10003_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.freeradbiomed.2016.10.069","subitem_relation_type_select":"DOI"}}]},"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":"560097","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sekine, Emiko"}],"nameIdentifiers":[{"nameIdentifier":"560098","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsumoto, Kenichiro"}],"nameIdentifiers":[{"nameIdentifier":"560099","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小川 幸大","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"560100","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"関根 絵美子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"560101","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松本 謙一郎","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"560102","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 paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Verification of Two Different Hydroxyl Radical Densities in Aqueous Solution by Radiation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Verification of Two Different Hydroxyl Radical Densities in Aqueous Solution by Radiation"}]},"item_type_id":"10003","owner":"1","path":["2"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-07-12"},"publish_date":"2017-07-12","publish_status":"0","recid":"54788","relation_version_is_last":true,"title":["Verification of Two Different Hydroxyl Radical Densities in Aqueous Solution by Radiation"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T22:56:46.870998+00:00"}
