The heavy-ion results were compared with X-ray irradiation at the same dose. The ESR signal areas for the two compounds showed a linear relation with the absorbed dose, as well as a logarithmic correlation with the LET. Further analysis was carried out for the radical-production cross section, which showed that stable radicals of the two compounds were produced through collisions of several particles with a single molecule. The relative sigma–value of sucrose for C-ions was 1.29 x 10-12 +/- 0.64 x 10-12 [microm2]. The value of alanine for C-ions was 6.83 x 10-13 +/- 0.42 x 10-13 [microm2]. Considering the structural molecular sizes of sucrose and alanine, the sigma values are similar. In addition, a comparison of the EPR results for the C-ions and X-rays at 50 Gy dose was made. Sucrose spin concentrations produced by C-ions at LET 13.1 and X-rays were similar. Thus, the noble EPR results with X-ray and heavy-ion irradiations imply that sucrose can be useful as a radiation indicator.","subitem_description_type":"Abstract"}]},"item_10004_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"放医研"}]},"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":"中川, 公一"}],"nameIdentifiers":[{"nameIdentifier":"570664","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松本, 謙一郎"}],"nameIdentifiers":[{"nameIdentifier":"570665","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中川 公一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"570666","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松本 謙一郎","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"570667","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":"article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"重粒子線照射によるスクロースのラジカルのESR とESR イメージング検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"重粒子線照射によるスクロースのラジカルのESR とESR イメージング検討"}]},"item_type_id":"10004","owner":"1","path":["7"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-01-17"},"publish_date":"2012-01-17","publish_status":"0","recid":"55768","relation_version_is_last":true,"title":["重粒子線照射によるスクロースのラジカルのESR とESR イメージング検討"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T22:45:37.946588+00:00"}
