The upper limit of the dose estimation by calculation with the linear-quadratic formula of dicentric and ring chromosomes (Dic and Ring) in conventional metaphase analysis is equivalent to a whole-body dose of 8 Gy gamma-rays (1). Furthermore, after high dose exposure (>5-10 Gy), the number of lymphocytes is reduced and the cell cycle is delayed to reach the metaphase. Therefore, it becomes difficult to estimate such high doses as over 8 Gy.\n In Tokai-mura criticality accident that occurred on September 30, 1999, three workers on the site were severely exposed to neuron and gamma-rays. The drastically reduced number of the lymphocytes indicated that the whole-body dose of radiation that they had been exposed to was unprecedentedly high. A new biodosimetry based on scoring drug-induced prematurely condensed ring chromosomes (PCC-R) that we developed just before the accident was applied to these cases (2). To evaluate this new biodosimetry, we compared the PCC-R data with those of Dic and Ring analysis.","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":"放射線生物学とイメージングに関する第4回日仏ワークショップ","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":"Hayata, Isamu"}],"nameIdentifiers":[{"nameIdentifier":"591017","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"早田 勇","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"591018","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 object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Evaluation of a new biodosimetry based on scoring drug-induced prematurely condensed ring chromosome in the criticality cases in Tokai-mura","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Evaluation of a new biodosimetry based on scoring drug-induced prematurely condensed ring chromosome in the criticality cases in Tokai-mura"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2002-08-06"},"publish_date":"2002-08-06","publish_status":"0","recid":"59377","relation_version_is_last":true,"title":["Evaluation of a new biodosimetry based on scoring drug-induced prematurely condensed ring chromosome in the criticality cases in Tokai-mura"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T22:05:37.155367+00:00"}
