Since the early 1990's, responsibility for the test site has passed on the Kazakh authorities. The population living in the areas surrounding the test site has received so much external and internal radiation doses as a result of atomic tests. For example, in Dolon settlement located about 120km north-east from the test site, external and internal radiation doses were estimated to be about 200 and 230 cSv, respectively, as total doses from 1949 to 1992. Thus, internal dose assessment is one of the main components of the total dose when deriving risk factors for population living in the vicinity of the test site. To serve as an aid to resolve such internal dose estimation, we have started to investigate the present situation of radionuclides in human bone samples. Until now, we collected more than 100 human bone samples around the test site and their concentrations of ^<239,240>Pu,U and ^<90>Sr were chemically separated and measured. The concentrations of ^<239,240>Pu and ^<238>U were found in the range of 0.005-0.23 and 0.09-0.49 mBq/g-ash, respectively. The ^<90>Sr levels were within the rage of 3.9-11.7mBq/g-ash. Most of data found are comparable to those reported for other country's people, but there exist some data with higher levels. Further works are going on to accumulate the data and evaluate the internal doses.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:14403016, 研究期間(年度):2002–2003","subitem_description_type":"Other"},{"subitem_description":"出典：「核被災地域住民の被曝線量評価:旧ソ連核実験場周辺住民の内部被曝線量の構築」研究成果報告書　課題番号14403016\n  (KAKEN：科学研究費助成事業データベース（国立情報学研究所）)\n　　　本文データは著者版報告書より作成","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00034772","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_17":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"金沢大学自然計測応用研究センター"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=10121295","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-14403016/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-14403016/144030162003kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-05"}],"displaytype":"detail","filename":"OC-PR-YAMAMOTO-M-kaken 2004-10p.pdf","filesize":[{"value":"486.0 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"OC-PR-YAMAMOTO-M-kaken 2004-10p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/34785/files/OC-PR-YAMAMOTO-M-kaken 2004-10p.pdf"},"version_id":"ad0a311a-9c45-40eb-b592-c4fdd9e31ded"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"核被災地域住民の被曝線量評価: 旧ソ連核実験場周辺住民の内部被曝線量の構築","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"核被災地域住民の被曝線量評価: 旧ソ連核実験場周辺住民の内部被曝線量の構築"},{"subitem_title":"Radiation dose estimation for people in the areas of nuclear disaster : Internal radiation dose estimation for peoples living in the areas surrounding the former Soviet Union's nuclear test site","subitem_title_language":"en"}]},"item_type_id":"9","owner":"3","path":["2830"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-05"},"publish_date":"2017-10-05","publish_status":"0","recid":"34785","relation_version_is_last":true,"title":["核被災地域住民の被曝線量評価: 旧ソ連核実験場周辺住民の内部被曝線量の構築"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T14:36:28.876584+00:00"}
