Previously, some geochemical studies of this area were carried out to assess external dose from radionuclides-bearing heavy mineral sands. In this study, radon, thoron and thoron progeny concentrations were measured in about 100 dwellings during three seasons (autumn-winter, summer, and rainy) in a 10- to 12-month period and annual doses due to inhalation of them were evaluated. The measurements were made by passive-type radon-thoron discriminative detectors and thoron progeny detectors in which solid state nuclear track detectors were deployed. The\nresults show that radon and thoron concentrations differ by one order of magnitude depending on exposure periods, while thoron progeny concentration is nearly constant throughout the year. Since thorium-rich sand is distributed in the studied area, exposure to thoron is equal to, or exceeds, exposure to radon and is not negligible for dose evaluation. Based on the measurements, doses due to inhalation of radon and thoron are evaluated as 0.1e1.6 mSv y 1 and 0.2e3.8 mSv y 1, respectively. The total dose is 0.8e4.6 mSv y 1, which is the same order of magnitude as the worldwide value.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.jenvrad.2016.06.009","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0265-931X","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":"Omori, Y."}],"nameIdentifiers":[{"nameIdentifier":"476694","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Prasad, G."}],"nameIdentifiers":[{"nameIdentifier":"476695","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sorimachi, A."}],"nameIdentifiers":[{"nameIdentifier":"476696","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sahoo, S.K."}],"nameIdentifiers":[{"nameIdentifier":"476697","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ishikawa, T."}],"nameIdentifiers":[{"nameIdentifier":"476698","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Vidya, Sagar D."}],"nameIdentifiers":[{"nameIdentifier":"476699","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ramola, R.C."}],"nameIdentifiers":[{"nameIdentifier":"476700","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tokonami, S."}],"nameIdentifiers":[{"nameIdentifier":"476701","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大森 康孝","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"476702","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"反町 篤行","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"476703","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"サフー サラタ クマール","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"476704","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"床次 眞司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"476705","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":"Long-term measurements of residential radon, thoron, and thoron progeny concentrations around the Chhatrapur placer deposit, a high background radiation area in Odisha, India","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Long-term measurements of residential radon, thoron, and thoron progeny concentrations around the Chhatrapur placer deposit, a high background radiation area in Odisha, India"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-10-05"},"publish_date":"2016-10-05","publish_status":"0","recid":"47559","relation_version_is_last":true,"title":["Long-term measurements of residential radon, thoron, and thoron progeny concentrations around the Chhatrapur placer deposit, a high background radiation area in Odisha, India"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:38:21.060119+00:00"}
