Furthermore, the 90Sr has long biological half-life (˜18 y) in the human body. Due to its chemical similarity to calcium it accumulates in bones and irradiates the bone marrow, causing its high radio-toxicity.\nAssessing 90Sr in the environment is therefore necessary in case of a nuclear disaster. For 90Sr measurement, a new separation laboratory was established at the National Institute for Quantum and Radiological Science and Technology, Japan (QST) in 2012. \nFukushima soil samples were collected in 2013. We have observed a weak correlation between 90Sr and 137Cs activity concentrations in samples (Figure 1), however, the 90Sr concentration was lower with three or four magnitudes than 137Cs.\nIn this presentation, a soil sample collection survey in the Fukushima exclusion zone was accomplished in 2016 and some contaminated hot spots were revealed with air dose rate measurement (>20 µSv/h). In the collected soil samples, 137Cs activity concentrations were over 1000 Bq/g while the 90Sr were over 500 Bq kg 1.","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":"ENVIRA 2017  (International Conference on Environmental Radioactivity)","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":"S.K.Sahoo"}],"nameIdentifiers":[{"nameIdentifier":"652788","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"N.Kavasi"}],"nameIdentifiers":[{"nameIdentifier":"652789","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"T.Aono"}],"nameIdentifiers":[{"nameIdentifier":"652790","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"サフー サラタ クマール","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"652791","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ｋａｖａｓｉ Ｎｏｒｂｅｒｔ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"652792","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"青野 辰雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"652793","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":"Measurement of 90Sr activity in Fukushima soil samples affected by Nuclear Accident","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Measurement of 90Sr activity in Fukushima soil samples affected by Nuclear Accident"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-06-08"},"publish_date":"2017-06-08","publish_status":"0","recid":"66347","relation_version_is_last":true,"title":["Measurement of 90Sr activity in Fukushima soil samples affected by Nuclear Accident"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:49:58.780105+00:00"}
