Three deciduous trees (Somei-yoshino cherry, Japanese chestnut, and ginkgo) and three evergreen trees (red robin, Japanese black pine, and camellia) were studied. It was found that the Cs-137 concentrations in tree leaves of each species decreased with time exponentially. The effective half-lives of radiocesium in these tree species were calculated, and the values ranged from 156 to 240 d. Although the studied trees were of different types (deciduous and evergreen), interestingly, their values were similar. As their growing climate conditions were the same, they had similar decreasing rates. The radiocesium concentrations in tree leaves and herbaceous plants were also compared for NIRS samples and samples from Fukushima Prefecture. It was found that the concentrations in tree leaves were almost the same as those in herbaceous plants for both sampling areas.","subitem_description_type":"Abstract"}]},"item_10003_relation_10":{"attribute_name":"ISBN","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"9780983618638","subitem_relation_type_select":"ISBN"}}]},"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":"内田, 滋夫"}],"nameIdentifiers":[{"nameIdentifier":"556706","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田上, 恵子"}],"nameIdentifiers":[{"nameIdentifier":"556707","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内田 滋夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"556708","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田上 恵子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"556709","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 paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Change of radiocesium concentration in tree leaves: two years’ observations following the Fukushima Daiichi Nuclear Power Plant accident","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Change of radiocesium concentration in tree leaves: two years’ observations following the Fukushima Daiichi Nuclear Power Plant accident"}]},"item_type_id":"10003","owner":"1","path":["2"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-08-12"},"publish_date":"2014-08-12","publish_status":"0","recid":"54505","relation_version_is_last":true,"title":["Change of radiocesium concentration in tree leaves: two years’ observations following the Fukushima Daiichi Nuclear Power Plant accident"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:00:06.142837+00:00"}
