The radioactivity concentration and fallout of radiocesium measured in Fukushima City during the period from June 2011 until July 2013 are analyzed to evaluate mainly their time dependences. Although on average the two quantities decrease at paces much faster than those of local dose rates, both of them show annual cycles, peaking during winter and spring and bottoming otherwise. These annual cycles, which are somewhat out of phase compared to those in Europe, are formed due to weathering. However, the local radioactivity concentration shows weekly cycles also, increasing on weekdays and decreasing at weekends. The causes of these weekly cycles are presumably vehicular traffic and precipitation. Therefore, both human and natural activities are playing important roles at different timescales on atmospheric migration of radiocesium deposited in Fukushima City."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381137045294147584","@type":"Researcher","foaf:name":[{"@value":"Kazuhiro Akimoto"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00179078"}],"prism:publicationName":[{"@value":"Health Physics"}],"dc:publisher":[{"@value":"Ovid Technologies (Wolters Kluwer Health)"}],"prism:publicationDate":"2015-01","prism:volume":"108","prism:number":"1","prism:startingPage":"32","prism:endingPage":"38"},"reviewed":"false","url":[{"@id":"https://journals.lww.com/10.1097/HP.0000000000000172"}],"createdAt":"2014-11-27","modifiedAt":"2021-05-24","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=Radioactive%20Fallout","dc:title":"Radioactive Fallout"},{"@id":"https://cir.nii.ac.jp/all?q=Time%20Factors","dc:title":"Time Factors"},{"@id":"https://cir.nii.ac.jp/all?q=Radiation%20Dosage","dc:title":"Radiation Dosage"},{"@id":"https://cir.nii.ac.jp/all?q=Japan","dc:title":"Japan"},{"@id":"https://cir.nii.ac.jp/all?q=Cesium%20Radioisotopes","dc:title":"Cesium Radioisotopes"},{"@id":"https://cir.nii.ac.jp/all?q=Radiation%20Monitoring","dc:title":"Radiation Monitoring"},{"@id":"https://cir.nii.ac.jp/all?q=Fukushima%20Nuclear%20Accident","dc:title":"Fukushima Nuclear Accident"},{"@id":"https://cir.nii.ac.jp/all?q=Humans","dc:title":"Humans"},{"@id":"https://cir.nii.ac.jp/all?q=Seasons","dc:title":"Seasons"},{"@id":"https://cir.nii.ac.jp/all?q=Weather","dc:title":"Weather"}],"relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050576424449218304","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Atmospheric resuspension of insoluble radioactive cesium-bearing particles found in the difficult-to-return area in Fukushima"}]},{"@id":"https://cir.nii.ac.jp/crid/1050850247229058816","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Environmental Remediation of the difficult-to-return zone in Tomioka Town, Fukushima Prefecture"}]},{"@id":"https://cir.nii.ac.jp/crid/1360004232272317696","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Weak size dependence of resuspended radiocesium adsorbed on soil particles collected after the Fukushima nuclear accident"}]},{"@id":"https://cir.nii.ac.jp/crid/1360848658420873216","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Fungal spore involvement in the resuspension of radiocaesium in summer"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282679267499904","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"ja","@value":"福島県内の空間線量率監視システムの変遷と課題"},{"@language":"en","@value":"Development and Issues of Air Dose Rate Monitoring Systems in Fukushima Prefecture with Emphasis on Portable Monitoring Posts"},{"@value":"福島県内の空間線量率監視システムの変遷と課題 : 可搬型モニタリングポストを中心に"},{"@language":"ja-Kana","@value":"フクシマ ケンナイ ノ クウカンセンリョウリツ カンシ システム ノ ヘンセン ト カダイ : カハンガタ モニタリングポスト オ チュウシン ニ"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1097/hp.0000000000000172"},{"@type":"OPENAIRE","@value":"doi_dedup___::8521cacad68bcfc1e3cfbf0e9ab2be45"},{"@type":"CROSSREF","@value":"10.5453/jhps.52.13_references_DOI_38IqK3RlajrWpOP8n9eOjJwkvUN"},{"@type":"CROSSREF","@value":"10.1038/s41598-020-66726-y_references_DOI_38IqK3RlajrWpOP8n9eOjJwkvUN"},{"@type":"CROSSREF","@value":"10.1038/s41598-018-37698-x_references_DOI_38IqK3RlajrWpOP8n9eOjJwkvUN"},{"@type":"CROSSREF","@value":"10.1186/s40645-022-00475-6_references_DOI_38IqK3RlajrWpOP8n9eOjJwkvUN"},{"@type":"CROSSREF","@value":"10.1016/j.jenvrad.2017.03.001_references_DOI_38IqK3RlajrWpOP8n9eOjJwkvUN"}]}
