The accidents caused the release of a mixture of radioactive substances into the environment. This study measured the concentration of tritium (3H) and iodine-129 (129I) in rainwater samples collected at Tsukuba, 170 km southwest of the plant, during the year following the accident. High 3H concentrations were observed in the rainwater samples collected within one month after the FNPP1 accident. 3H concentrations decreased steadily over time and returned to the levels before the accident. Concentrations of 129I also decreased over time. However, pulses of high 129I concentrations were observed at several other times following the accident. The 129I concentrations were found to be correlated with iron concentrations in rainwater. It is likely that iron oxide, which can absorb iodate ions (IO3–), was the carrier of radiogenic iodine. This study concludes that 129I and also 131I, which is one of the most harmful radionuclides produced in nuclear reactors, can be redistributed to the atmosphere in the months following the deposition of radiogenic iodine on the ground.\n","subitem_description_type":"Abstract"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Geochemical Society of Japan"}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.2343/geochemj.2.0423","subitem_relation_type_select":"DOI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2017 by The Geochemical Society of Japan."}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0016-7002","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Maruoka, Teruyuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawamuto, Takamasa"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ohno, Takeshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Muramatsu, Yasuyuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsuzaki, Hiroyuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsumoto, Takuya"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Aggarwal, Pradeep"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-11-17"}],"displaytype":"detail","filename":"GJ_51-449-455.pdf","filesize":[{"value":"816.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"GJ_51-449-455","url":"https://tsukuba.repo.nii.ac.jp/record/44233/files/GJ_51-449-455.pdf"},"version_id":"616ac9e7-b39d-4f60-9d7e-5268dc17f7e7"}]},"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":"Tritium and iodine-129 concentrations in precipitation at Tsukuba, Japan, after the Fukushima Daiichi Nuclear Power Plant accident","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Tritium and iodine-129 concentrations in precipitation at Tsukuba, Japan, after the Fukushima Daiichi Nuclear Power Plant accident"}]},"item_type_id":"5","owner":"1","path":["2996","6172"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-11-17"},"publish_date":"2017-11-17","publish_status":"0","recid":"44233","relation_version_is_last":true,"title":["Tritium and iodine-129 concentrations in precipitation at Tsukuba, Japan, after the Fukushima Daiichi Nuclear Power Plant accident"],"weko_creator_id":"1","weko_shared_id":5},"updated":"2022-04-27T09:15:34.793212+00:00"}
