Although countermeasures are being implemented, with the aim of reducing radiation exposure, little information is available on the effects of decontamination on individual doses among the residents of radioactively contaminated areas. To evaluate the effectiveness of the decontamination measures in reducing individual doses, and to examine the influence of the timing of decontamination and the district, data were analysed for 18 392 adults and 3 650 children in Minamisoma City, Fukushima, who participated in a voluntary screening programme using individual radiation dosimeters (Glass Badge) between June 2013 and September 2016. The dose reduction rates (\n                    <jats:italic>DRR<\/jats:italic>\n                    ) were calculated for one year by comparing the first and last three-month measurement results between areas with and without decontamination. Using a regression approach and Monte Carlo simulation, the dose reduction rate by decontamination eliminating the effect of physical decay (\n                    <jats:italic>DRRd<\/jats:italic>\n                    \u2032) was also estimated as a function of the timing of the decontamination and the dose at the time of starting the decontamination. The annual\n                    <jats:italic>DRR<\/jats:italic>\n                    in areas with decontamination for both adults and children were significantly higher than those in areas without decontamination, depending on the timing of decontamination: 31%\u201336% for 2013\u201314 for adults in decontamination areas and 33%\u201335% for children in decontamination areas, compared to 12%\u201323% and 13%\u201323% for adults and children in areas without decontamination, respectively. There was a positive correlation between\n                    <jats:italic>DRRd<\/jats:italic>\n                    \u2032 and individual doses, and\n                    <jats:italic>DRRd<\/jats:italic>\n                    \u2032 was estimated at 30%\u201340% for adults and children with doses of 3\u00a0mSv y\n                    <jats:sup>\u22121<\/jats:sup>\n                    in 2013 and 2014. This study demonstrated that decontamination does lower individual doses from external exposure. The higher the dose at the time of starting the decontamination, the greater the dose reduction rate by decontamination, regardless of the timing of the decontamination. Our study confirms that decontamination was useful for high-dose areas in the later phases of the incident.\n                  <\/jats:p>","DOI":"10.1088\/1361-6498\/ab280e","type":"journal-article","created":{"date-parts":[[2019,6,10]],"date-time":"2019-06-10T18:15:34Z","timestamp":1560190534000},"page":"854-871","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":28,"title":["Impact of decontamination on individual radiation doses from external exposure among residents of Minamisoma City after the 2011 Fukushima Daiichi nuclear power plant incident in Japan: a retrospective observational study"],"prefix":"10.1088","volume":"39","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8027-202X","authenticated-orcid":false,"given":"Masaharu","family":"Tsubokura","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michio","family":"Murakami","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshitake","family":"Takebayashi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2963-7297","authenticated-orcid":false,"given":"Shuhei","family":"Nomura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyoko","family":"Ono","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akihiko","family":"Ozaki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toyoaki","family":"Sawano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yurie","family":"Kobashi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomoyoshi","family":"Oikawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2019,8,7]]},"reference":[{"key":"jrpab280ebib1","author":"United Nations Scientific Committee on the Effects of Atomic Radiation","year":"2010","type":"book"},{"key":"jrpab280ebib2","author":"United Nations Scientific Committee on the Effects of Atomic Radiation","year":"1988","type":"book"},{"key":"jrpab280ebib3","doi-asserted-by":"publisher","first-page":"e65331","DOI":"10.1371\/journal.pone.0065331","type":"journal-article","article-title":"The relationship between media consumption and health-related anxieties after the Fukushima Daiichi nuclear disaster","volume":"8","author":"Sugimoto","year":"2013","journal-title":"PLoS One"},{"key":"jrpab280ebib4","doi-asserted-by":"publisher","first-page":"297","DOI":"10.1097\/00004032-199603000-00001","type":"journal-article","article-title":"Internal exposure from the ingestion of foods contaminated by 137Cs after the Chernobyl accident.
