In this study, three gamma cameras (GCs), two thyroid uptake meters (TUMs) and one whole-body counter (WBC) were calibrated for activity measurements of <jats:sup>131<\/jats:sup>I in the thyroid. Minimum detectable activity was derived for the GCs, the TUMs and the WBC giving that a committed effective dose (CED) in the interval 2.0\u201385 <jats:italic>\u03bc<\/jats:italic>Sv, 13\u2013700 <jats:italic>\u03bc<\/jats:italic>Sv and 0.52\u20136.4 <jats:italic>\u03bc<\/jats:italic>Sv, and thyroid absorbed doses in the interval 0.075\u20132.1 mGy, 0.48\u201317 mGy, and 0.020\u20130.15 mGy, respectively, can be assessed for children, adolescents, and adults. These numbers are based on 10 min measurement, performed at 1, 3 and 7 d after intake, and the CED includes intake by ingestion and inhalation of aerosols Type F, with an activity median aerodynamic diameter of 1 <jats:italic>\u03bc<\/jats:italic>m. For a fractional signal loss of 63% due to dead time, a CED up to 2.0, 84 and 3.6 Sv and thyroid absorbed dose up to 47 Gy, 2000 Gy and 88 Gy for the three systems, respectively, can be assessed for children and intake by ingestion as a worst-case scenario in terms of CED, measured 7 d after intake. This study demonstrates the potential and limitations of using equipment readily available at larger hospitals for estimation of <jats:sup>131<\/jats:sup>I content in thyroid, which could increase the measurement capability following an RN event.<\/jats:p>","DOI":"10.1088\/1361-6498\/ad7ec5","type":"journal-article","created":{"date-parts":[[2024,9,24]],"date-time":"2024-09-24T22:48:46Z","timestamp":1727218126000},"page":"041503","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Usefulness and limitations of various detector systems for estimation of <sup>131<\/sup>I thyroid activity following an RN event"],"prefix":"10.1088","volume":"44","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8389-7049","authenticated-orcid":true,"given":"Martin","family":"Hjellstr\u00f6m","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-3704-7357","authenticated-orcid":false,"given":"Frida","family":"Westerbergh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7558-4368","authenticated-orcid":false,"given":"Eva","family":"Forssell-Aronsson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9854-5030","authenticated-orcid":true,"given":"Mats","family":"Isaksson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","published-online":{"date-parts":[[2024,10,10]]},"reference":[{"article-title":"Report: sources and effects of ionizing radiation","year":"2008","author":"United Nations Scientific Committee on the Effects of Atomic Radiation, UNSCEAR","key":"jrpad7ec5bib1"},{"year":"2017","author":"United Nations Scientific Committee on the Effects of Atomic Radiation, UNSCEAR","key":"jrpad7ec5bib2"},{"key":"jrpad7ec5bib3","doi-asserted-by":"publisher","first-page":"267","DOI":"10.1007\/s00411-021-00896-9","article-title":"Thyroid doses in Ukraine due to 131I intake after the Chornobyl accident.
