This study aimed to assess the occupational finger dose received by technologists during the preparation and administration of <jats:sup>18<\/jats:sup>F-FDG radiopharmaceuticals in positron emission tomography-computed tomography (PET-CT) whole-body scan procedures. Fifty scans were selected, with one procedure excluded due to a high administered activity. The mean administered activity per scan was 207.2 \u00b1\u200941.8\u2009MBq, with preparation and administration times averaging 1.44 \u00b1 1.30\u2009min and 0.46 \u00b1 0.31\u2009min, respectively. The technologist\u2019s mean total finger dose received during preparation and administration was 253.5 \u00b1 153.3\u2009<jats:italic>\u00b5<\/jats:italic>Sv per procedure. A significant positive correlation was found between the administered activity and occupational dose, with patient\u2019s body mass index, preparation time, and administration time also contributing to dose variation. Based on 703 PET-CT procedures conducted in 2022, the estimated occupational finger dose for a technologist was 178.2\u2009mSv annually. This value is well below the International Commission on Radiological Protection\u2019s maximum permissible dose of 500\u2009mSv. The findings of this study have a significant impact on extremity dosimetry in nuclear medicine in Sri Lanka, as this is the first study of its kind.<\/jats:p>","DOI":"10.1088\/1361-6498\/ad9f72","type":"journal-article","created":{"date-parts":[[2024,12,16]],"date-time":"2024-12-16T22:50:23Z","timestamp":1734389423000},"page":"041514","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Assessing radiation exposure of fingers of PET\/CT technologists during <sup>18<\/sup>F-FDG procedures using active extremity dosimeters: a single-center study"],"prefix":"10.1088","volume":"44","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5470-6637","authenticated-orcid":true,"given":"Vijitha","family":"Ramanathan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"SP","family":"Gamage","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"UIU","family":"Karunathilaka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"WMIS","family":"Wickramasinghe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ranga","family":"Tudugala","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","published-online":{"date-parts":[[2024,12,27]]},"reference":[{"key":"jrpad9f72bib1","doi-asserted-by":"publisher","first-page":"R60","DOI":"10.1088\/1361-6498\/ac31a2","article-title":"Review of extremity dosimetry in nuclear medicine","volume":"41","author":"Kollaard","year":"2021","journal-title":"J.
