Using Geant4, we estimated <jats:sup>131<\/jats:sup>I <jats:italic>S<\/jats:italic> values for 30 radiosensitive target tissues due to emission from the thyroid (Target \u2190 Thyroid) in these phantoms. Our results show that <jats:italic>S<\/jats:italic> values differ between male and female phantoms of the same age and <jats:italic>S<\/jats:italic> values also decrease as phantom age increases. The male-to-female <jats:italic>S<\/jats:italic> value ratio typically varies within 10%, with larger differences observed for the esophagus, extra-thoracic regions, muscles, bladder, and sex organs. On average, <jats:italic>S<\/jats:italic> values for mesh phantoms are approximately 17% higher than those for voxel phantoms, with larger discrepancies for organs remodelled separately in mesh phantoms. The study provides organ <jats:italic>S<\/jats:italic> values for the paediatric population due to <jats:sup>131<\/jats:sup>I exposure from the thyroid, based on the reference mesh-type computational phantoms, enhancing organ dose estimation in emergency situations and during radioiodine treatment.<\/jats:p>","DOI":"10.1088\/1361-6498\/ad8fb8","type":"journal-article","created":{"date-parts":[[2024,11,7]],"date-time":"2024-11-07T22:48:35Z","timestamp":1731019715000},"page":"041512","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Estimation and analysis of S values for <sup>131<\/sup>I using paediatric mesh type reference computational phantoms"],"prefix":"10.1088","volume":"44","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-8102-6119","authenticated-orcid":true,"given":"Pradeep Kumar","family":"Singh","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8511-1081","authenticated-orcid":true,"given":"Hemant Kumar","family":"Patni","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3628-9972","authenticated-orcid":true,"given":"Deepak Kumar","family":"Akar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7374-3679","authenticated-orcid":false,"given":"Pramilla D","family":"Sawant","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2024,11,25]]},"reference":[{"key":"jrpad8fb8bib1","first-page":"25","article-title":"Radioiodine I-131 for the therapy of Graves\u2019 disease","volume":"16","author":"Mumtaz","year":"2009","journal-title":"Malaysian J.
