Correction factors due to scattered radiation and the geometry of the <jats:sup>192<\/jats:sup>Ir sources were also sought to be determined. The computational simulation was validated by comparing some parameters of the experimental results with the computational results. These parameters were: verification of the inverse square law of distance, determination of (RAKR), analysis of the source spectrum with and without encapsulation, and the sensitivity curve of the Sourcecheck 4PI ionization chamber response, as a function of the distance from the source along the axial axis, using the microSelectron-v2 (mSv2) and GammaMedplus (GMp) sources. Kerma was determined by activity in the Reference air, with calculated values of 1.725 \u00d7 10<jats:sup>\u22123<\/jats:sup> U. Bq<jats:sup>\u22121<\/jats:sup> and 1.710 \u00d7 10<jats:sup>\u22123<\/jats:sup> U. Bq<jats:sup>\u22121<\/jats:sup> for the ionization chamber NE 2571 and TN 30001, respectively. The expanded uncertainty for these values was 0.932% and 0.919%, respectively, for a coverage factor (k = 2). The correction factor due to the influence of the aluminum fixing support for measurements at 1 cm and 10 cm from the source was 0.978 and 0.969, respectively. The geometric correction factor of the sources was k<jats:sub>sg<\/jats:sub> = 1.005 with an expanded uncertainty of 0.7% for a coverage factor (k = 2). This value has a difference of approximately 0.2% compared to the experimental values.<\/jats:p>","DOI":"10.1088\/2057-1976\/ad35cd","type":"journal-article","created":{"date-parts":[[2024,3,20]],"date-time":"2024-03-20T22:20:40Z","timestamp":1710973240000},"page":"035034","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Calibration system correction factor for measuring the reference air kerma rate (RAKR) applied to high dose rate <sup>192<\/sup>Ir sources (HDR)"],"prefix":"10.1088","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8218-1049","authenticated-orcid":true,"given":"Douglas Batista","family":"da Silva","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6120-0909","authenticated-orcid":false,"given":"Ademir Xavier","family":"da Silva","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos Frederico Estrada","family":"Alves","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7995-3191","authenticated-orcid":false,"given":"Luis Alexandre Gon\u00e7alves","family":"Magalhaes","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","published-online":{"date-parts":[[2024,4,23]]},"reference":[{"key":"bpexad35cdbib1","doi-asserted-by":"publisher","first-page":"161","DOI":"10.1118\/1.3056462","article-title":"Air kerma standard for calibration of well-type chambers in Brazil using 192Ir HDR sources and its traceability","volume":"36","author":"Di Prinzio","year":"2009","journal-title":"Med.
