Resumo
In some parts of Brazil, 90Sr/90Y clinical applicators are still used for dermatological and
ophthalmic treatments, despite the availability of new technologies worldwide and the use of
Ru-106/Rh-106 Eye Applicator. This is because they are less expensive and easier to use. Calibration and
periodic recalibration of these applicators to verify the absorbed dose rate are essential to ensure accuracy
in clinical treatments. In this study, the thermoluminescent response of LiF pellets was evaluated to
determine the reproducibility, linearity of response, and dose-response curves. Dose rates for some clinical
applicators were determined using the LiF pellets, a PMMA phantom and the Monte Carlo method,
following a project based on ISO 21439 (2009). This standard recommends the use of small detectors such
as LiF for this type of calibration.
