Resumo
Dose verification in the patient has become an important part of quality radiotherapy
programs in the departments. The thermoluminescent dosimeters have become
essential for the determination of the dose applied to the patient; these detectors
present a great accuracy and precision in the measurements, thus enabling the
detection of various types of errors in the dosing process. High energy electron beams
(> 5 MeV) have wide use in the medical field mainly in the treatment of various types of
cancer, or in the irradiation of all skin - TSI. TSI dosimetry is difficult because of the
complexity of the treatment in assessing dose uniformity and measuring the absorbed
dose at shallow depths throughout the cutaneous surface area, resulting in wide
variation in the dose distribution. TLDs have proven to be very useful for the distribution
and verification of the dose prescribed for the patient, since the dose may differ from
place to place due to the geometry of the patient's body, overlapping of structures and
asymmetries of the radiation field. In this work the results obtained from the comparative
study and the performance of the LiF:Mg,Ti and CaSO4:Dy detectors used in the clinical
electron beams dosimetry applied to total irradiation of the skin treatment are presented.
Other factors were analyzed in this study such as the homogeneity of the field and the
dose at the calibration point (ZRef), where the detectors were located in the regions
anterior, posterior, right anterior oblique, right posterior oblique and right side.
