Application of the thermoluminescent technique for calibration and dosimetry of 90 Sr + 90 Y applicators

چکیده
Dermatological and ophthalmic applicators are used in brachytherapy for the treatment of superficial lesions of skin and eyes. The calibration of these applicators should be realized periodically, according to quality control programs and international recommendations about dosimetry and calibration of brachytherapy sources. Thin thermoluminescent dosimeters of CaSO4:Dy were utilized in this work for the calibration of different applicators using a dermatological applicator as reference. The absorbed dose rates obtained were compared with those of their calibration certificates. Depth dose curves were obtained for all applicators using absorbers of different thicknesses.

متن کاملThe use of gel dosimetry to measure the 3D dose distribution of a 90Sr/90Y intravascular brachytherapy seed.
Absorbed dose distributions in 3D imparted by a single (90)Sr/(90)Y beta particle seed source of the type used for intravascular brachytherapy were investigated. A polymer gel dosimetry medium was used as a dosemeter and phantom, while a special high-resolution laser CT scanner with a spatial resolution of 100 microm in all dimensions was used to quantify the data. We have measured the radial d...
متن کاملEvaluation of Interferences on Measurements of 90 Sr / 90 Y by the TDCR Čerenkov Counting Technique
Over the last few decades many techniques have been developed for determination of Sr/Y in the environment. Čerenkov counting technique (developed in the 1960s) is widely used, but can be further developed by the application of emerging technologies. For example, it is believed that the application of the triple-to-double coincidence ratio (TDCR) liquid scintillation counting method can be used...
