Application of the thermoluminescent technique for calibration and dosimetry of 90 Sr + 90 Y applicators
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 wo...
متن کاملMonte Carlo Dose Calculation of 90 Sr/ 90 Y Source in Water Phantom
Introduction: 90 Sr/ 90 Y source has been used for the intravascular brachytherapy to prevent coronary restenosis in the patients who have undergone angioplasty. The aim of this research is to determine the dose distribution of 90 Sr/ 90 Y source in a water phantom. Materials and Methods: In the present work, MCNP code has been applied to calculate the dose distri...
متن کاملRelationship between sickness absence and meteorological factors.
Sickness absence rates are higher in winter than in summer and also the incidence of many diseases is affected by climatic conditions. Both these facts lead one to suspect that there is a genuine causative relationship between the weather and sickness absence. The object of this investigation is to develop a model to illustrate this relationship in order to obtain some idea of its precise form....
متن کاملDocking 90 Sr radionuclide in cement : An atomistic modeling study
Cementitious materials are considered to be a waste form for the ultimate disposal of radioactive materials in geological repositories. We investigated by means of atomistic simulations the encapsulation of strontium-90, an important radionuclide, in calcium–silicate–hydrate (C–S–H) and its crystalline analog, the 9 Å-tobermorite. C–S–H is the major binding phase of cement. Strontium was shown ...
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...
