Monte 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 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 کاملClimate monitoring before and during limnological studies: a needed integration.
Evaluation and assessment of freshwater quality of lakes, rivers and reservoirs is a complex technical operation. These assessments at present need to be done at local, regional and global levels (McCarthy et al., 2001). Since aquatic ecosystems worldwide are under anthropogenic stress, limnological studies are necessary for evaluation of these stresses and to develop tools to convert speedily ...
متن کاملApplication 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...
