Title

EVALUATING THE EFFECT OF ZINC OXIDE NANOPARTICLES DOPED WITH GADOLINIUM ON DOSE ENHANCEMENT FACTOR BY PRESAGE DOSIMETER

Pages

  119-125

Abstract

 Background: New treatment modalies are developed with the aim of escalang tumor absorbed dose and simultaneously sparing the normal structures. The use of nanotechnology in cancer treatment offers some possibilies including destroying cancer tumors with minimal damage to healthy ssues. ZINC OXIDE nanoparcles (ZnO NPs) are wide band gap semiconductors and seem to have a good effect on increasing the absorbed dose of target volume especially when doped with a high Z element. The aim of this study was to evaluate the effect of ZnO NPs doped with GADOLINIUM (Gd) on dose enhancement factor by 6MV photon beam irradiaon.Materials and Methods: Various concentraons of ZnO NPs doped with 5% Gd were incorporated into PRESAGE composion, the 3D chemical dosimeter. Then by using a UV-Vis spectrophotometer opcal density changes and also dose enhancement factor (DEF) were determined.Results: The results of this study showed that by incorporang 500, 1000, 3000 and 4000 mg/ml ZnO NPs doped with Gd into PRESAGE structure the dose enhancement factor of about 1.57, 1.69, 1.78 and 1.82 in a 15 ×15 cm2 field size could be found, respecvely.Conclusion: The results of this study showed that ZnO NPs doped with Gd could be considered as new compound for increasing the absorbed dose.
