Understanding the dose distribution of beta-emitting eye plaques respect to the location of tumor is of importance. In this study, the geometry of CCB, COB and CIB plaques (BEBIG manufacturer) for specific eye tumors were simulated and the effects of different coated radionuclides and plaque materials were investigated, by Geant4 simulation toolkit. For validation, a dosimetric investigation wa...

Background and purpose: Concave eye applicators of Ru-106, a beta emitter source, have a lot of use in brachytherapy of intraocular tumors. This has led to the need of knowing the exact dose distribution caused by beta radiation to the tumor and its normal surrounding tissue. The purpose of this study was the 3D calculation of dose distribution for three Ru-106 plaques: CCA, CCB, and CGD in a h...
