Abstract
This paper describes development of 169Yb-seeds by encapsulating 0.6-0.65Â mm (Ï) sized 169Yb2O3 microspheres in titanium capsules. Microspheres synthesized by a sol-gel route were characterized by XRD, SEM/EDS and ICP-AES. Optimization of neutron irradiation was accomplished and 169Yb-seeds up to 74Â MBq of 169Yb could be produced from natural Yb2O3 microspheres, which have the potential for use in prostate brachytherapy. A protocol to prepare 169Yb-brachytherapy sources (2.96-3.7Â TBq of 169Yb) with the use of enriched targets was also formulated.
