Milestone – Pure Tb-161 sample – 5 GBq

A sample of pure Terbium-161 with radioactivity over 5 GBq was prepared at the Faculty of Nuclear Sciences and Physical Engineering, CTU in Prague, in the same way as the sample in 1 GBq milestone. Total amount of Tb-161 obtained after separation was 7386,7 MBq (related to the end of beam). Radionuclide purity of prepared …

Milestone – Pure Tb-161 sample – 1 GBq

A sample of pure Terbium-161 with radioactivity over 1 GBq was prepared at the Faculty of Nuclear Sciences and Physical Engineering, CTU in Prague thanks to a newly developed separation system. It was prepared by neutron irradiation of highly enriched Gadolinium-160 and subsequent separation on a chromatographic column with cation exchange resin Dowex 50W×8(H+) (100-200 …

Milestone – Separation system

A production system was developed at CTU to allow reliable routine production of Terbium-161 and its separation from target material, the Gadolinium-160, and other radionuclidic impurities like Ytterbium or Samarium. The separation system is based on column cation exchange chromatography, which is used for both separation and purification steps of the whole process. The system …
