Preparation of Medical Th-Ra Radionuclide Generator Based on SiO@TiO Microspheres.

Ra ( = 3.63 d), an α-emitting radionuclide, holds significant promise in cancer endoradiotherapy. Current Ra-related therapy is still scarce because of the lack of reliable radionuclide supply.

Simple and efficient method for producing high radionuclidic purity In using enriched Cd target.

In this work, a simple and efficient method for producing high radionuclidic purity In from an enriched Cd target was developed. The enriched Cd metal target formed by cyanide-free electroplating was bombarded with protons of 21 MeV in a CS-30 cyclotron. Then, we explored a purification scheme using CL-P204 cation exchange resin wherein 98% of the In in the bombarded target could be extracted in less than 1 h.
