The world's first stand-alone low-energy high-intensity heavy-ion accelerator facility (LEAF), developed by the Institute of Modern Physics of the Chinese Academy of Sciences, recently passed the expert panel acceptance inspection organized by the National Natural Science Foundation of China.

The LEAF can provide intense heavy-ion beams and mixed ion beams of various charge states from light to heavy elements, offering advantages such as high beam intensity, high charge state, diverse ion species, and a wide range of energy variations.

With the upgrading of ion accelerators and the evolution of accelerator technologies, frontier research in ion beam physics has continuously deepened human understanding of the world, and related application technologies have been widely adopted in various fields.

Chinese scientists extract cancer-fighting nuclides from rare earth minerals
These nuclides are known for their potential in targeted alpha-nuclide therapy (TAT), a promising treatment for various cancers, including breast, pancreatic and prostate cancer, according to the press center.

However, their supply remains severely limited. The extraction of lead-212 and bismuth-212 nuclides from natural thorium is expected to fundamentally address this issue.
...
In addition to lead-212 and bismuth-212, the team is also working on extracting radium-228, thorium-228 and radium-224 nuclides, according to Wei Yuezhou, a professor leading the research team.
