eparation of Ce-134 from dissolved lanthanum target by anion exchange chromatography.
A robust supply of Ce-134 is an essential step in advancing the use of alpha emitters for cancer therapy due to its promise as a PET imaging analog for actinium-225 (Ac-225) and thorium-227 (Th-227).

Fighting Cancer on Earth and in Space Using High-Energy Protons

Scientists on Earth use high-energy protons to create isotopes to detect and treat cancer. In space, however, these same high-energy protons can pose a risk to spacecraft and the health of the astronauts traveling in them.

This can improve conversion of the radioisotope source’s beta decay emissions to electricity by using two converters instead of one. The result is greater power density for the power source.

New Approach to Radioisotope Power Sources for Improved Efficiency, Long Life

NextGen power sources may satisfy the need for long-term, compact power for use in remote or extreme environments.

Her work is paving the way for enclosing isotopes in the same polymers for targeted treatment of cancer cells.
