Researchers have demonstrated the production, purification, and potential application of cerium-134. The isotope decays into lanthanum-134, which is useful for positron emission tomography (PET) imaging. The results mean that cerium-134 could support medical treatments based on actinium-225 or thorium-227.
One isotope of the extremely rare element Astatine has shown promise in the treatment of malignant brain tumors, ovarian cancer, advanced blood and lymph system cancers. However, because of its short half-life, scientists need a rapid system with high yield to recover the isotope, At-211, for medical use. Scientists have developed a new purification system that results in a high purity, high yield recovery of At-211.
