Scientists Recruit New Atomic Heavyweights in Targeted Fight Against Cancer

Researchers from Berkeley Lab and Los Alamos National Laboratory have developed new methods for the large-scale production, purification, and use of the radioisotope cerium-134, which could serve as a PET imaging radiotracer for a highly targeted cancer treatment known as alpha-particle therapy.

Shape-Shifting Selenium; Abrupt Change Found Between Selenium-70 and Selenium-72

Nuclear scientists recently found that the nucleus of the radioactive isotope selenium-72 has a football-like shape. This is similar to the stable, nonradioactive isotopes of selenium, but different from the disk-like shape of radioactive selenium-70 nuclei. This finding helps explain how the interaction between protons and neutrons in nuclei leads to collective behavior.
