A team of Berkeley Lab chemists has overcome these obstacles to report the first study characterizing some of its properties, opening the door to a better understanding of the remaining transuranic elements of the actinide series. ....
Date Time Discoveries at Edge of Periodic Table: First Ever Measurements of Einsteinium Berkeley Lab scientists Leticia Arnedo-Sanchez (from left), Katherine Shield, Korey Carter, and Jennifer Wacker had to take precautions against radioactivity as well as coronavirus to conduct experiments with the rare element, einsteinium. (Credit: Marilyn Sargent/Berkeley Lab) Since element 99 – einsteinium – was discovered in 1952 at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) from the debris of the first hydrogen bomb, scientists have performed very few experiments with it because it is so hard to create and is exceptionally radioactive. A team of Berkeley Lab chemists has overcome these obstacles to report the first study characterizing some of its properties, opening the door to a better understanding of the remaining transuranic elements of the actinide series. ....

TAT recruits drugs containing radioactive materials called alpha-emitting radioisotopes or radionuclides combined with cell-targeting molecules like antibodies. As alpha-emitting radioisotopes decay, they emit radiation in the form of highly energetic particles called alpha particles. Cell-targeting antibodies guide these alpha-emitting radioisotopes, like super-tiny guided missiles, to their final destination: cancer cells. ....
