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. ....

A promising approach to treating cancer - called targeted alpha-particle therapy or TAT - could better harness the curative power of radiation treatments and lessen the severity of their more debilitating side effects.
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. ....
