Working safely at the frontiers of science

摘要

Glenn T. Seaborg, world- renowned radiochemist, codiscovered plutonium and nine other transurani- um elements. While work- ing on the Manhattan Project, he devised a method of extracting and purifying plutonium. In 1944, his "actinide concept" of heavy element electronic structure changed the peri- odic table to include the transition series of transuranium elements. Dr. Seaborg shared the 1951 Nobel prize In chemistry for his work with the new Elements.
