Atomic Technology. The nuclear chemist's best-known achievement was the synthesis and isolation of the radioactive element plutonium. He pioneered the creation of new exotic isotopes and elements by bombarding materials with atomic particles in particle accelerators, many of which his research team helped design. He was one of the most important participants in the Manhattan Project, which developed the atomic bomb during World War II.
