Promethium Discovery Set to Rewrite Chemistry Textbooks
24th May 2024
Researchers have uncovered the properties of a rare earth element that was first discovered 80 years ago at the very same laboratory. Their discoveries open a new pathway for the exploration of elements critical in modern technology, from medicine to space travel.
Promethium was discovered in 1945 at Clinton Laboratories, now the Department of Energy’s Oak Ridge National Laboratory, and continues to be produced at ORNL in minute quantities. Some of its properties have remained elusive despite the rare earth element’s use in medical studies and long-lived nuclear batteries. It is named after the mythological Titan who delivered fire to humans and whose name symbolizes human striving.
