A collaboration between the Department of Energy’s Office of Isotope R&D and Production and the Department of Commerce’s National Institute of Standards and Technology has recovered large quantities of radium-226—valued for its use in medical radioisotope production—from radiological waste stored at NIST facilities. Ra-226 is an important element in developing therapies for patients fighting cancer.
