Reimagining nuclear materials for the future of medicine
Nuclear medicine has come a long way since Henri Becquerel first observed the penetrating energy of radioactive materials in 1896. Today, technetium-99m alone is used in more than 40 million diagnostic procedures every year—from cardiovascular imaging and bone scans to cancer detection—making it the undisputed workhorse of nuclear medicine. That single statistic tells you something important: An enormous portion of modern diagnostic medicine rests on a surprisingly narrow foundation, one built around a small number of aging research reactors that were never originally designed for continuous isotope production.
UWC 2022 speaker
Daniel H. Dorman was appointed the Executive Director for Operations of the United States Nuclear Regulatory Commission in October 2021. This is the highest-ranking career position in the agency, with responsibilities for overseeing the agency’s operational and administrative functions, and serving as the chief operating officer.
He previously served as both Deputy Executive Director for Reactor and Preparedness Programs and Acting Deputy Executive Director for Materials, Waste, Research, State, Tribal, Compliance, Administration and Human Capital Programs in the Office of the Executive Director for Operations.
Mr. Dorman joined the NRC in 1991 as a project engineer in the Office of Nuclear Reactor Regulation (NRR). He has served in senior management positions in the Offices of Nuclear Regulatory Research; Nuclear Security and Incident Response; Nuclear Material Safety and Safeguards; and Nuclear Reactor Regulation. From 2014 to 2017, Mr. Dorman served as Regional Administrator, Region I.
Prior to joining the NRC, Mr. Dorman served as a submarine officer in the U.S. Navy's nuclear power program with a subspecialty in joint intelligence operations. He received a bachelor's degree in naval architecture and marine engineering from the Webb Institute of Naval Architecture. He received the NRC's Meritorious Service Award in 1998 and the Presidential Rank Meritorious Executive Award in 2008.
