He holds the title of Director Emeritus Medical/Health Physics Programs and retired as Associate Chair of the Department of Radiology in 2018. He is currently Chair of the Board of Directors and Senior Vice President of NCRP. He is an expert on the biological effects, safety and interactions of ionizing and nonionizing radiation and holds multiple radiation detection technology patents. With over 40 y of experience he has served as a subject matter expert and an advisor to government agencies and institutions throughout the nation and around the world including the U.S. Department of Homeland Security, the U.S. Food and Drug Administration’s Center for Devices and Radiological Health, the World Health Organization, and the International Atomic Energy Agency in the areas of ionizing and nonionizing radiation protection, risk communication, medical physics, and radiological emergency medical management. In 2016, Dr. Bushberg was appointed Vice Chair of the Committee on Man and Radiation which is a Technical Committee of the Institute of Electrical and Electronics Engineers’ Engineering in Medicine and Biology Society. Former Commander in the U.S. Naval Reserve, among other assignments CDR Bushberg served as Executive Officer of the Chemical/Biological/Nuclear Technical Unit 120 Pacific, a highly skilled multidisciplinary military emergency response and advisory team based out of the Alameda Naval Air Station in California. Dr. Bushberg is an elected fellow of the American Association of Physicists in Medicine and the Health Physics Society. He is certified by several national professional boards with specific subspecialty certification in radiation protection and medical physics and currently serves as a Director and Vice Chair of the American Board of Medical Physics. In 2014, Dr. Bushberg was awarded the NCRP Warren K. Sinclair Medal for Excellence in Radiation Science and received the Professor John C. Christiansen Distinguished Alumnus award from Purdue University School of Health Sciences in 2016. Prior to coming to the UC Davis Health System as technical director of Nuclear Medicine, Dr. Bushberg was on the faculty of Yale University School of Medicine Department of Radiology where his research was focused on radiopharmaceutical development. Dr. Bushberg has had responsibility for medical postgraduate education in medical physics, radiation (ionizing and nonionizing) biology and protection for more than 30 y. The third edition of the textbook The Essential Physics of Medical Imaging, authored by Bushberg, Seibert, Leidholdt, and Boone, is used extensively by radiology residency programs throughout the United States.
