Philosophy of Care

Dr. Bushberg has served as a subject matter expert in ionizing and non-ionizing radiation protection, radiation biology and radiological emergency medical management for the U.S. Department of Homeland Security, the World Health Organization and the International Atomic Energy Agency. He is the author of numerous book chapters including, the Merck Manual chapter on Radiation Injury and has several radiation detection technology patents in the area of radiological emergency response.

Dr. Bushberg is the Sr. Vice-President of the National Council on Radiation Protection & Measurements (NCRP). The NCRP is the nation’s preeminent scientific radiation protection organization, chartered by Congress to evaluate and provide expert consultation on a wide variety of radiological health issues.

Clinical Interests

Dr. Bushberg is an expert in radiation protection, medical physics and the biological effects and safety of ionizing and nonionizing radiation. With more than over 30 years of experience he has served as an advisor to government agencies and institutions throughout the nation and around the world on the biological effects of ionizing and nonionizing radiation exposure, radiation protection and radiological emergency medical response.

Dr. Bushberg is, certified by several national professional boards with specific sub-specialty certification in Nuclear Medicine Physics and Radiation Protection. 

Research/Academic Interests

Dr. Bushberg has responsibility for medical postgraduate education in medical physics, radiation protection, and radiation biology. He is course director for the Annual International Review Course on the Physics of Diagnostic Radiology, Nuclear Medicine and Radiation Biology which he and other UC Davis faculty members developed more than 30 years ago. The textbook “The Essential Physics of Medical Imaging,” 3rd ed, authored by Bushberg, Seibert, Leidholdt, and Boone, is used extensively by Radiology Residency programs throughout the United States.

He served as Scientific Vice-President and chair of the NCRP’s committee on Radiation Protection in Medicine. Dr. Bushberg also serves as a member of the NCRP scientific advisory committee on Non-ionizing Radiation Safety as well as the International Committee on Electromagnetic Safety and International Engineering in Medicine and Biology Society Committee on Man and Radiation (COMAR) which has as its primary area of responsibility the examination and interpreting the biological effects of non-ionizing electromagnetic energy.
