JOHN D. BOICE, JR.
is currently Professor of Medicine at Vanderbilt University School of Medicine, Nashville, Tennessee. He was President of the National Council on Radiation Protection and Measurements (NCRP), Bethesda, Maryland from 2012 to 2018. Dr. Boice is an international authority on radiation effects and served on the Main Commission of the International Commission on Radiological Protection for 20 y and as a U.S. advisor to the United Nations Scientific Committee on the Effects of Atomic Radiation for 25 y. During 27 y of service in the U.S. Public Health Service, Dr. Boice developed and became the first chief of the Radiation Epidemiology Branch at the National Cancer Institute.
Dr. Boice has established programs of research in all major areas of radiation epidemiology, with major projects dealing with populations exposed to medical, occupational, military and environmental radiation. These research efforts have aimed at clarifying cancer and other health risks associated with exposure to ionizing radiation, especially at low-dose levels. Dr. Boice's seminal discoveries and over 500 publications have been used to formulate public-health measures to reduce population exposure to radiation and prevent radiation-associated diseases.
He has delivered the Lauriston S. Taylor Lecture at the NCRP and the Fessinger-Springer Lecture at the University of Texas at El Paso. In 2008, Dr. Boice received the Harvard School of Public Health Alumni Award of Merit. He has also received the E.O. Lawrence Award from the Department of Energy — an honor bestowed on Richard Feynman and Murray Gell-Mann among others — and the Gorgas Medal from the Association of Military Surgeons of the United States. In 1999 he received the outstanding alumnus award from the University of Texas at El Paso (formerly Texas Western College). Dr. Boice directs the Million U.S. Radiation Workers and Veterans Study to examine the lifetime risk of cancer following relatively low-dose exposures received gradually over time.
