AMY BERRINGTON DE GONZALEZ is an investigator in the Radiation Epidemiology Branch at the National Cancer Institute (NCI) and adjunct faculty at the Johns Hopkins Bloomberg School of Public Health. At NCI, Dr. Berrington de Gonzalez has led the development of the NCI Radiation Risk Assessment Tool, which is interactive computer software designed to estimate the lifetime risk of cancer (with uncertainty intervals) following complex exposure histories. She has also used this software to conduct a research program projecting cancer risks from a large number of medical exposure scenarios including CT scans, nuclear medicine tests, and mammog-raphy screening. Her research interests include methods to improve radiation risk projection and the conduct of epidemiological studies of cancer risks from both low- and high-dose medical radiation exposures. She has served on the U.K. Health Protection Agency’s Advisory Group on Ionizing Radiation and Solid Cancer, as a special adviser on radiation and health to the World Health Organization, and as a committee member on the U.K. government’s Advisory Committee on Breast Cancer Screening. She was a member of the organizing committee for the 2009 Conference on Uncertainties in Radiation Dosimetry and Their Impact on Risk Analysis. Dr. Berrington de Gonzalez earned her Ph.D. in radiation epidemiology from the University of Oxford.
B. JOHN GARRICK is an independent consultant with Garrick Consulting. He was a co-founder of PLG, Inc., an international engineering, applied science, and management consulting firm, from which he retired as president and chief executive officer. His professional interests include risk assessment in nuclear energy, space and defense, chemicals and petroleum, and transportation. He is a member of the National Academy of Engineering and a past president of the Society for Risk Analysis and has received the society’s Distinguished Achievement Award. Dr. Garrick was appointed to the U.S. Nuclear Regulatory Commission Advisory Committee on Nuclear Waste and served for 10 years, 4 years as chair. President George W. Bush appointed Dr. Garrick to the U.S. Nuclear Waste Technical Review Board with the designation of chairman in 2004. Dr. Garrick received his B.S. in physics from Brigham Young University and his M.S. and Ph.D. in engineering and applied science from the University of California, Los Angeles. He is also a graduate of the Oak Ridge School of Reactor Technology. He served on many NRC committees, including several associated with the space program.
DUDLEY T. GOODHEAD is retired from the Medical Research Council’s (MRC’s) Radiation and Genome Stability Unit, Harwell, United Kingdom, where he served as director. The Genome Stability Unit carried out basic research on the relationship of genome stability to human health, including how DNA may be damaged by radiation and other agents and how the cellular repair systems act to restore normality. Dr. Goodhead continues as a visitor at MRC Harwell and assists the European Commission’s research program as well as a number of agencies in the United States and the United Kingdom. His research has been mainly on the biophysics of radiation effects, with particular emphasis on microscopic features of radiation track structure at the atomic, molecular, and cellular levels and their consequent radiobiological and health effects. He has held positions at the University of California, Los Angeles; St. Bartholomew’s, London; and Natal, as well as the Radiobiology Unit at MRC Harwell. Dr. Goodhead has served on a variety of national and international committees on the evaluation of radiation risks, including the Committee on Medical Aspects of Radiation in the Environment in the United Kingdom; consultancies to UNSCEAR and the International Atomic Energy Agency (IAEA), and working groups of the International Agency for Research on Cancer (on carcinogenic risk of gamma rays, neutrons, and internally deposited radio-nuclides) and the Royal Society (on risks from depleted uranium). He was chair of the Committee Examining Radiation Risks of Internal Emitters in the United Kingdom until its final report. In the Queen’s Birthday Honours List, Dr. Goodhead was awarded the Order of the British Empire for services to medical research. He has been the recipient of various other awards, including the Weiss Medal from the Association for Radiation Research, the Failla Medal from the Radiation Research Society, the Douglas Lea Lecturer from the Institute of Physics and Engineering in Medicine and Biology, the Bacq and Alexander Award from the European Society of Radiation Biology, an Honorary Fellowship of the Society of Radiological Protection, the Warren K. Sinclair Lecturer from the NCRP, and the Gray Medal (August 2011) from the International Committee on Radiation Units and Measurements. He earned his D.Phil. in particle physics at the University of Oxford, United Kingdom. He served on the NRC Committee on Health Risks of Exposure to Radon (BEIR VI), Phase II.
