is an independent, health physics consultant with over 35 y of professional experience in a wide range of radiation protection areas. His areas of expertise include external and internal radiation dosimetry, environmental dose assessment, radiation risk assessment, radiation spectroscopy, health physics training, radiation detection and measurement, and radiological site characterization. Dr. Frazier earned a BA in Physics from Berea College, an MS in Physics from the University of Tennessee in Knoxville, and a PhD in Physics (with health physics emphasis) from the University of Tennessee in Knoxville. His dissertation research was performed at Oak Ridge National Laboratory in the study of interactions of low-energy electrons with large molecules. He completed Comprehensive Certification in health physics from the American Board of Health Physics in 1981 and has been recertified through 2013.

Dr. Frazier is a past-president of the American Academy of Health Physics and a fellow and past-president of the Health Physics Society. He is serving in his second term as an elected member of NCRP and has served on Scientific Committees 46 and 2-1 and on Program Area Committee 2 for the past 7 y. Dr. Frazier was awarded the 1988 Elda E. Anderson of the Health Physics Society and presented the 2007 John C. Villforth Lecture to the Conference of Radiation Control Program Directors. He has served as an advisor to numerous federal agencies on a wide range of health physics and radiation protection topics from operational health physics program design to environmental radiation dose and risk assessments. Dr. Frazier has also served as a consultant to private companies and individuals on numerous health physics issues.
