William J. Brady, BS, was former Principal Health Physicist, Reynolds Electrical and Engineering Co., Inc. (REECo), a subsidiary of EG&G Inc., at the Nevada Test Site (NTS). For 35 years he held health physics and technical positions and was director of the Rad Safe Division Reactor Branch and director of the Laboratory Branch. He wrote the first NTS monitoring manual (1956) and emergency monitoring manual (1957), and developed the personnel radiation dosimeter worn at the NTS for 26 years. In 1957 he started collecting US dosimetry records for nuclear testing and put them into a computerized Master File during 1966–1969. Those records were the basis of research used by the Nuclear Test Personnel Review (NTPR) program of the Defense Nuclear Agency (DNA). He continued assisting DNA as a dosimetry expert until retirement in 1991 and wrote several histories of underground testing. Mr. Brady is a past scientific advisor of the National Association of Atomic Veterans. In 1988, he received the Department of Energy’s highest department commendation, the Award of Excellence, “In recognition of significant contributions to radiological safety in support of the weapons testing program at the Nevada Test Site.” He has served on two prior NRC committees, one on ionizing-radiation dosimetry and the other on film-badge dosimetry in atmospheric tests.
Thomas Gesell, PhD, is professor of health physics, director of the Technical Safety Office, and director of the Environmental Monitoring Program at Idaho State University. He has worked in multiple capacities for the DOE Idaho Operations Office, including deputy assistant manager for Nuclear Programs, and director of the Radiological and Environmental Sciences Laboratory on the Idaho National Engineering Laboratory site. Dr. Gesell was a faculty member of the University of Texas School of Public Health in Houston for 10 years. Dr. Gesell is a member of several committees and professional organizations, including the EPA Science Advisory Board’s Radiation Advisory Committee and the National Council on Radiation Protection and Measurements (NCRP). He chaired committees whose work led to three publications of the NCRP and served on one previous committee of the National Research Council. He is a fellow of the Health Physics Society and was recently elected to its Board of Directors. Dr. Gesell was also a consultant to the President’s Commission on the Accident at Three Mile Island. Dr. Gesell was coauthor of Environmental Radioactivity from Natural, Industrial and Military Sources (1997) with Merril Eisenbud.
