Steven L. Simon, Ph.D.

Organization:National Cancer Institute
Division of Cancer Epidemiology & Genetics, Radiation Epidemiology Branch
Address:NCI Shady Grove
Room 7E442


Dr. Simon received a B.S. in Physics from the University of Texas, an M.S. in Radiological Physics from the University of Texas Health Sciences Center in Dallas and a Ph.D. in Radiological Health Sciences from Colorado State University. Previously he was on the research faculty at the University of Utah, the academic faculty at the University of North Carolina-Chapel Hill, was a medical physicist for the University of New Mexico at Los Alamos National Laboratory, a Senior Staff Officer at the National Research Council, and Director of the Marshall Islands Nationwide Radiological Study. He joined the NCI in 2000.

Dr. Simon has worldwide experience in monitoring nuclear test sites for residual radioactivity (including test sites in the Marshall Islands, Johnston Island, French Polynesia, and Algeria) and at assessing historical radiation doses from nuclear weapons fallout (including Nevada, Kazakhstan, Marshall Islands). He has provided advice over many years to national and international organizations on issues related to environmental contamination from nuclear testing and the related radiation exposures. More recently, he has directed his efforts to estimating historical doses to patients and medical staff from medical diagnostic procedures and to co-directing the Radiation Epidemiology Branch’s Research Program on Radiological and Nuclear Threats, funded by the National Institute of Allergy and Infectious Diseases. He is a recognized expert in dose reconstruction methods for purposes of epidemiologic studies.

Dr. Simon is a member of the National Council on Radiation Protection and Measurements and has been an Associate Editor of Health Physics for 16 years.

Research Interests
