John Cardarelli II, Captain US Public Health Service Officer, Cincinnati, OH, USA, Brant Ulsh, M. H. Chew & Associates, Livermore, CA, USA: The USEPA uses the linear no-threshold (LNT) model to estimate cancer risks and determine cleanup levels in radiologically contaminated environments. The LNT model implies that there is no safe dose of ionizing radiation; however, adverse effects from low dose, low-dose rate (LDDR) exposures are not detectable.
Neil Alexander, Ph.D. radiation damage in steels, business strategist, consultant and advocate for nuclear energy: Eating is a risk, but not eating is a greater one. Let us remember that many other things that are not radioactive can also initiate cancer. Bacon for example. And for all we know that works on a LNT basis. That next rasher may literally be the death of you, or that cup of coffee. And don’t get me on the subject of beer, wine or anything else with alcohol in it.
Ludwig Feinendegen, M.D., former director of the Department of Nuclear Medicine, University Hospital, Heinrich Heine University Duesseldorf, Germany, 2010 Marie Curie Prize - Jerry Cuttler, D.Sc. in nuclear sciences and engineering, recipient of 2011 International Dose-Response Society Award for Outstanding Career Achievement: This is a summary statement about low dose radiation from all the articles by these scientist posted on efn-usa.org. "By far, the dominant risk of cancer is from the oxidation effects of oxygen we breath, not low dose radiation."
Dr. A. David Rossin is a Center Affiliated Scholar, Center for International Security and Arms Control, Stanford University. He was President of the American Nuclear Society (1992-93) and served as Assistant Secretary for Nuclear Energy, USDOE, in 1986-87: He initiated this letter to the National Academy of Sciences recommending that guidelines for radiation risk assessment be based on science rather than the arbitrary Linear No Threshold Model.
