Alan Waltar, nuclear engineer, Past President of the American Nuclear Society, Chair ANS - HPS Joint Topical Conference on Applicability of Radiation-Response Models to Low Dose Protection Standards, October 1 - 3, 2018: Preliminary Program. This conference addresses one of the most important issues facing nuclear power and nuclear medicine, how to establish realistic low dose radiation protection standards. Since the beginning of use of nuclear power in the 1950s, the arbitrary Linear No-Threshold Model with Collective Dose Corollary has been used with results that vastly over predict deaths due to exposure to low dose radiation. This has added tremendous costs, held back the use of nuclear power and limited the use of nuclear medicine. This conference aims at working to establish a low dose protection standard that is based on reality of living organisms rather than an unrealistic arbitrary set of rules.

Wade Allison, Emeritus Professor of Physics, Oxford University, UK: Nuclear energy can affect life when a nucleus decays, releasing energy as radiation. Everything, even our own bodiees, contains some natural radioactivity, and nuclear radiation shines on us from space too. If it had been really dangerous, life would have died out aeons ago, when radiation flux was more intense than it is today. To survive the oxidative damage caused by radiation and oxygen, life has evolved a series of amazingly clever design features and strategies.

Howard Cork Hayden, Emeritus Physics Professor, University of Connecticut: Cancer is largely a failure of the immune system. Cells of the body are continuously being damaged and repaired, but suppressing the immune system increases the likelihood of cancer. Low doses of radiation evidently stimulate the immune system, with the result that there is a real hormesis effect. Any dose below about 100 mGy (10,000 mrads) can be considered safe. Normally, we would post just excerpts from this publication. Since the LNT article is a major part of this issue, we post the whole newsletter this one time.

Mohn Doss, Medical Physicist in Diagnostic Imaging. The ALARA concept, As Low As Reasonably Achievable is base on the linear no-threshold (LNT) model assumption and / or low--dose radiation cancer concerns. Do mutations increase linearly with radiation dose? When radiation dose increases, at low doses, mutations decrease. Cancers do not increase linearly with mutations. There are many more reasons to conclude: Mutation model of cancer is not valid. See for example slide 6 / 13.

Rod Adams, Atomic energy expert with small nuclear plant operating and design experience. Financial, strategic, and political analyst.: Excessive regulation of extremely low radiation doses increases the public fears of nuclear technology, increases the costs borne by society, and can deprive society of the full benefit of that technology.” – Edward Maher, Sc.D., Harvard University

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.

Bonne Posma, physicist, Chairman, Nuclear Africa (Pty) Ltd, Founder, Saminco (USA) specializing in electric propulsion systems for off-road vehicles and underground mining conveyances with operations in China, South Africa and USA, principal shareholder in Liquid Coal, Inc. (USA): Radiation 101 is an excellent short treatise explaining this science to students and the public.

Bruno Comby, nuclear engineer, Founder-President of Environmentalists for Nuclear - International, in French, Association des Ecologistes Pour le Nucléaire, http://ecolo.org: This is a report of Bruno Comby's visit to Ramsar, Iran in 2006 to document one of the world's highest levels of naturally occurring radiation and the lives of people and animals living there. Results are that high doses of radiation spread out over time, i.e. relatively low radiation dose rate, show no detrimental signs. The people are living above average life times. This concept needs to be incorporated into design and operation of nuclear power plants and nuclear medicine. The Linear No-Threshold model is not appropriate for low dose and low dose rates.
