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.
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.
