Radiation-Response Models to Low Dose Protection Standards (American Nuclear Society, Health Physics Society, Alan Waltar) USA world08.May.2018
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.
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
