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
